    :

    This is my first Wifi Adapter purchase ever. Built a PC for my nephews and decided against running Ethernet throughout my sis home.
    Setup was very easy so A+ to that. I downloaded Drivers from website no sweat. My router is in my living room about 20 feet away from the room i set it up in. I was getting a steady 3/5 bars. However, I just couldn’t connect at all, and when i finally did, it kept dropping the connection every 5 sec or so.

    Since i couldn’t move my router into the bedroom to test and i was too lazy to move the pc to living room to retest, I decided to use my Phone as a hotspot. Lo and behold, it connected with full 5 bars and was up and running.

    The mistake i made was messing with my router settings. I toggled with channels, frequency, bands, pw, security type. Same issue on all settings.Then the smarts thing hit me finally. Test my Hotspot from the phone in diff ranges.

    1. Hotspot in bedroom – 5 bars – connects fine
    2. Hotspot outside of bedroom about 8 ft away – 4 bars – connects fine
    3. Hotspot in dining room about 12-14 ft away – 3 bars – unble to connect
    4 Hotspot in Living room about 16 – 20 ft away – 3 bars – unable to join network

    Reinstalled drivers, same issue. I’ve come to the conclusion that the router or AP device would need to be in close proximity with the adapter. I haven’t yet transported the rig to my sis house, but im hoping with the kids room about 10 ft away it should be fine.

    fingers crossed. !!!

    Tested on Ubuntu Linux 12.04 (PC) , RasBMC, and Rasbian with Raspberry Pi motherboard (512M edition)
    Worked flawlessly. Ubuntu worked with no drivers or tweaks needed
    RasBMC required the “Network Configuration” plugin be installed (Simple one-click solution)

    Incredibly small- doesn’t seem to tax the tiny power supply in the Raspberry PI- I have been running it all day, streaming audio and video without a powered USB hub.

    :

    I bought this adapter because it is small and it can be powered from the Raspberry Pi’s USB port without an external powered hub. Given its size I wasn’t expecting great range, but the range is very poor even compared to my low expectation. If you use this, you won’t be able to go more than 75 feet away from your AP and if you want to do any streaming like DLNA or Shairport, the limit for a usable connection is probably 50 feet with line of sight.

    Other than the range limitation, it works great with the Raspberry Pi.

    Following directions, I plugged in the adapter, and then ran the CD. The install program ran into an immediate problem using jargon that was totally foreign to me: “ordinal 3654 not located in dynamic link library LIBEAY32.dll”. No idea what any of that meant.
    I tried restarting the computer and rerunning the install disc, but got very same results.
    Before returning the adapter to Amazon, I tried one last work-a-round. I went into the CD, and found the subforlder my operating system, WinXP. I copied the folder contents to a thumbdrive, and then used it to run its “setup”. Finally, success!

    I am using my Raspberry Pi with the Raspbian distro as a headless MPD Server, so I needed something that could be easily installed without the use of a monitor and this works perfectly. I can’t comment on network throughput, as Im not transferring large amounts of data to my Raspberry Pi, but I can’t imagine this would be much different from any other Wireless-N network adapter out there.

    If you’re interested in a project similar to mine where your Raspberry Pi will be tucked away out of sight without any direct access, heres how to get it going using Raspbian. My instructions below make the following assumptions:

    1. Your Raspberry Pi is already setup and working on your network using the wired Ethernet Port
    2. You already have a working Wireless network up and running and that it accepts new connections using DHCP
    3. You know how to connect to your Raspberry Pi using SSH (or something equivalent)

    Here is all you need to do:

    1. Connect to your Raspberry using SSH (I use PuTTY for Windows)
    2. Type

    sudo nano /etc/network/interfaces

    3. In this file you’ll already see some lines. If this is a new installation of Raspbian, you’ll probably see lines like:

    —- Begin —-
    auto lo

    iface lo inet loopback
    iface eth0 inet dhcp
    —- End —-

    Add the following lines:

    —- Begin —–
    allow-hotplug wlan0
    iface wlan0 inet dhcp
    wpa-ssid
    wpa-psk

    —- End —-

    In the last two lines above, obviously replace with your SSID, spelled exactly the same way (case sensitive) and your password on the last line.

    4. Press CTRL X to save your file and exit to the terminal again
    5. Type ‘sudo reboot’ to restart your Pi.
    6. When it comes up, it should be already connected to your wireless network. If you want to check, type ‘ifconfig’ from the terminal to see information about all network connections, including IP addresses.

    If you are using a distro other than Raspbian, or you have a non standard wireless network, or have static IP addresses, then the above steps most likely will not work for you.

    I bought this to enable an older laptop to use the 5 GHz band on a dual band n-router. I should have read the product specs more carefully. This adapter only works in the 2.4 GHz band, which means it is not truly 802.11n compliant. The limitation makes it essentially a G-band adapter. Most ISPs provide 20-50 Mbs Internet connections. If you are hoping to increase web surfing speeds over 802.11g (54 Mbs), gains are likely to be imperceptible.

    Pros: 1) Impressive range for a device of its size. 2) Truly small adapter, you hardly know it’s there.

    Cons: 1) It is not truly an N-adapter, no 5 Ghz functionality, which was a deal breaker for me. 2) Its speed was limited to 65 mbs per second, only a slight jump from 54 Mbs/sec 802.11g. 3) It has a flashing blue light when operating which they neglected to mention. (Not terrible, but deserves mentioning.)

    It has a maximum speed of 150 Mbs/second which can only be achieved using wide channels (40 Mhz), which you must enable in hardware setup. In the crowded 2.4 GHz band where many devices operate, using wide channels could interfere with other 802.11a/b/g/n devices. Some routers lock out 40 Mhz channels in 2.4 Ghz, and most “fallback” to 20 Mhz width when interference is likely. This is called “coexistence” mode and is part of the 802.11n spec. You may not be able to achieve more than 65 Mbs per second depending your router and traffic in your area even with wide channels selected (which is not recommended at 2.4GHz or in high traffic areas).

    I returned the Edimax. The single band limitation made it essentially a G-band device (not operating in the much faster 5 GHz range). It failed to meet my needs, but it may work for others looking for a very small 2.4 GHz adapter with good range, if speed isn’t the primary concern.

    My dog has an [extremely cheap, budget] Dell Inspiron 15. With lots of tinkering he was able to get Mac OS X Mountain Lion to run. But there wasn’t any connectivity to the internet so he was considering some internal Atheros cards at the same price. Well, with this laptop it’s apparently a pain to disassemble so he was dreading it. He can happily say that he is currently typing this review from his Dell running OS X Mavericks. That’s right. Not just Snow Leopard is supported, but the latest and greatest 10.9 is as well.

    Some things to know:

    EDIT: System Preferences didn’t detect the driver for a while in Mavericks. It showed up as an ethernet port that was disconnected. After a couple reboots, however, it detects as a Wifi dongle.

    You have to download the driver from the manufacturer’s page and copy it over. Install, reboot, and check in your Applications folder for “Wireless Network Utility.” It looks like a program a high school programming class would produce. But don’t let it fool you. It’s a barebones connection tool that WORKS. You can [and should] set presets for commonly used wifi networks [ie your home network] because otherwise you’ll be typing in the info manually every time. But it just works. Finally.

    Sure, it’s only 150Mbps. I was considering internal cards for the 300Mbps but realistically these Hackintosh installs aren’t for heavy usage so any connection at all is good for me!

    If you’re wanting a simple solution for getting your Hackintosh connected to the internet for under $15 then this is what you need! Check the forums, search around, and I’ll vouch for it here. The adaptor just works. Haven’t tries anything less than Mountain Lion but take that chance if you run something older.

    I’ll be adding a screenshot also.

    This little adapter works and at a great price! Its wonderfully compact and the speed feels comfortably fast on my older system.

    That said, it was not easy to set up, but Edimax Customer Support was very helpful. I think the ease of setup has a great deal to do with your wireless router and the router’s software. At the time of purchase, I had a Linksys E3000 router. I hate that router (and I used to LOVE Linksys routers! The hardware was very serviceable, but the software was abysmal!)!

    I purchased this adapter for an old Mac 1.6GHz PowerPC G5, running Mac OS 10.5.8 (Leopard), which did not have built in WiFi. I use this system for older applications that I still need access to (or for when my kids need internet access).

    I downloaded the software from the Edimax site. Setup went smoothly. The Edimax Wireless Network Utility must run in the background to allow wireless access like other wireless adapter of this type. The Edimax Network Utility showed I was connected to my wireless network with my Linksys E3000 wireless router. However, the E3000 required a static IP address and completely manual setup to get a connection to the internet.

    When that router (Linksys E3000) recently died, I replaced it with an Apple Time Capsule. Once I started up the Network Utility, I easily connected to the network. Next I deleted my old Network Adapter profile in Network Settings and set up a new one, entering the DNS server and Search Domain addresses. My IP address was immediately supplied by DHCP and I had my internet connection.

    During use I found that I while can set up the Utility to startup when the system does, I must sign on to the network each time to get network access. The network password does not appear to be saved. With the E3000 this process usually took MANY attempts, over as much as 30 minutes time. Adding devices with the E3000 was alway a chore. With the Time Capsule, connection was immediate. It may be possible to set the Network Utility to auto-connect to the internet, but I have not been successful.

    Use of this adapter is much easier with the Time Capsule. I just start the Network Utility, select the profile and click “apply”. Enter the network password and click “connect”. I then can hide the Utility and use whichever browser or access network drives as I desire. When I finish network activity I quit the Network Utility.

    There is one really odd thing I noticed which is why I gave this router 4 stars instead of 5 and why I quit the Network Utility immediately after use. I was working at my main station in my office while one of my kids left the G5 on and walked away without shutting down (again!). After a while, I hear a sound that started low and increased and increased in volume until it sounds like there is a jet plan in the office with me! It was the fan on the G5! I couldn’t make it stop or shut the system down normally. I had to literally pull the plug.

    As it happens with my kids, they forgot to shut down on other occasions. If they were simply using Word or Powerpoint, no fan. If they browsing the internet… jet plane. I realized that if the Network Utility was left running while not in use, and the computer went to sleep, the G5’s fan would kick on with ever increasing speed. Weird! If the computer was left on and the Network Utility was off, this did not occur. While I have not tried to repeat the jet plane/fan experience since installing the Time Capsule, I don’t need to. I never let the G5 go to sleep with the Edimax Network Utility on.

    I believe there is a software issue here. I had a Netgear Wireless G54 Adapter prior to this. It worked poorly on the rare occasions that it worked, but its software never turned my system into a jet plane. This adapter WORKS even if there is a bug and the workaround is simple – just don’t be lazy, turn the software off when not in use. For the price, I’m very satisfied.

    I use this adapter with a docked MacBook Pro (my personal computer, on which I have both OS X 10.9 and Windows 8) as well as on a Windows 7 desktop. So far, it’s worked flawlessly with all of those interfaces. The MacBook Pro’s bulit-in wi-fi weakens significantly when docked, for some reason, but this adapter does the trick to achieve full speed/connectivity to my wireless network.

    I previously purchased the Medialink – 300 Mbps Wireless N USB Adapter – 802.11n, 2.4 ghz – (Compatible with Windows 8 / Windows 7 / Windows Vista / Windows XP) adapter, which works fine under Windows 7 and 8, but the drivers and wireless utility provided by Medialink for Mac are significantly outdated. With some research and workarounds, I finally got it to work with Mountain Lion, but with the upgrade to Mavericks, it stopped working altogether. Even when it did work, it was somewhat temperamental. It’s also twice the price as this adapter, and not nearly as compact.

    If you have a Mac, this is the adapter you’re looking for. The 10.8 driver works fine under 10.9. You will, however, need to download the drivers from the Edimax website if you have a MacBook, as the MacBook won’t take the mini CD that comes with the adapter.

    My favorite wireless adapter. For windows (including 8 and 8.1) just plug it in and it works. I didn’t even have to use the configuration disc. Fast, good range. Backward compatible with b and g protocols. I have this on all my machines.

    It also works perfectly with Ubuntu linux (as well as windows) – although some types of Ubuntu it will not work out of the box. You’ll have to connect to the internet some other way, download the current driver (you’ll want the Realtek rtl8188-8192 C driver for the chip that this uses) and do a couple of edits to configuration files. And as of this writing if you have 13.10 you’ll might have to google for a package that fixes a driver problem. Once you have that going, the thing is the best, most stable wireless adapter I have used under Linux.

    This was easy to install and communicates with my Airport Extreme. There is about 15 ft and a single wall between it and the router. It works pretty well but I had to connect it to an extension cable and mount it on the desk for max speed. I was hoping to have it on the back of my computer out of sight, but it’s too slow in that configuration. I have a Linksys on another computer farther away, behind two walls, pointing the same direction, and it works at max speed.

    Installed easy with included disk or automatically with Win7 (tried them both). One issue- horrible ping times to router originally(400ms) and slowwwwww.,Light surfing functioned(barely), but a video stream from a camera wouldn’t even pull up. This was at 50′ and 3 walls with a Netgear n300 (wnr2000) router (average consumer grade). At 10 feet it would stream but at partial frame rate. Changed mode from b/g/n to just b/g (I have seen this help slow wireless on other adapters) and “What a difference!”. Not perfection but very acceptable stream and pings (1-4 ms) at the 50′ and 3 wall location. Change a/b/g mode where? Device manager, network adapters,right click nano adapter,properties,advanced,wireless mode, change “value” here. It may have been something about my router settings it did not like, I am really not sure. Since it happened to me, I felt this should be passed on and someone else may benefit from my findings.
    Despite problems a good little adapter in b/g mode. Connection at that distance listed as excellent and linked at 48Mbps.
    After the setting adjustment went from basically unusable to quite acceptable for me.

    I just ordered a second one of these wonderful wifi adapters. They work great and the small size is amazing. I have two very new macbooks (one a retina pro, the other an air). They are brand new, both bought in the last month, and the wifi on both stink. My wifi access point at home isn’t too old. It supports 802.11n and is a major brand name. Still, both laptops can not maintain a wifi connection for more than 30 seconds. After two updates, still no improvement. Many other wifi devices in my house work fine. The best solution for me was to get two of these wifi adapters. Problem solved! They are so small that hopefully no one will notice the shame of my laptops not being able to perform basic functions like wifi.

    Shockingly small. Installs facilely. Works very well.
    A used laptop that I inherited had an internal WiFi card that I could not get to work. After an hour or so screwing around with it, I thought, “screw it, I’ll just go external.” I found the Edimax after a short websearch. Small, inexpensive, and good reviews. I ordered.

    I will update this review if there are any issues with the unit.

    Installation was simple, except for the fact that my XP machine has a fixed disk drive that doesn’t accept small disks. I had to rip the image from the small disk and burn it on a regular CD. After that, the installation auto-ran and the WiFi was connected and working within minutes.
    Download speeds through the router and the DSL modem are comparable to computers on the LAN that are hard wired to the router. Overall WiFi speeds are about 50Mbs, which is plenty fast for anything I would ever want to do on the network. That is about 10 times faster than my DSL speed. The unit has not dropped the connection at all – I have not investigated range, as that is not particularly important to our application.

    Overall, extremely impressed with the technology and the unit – highly recommended, unless your CD/DVD drive does not have a small-disk depression in the tray or button onto which you snap the disk. Some work is required if you have a silly drive like mine (Dell!) that is fixed inside the laptop and sucks in and spits out the disk, rather than having a tray that slides in and out.

    I read another customer review, mentioning that novices would have trouble installing it to XP operating systems. I did appreciate his comments because he was an expert user and he was right.

    I purchased this USB adapter to replace a broken LAN card inside my Acer Aspire One XP netbook, which is a few years old, but still compatible to use for remote access to workplace XP PCs. I also needed my Acer Aspire One to access my ASUS RT-N66U Dark Knight Double 450 Mbps Dual N Band Router.

    Pros:
    It is small, inexpensive, and once you do successfully install it, it does work.
    I tried watching 2 min clips from Hulu. It did perform adequately, but the speed of the connection varied widely from 14.2 to 58 mpbs during playback. My other Windows 7 laptops with working LAN cards did achieve 72 mpbs.
    It is adequate for accessing emails and regular websurfing.
    The Edimax adapter picked up signals roughly 25 to 30 feet away from me, separated by 2 walls, on the same floor. Because I don’t have multilevel housing, I don’t know if it will work vertically. I plan to use it in my office building to see if it can pick up weaker signals.

    Cons:
    It runs slightly hot. Since it is so tiny, I don’t know if the heat will shorten its life. My netbook runs hot, too, which will affect the adapter’s ability to disperse heat.

    The installation was pretty difficult. I think it might have been easier had I used Windows 7.

    Throw away the Quick Start Guide. It is a waste of time. It says only 3 things that are useful. Turn on your computer first. Then plug in the adapter. Cancel the Windows Hardware Wizard when it asks you if you need help installing it.

    It does not say to turn off your broken wireless LAN switch, which I did. Older devices will have these switches. You should deactivate your old LAN device through the START menu or Control Panel, if you don’t have a switch.

    I also removed old network wireless connection SSIDs by right clicking the wireless icon and then choosing “View Available Wireless Networks,” then “Change the Order of Wireless Networks.” I deleted the old ones in preparation for connecting with my new router.

    Restarting may be a good idea.

    After plugging in the adapter, you are supposed to use the CD to install software. Throw it away. The drive won’t read it.

    To get the software, I used an ethernet cord plugged into the router, went to Google, and found […]. Oddly, the website is not written anywhere on the packaging, start guide, or CD.

    Save yourself time. Here is the link to the download site for the XP device driver and utilities:
    […]

    Click on “driver” at the bottom of the screen. Don’t bother downloading the “Manual.” It is the Start Guide and nothing else.

    After you are done unzipping the files and installing them, you will be prompted to restart your computer.

    Meanwhile, you can connect the router to another laptop, using it to access the router dashboard software that shows the network traffic and security settings at the usual 192.168.1.1 site online. The new adapter should be accepted as a Client.

    At some point, unplug the ethernet cord from the ACER netbook.

    2 wireless icons will be X-ed out. The Edimax icon looks like a misshapen Twinkie.

    The wireless icon that is connected to the broken LAN card will always stay inactive.

    “Wireless Network Connection 2” is the icon associated with the adapter. You will want this one to work.

    The tough part is getting the adapter to recognize the router. After clicking the twinkie icon, I could tell that it was trying to associate with the router. The SSID would flash, the IP address would register, but then the numbers would go to zero, zero, zero. I went to the security tabs in the Edimax icon, thinking that typing in the WPA2 passcode would help. It is definitely important, but still no results. I tried disabling and re-enabling the adapter to no avail. I activated AP and then changed back to Station settings. Then …

    I purchased a couple of these to connect my non-wirelees Samsung TV and Toshiba Blue Ray player. While these worked great for the Blue Ray Player and I am able to connect to all the toys and updates, the Samsung TV does not recognize it through the USB connection. The TV is a whole 3-4 years old now so I guess it’s time to upgrade! šŸ˜‰ NOT! Anyhow, I like these little gadgets as they are easy to set-up and use. Really tiny!

    Right off the bat I’ll say that you should prepare yourself to do some troubleshooting, which might include moving your device closer to the wireless signal.

    It’s very small, doesn’t seem all the fragile as some have mentioned (I ended up removing it from USB slots and re-inserting it a bunch of times in a short time span with no apparent loss of fidelity), and the driver installed just fine. For the first couple of hours it seemed to work great. That’s when I started to have problems.

    For some unknown reason, the signal strength weakened down to 50%. We have several other devices that can link to our router wirelessly and none of them were having any issues from that same spot. I messed with numerous settings with no luck and made sure all of our other wireless devices were off. At this point, the desktop it was plugged into is a couple rooms away, maybe about 25 ft from the router. I decided to unplug it and install it on the desktop right next to the router. Blammo, no problems at all, signal strength good, connection quality equally as good. I left it like that for a while, even downloaded some stuff, trying to see if I could get it to crash, and it never did; it worked just fine.

    So, after browsing forums and the manufacturer’s site, I decided the only thing left for me to do was to try moving the device closer to the router. Fortunately, I found a spot only a few feet away from where I originally wanted it and — surprise! — it worked just fine.

    After all that, it seems to be working fine enough for what I want to use it (although the signal strength is still only at about 70%). My recommendation is that it’s definitely good for it’s price, but it’s not the best thing in the world, and if something goes wrong, expect to be doing a lot of troubleshooting and most likely finding very little in terms of assistance.

    EDIT – Now, once again, I am having connection issues despite ZERO changes to the organization of all equipment involved. Can’t say I’m too happy about this. If I figure anything out and it starts working consistently, I’ll change the review score.

    Very very weak wifi adapter. Constantly drops my connection every few seconds. Promises up to 150mps speed. I have a 50mps internet. I get .33 mbs when I am standing right next to the router. It also gets even worse. Download speeds are the slowest I have ever seen them. My laptop gets up to 40mbs while this is just a piece of junk. Returning this really weak adapter. Do not get this. I instantly regretted it after a day.

    :

    The internal Wi-Fi card on my notebook computer failed, so while I was waiting for a replacement, I installed this little jewel. It’s as sensitive as the one that is built into my Dell Inspiron notebook computer and is incredibly tiny. There is no problem leaving it plugged in all of the time, as long as I don’t need the USB port for another peripheral. If you lose your internal Wi-Fi and/or wish to upgrade from “G” to the faster “N”, this is a reasonably-priced way to do it.

    I received promptly. Well packaged. Package (manufacturer box, not Amazon box) was torn slightly at the top. Comes with one page instruction sheet, mini CD and the USB adapter.

    My operating system: Windows 8, 64 bit, 2x USB2.0, 3x USB3.0, 16GB RAM, less than a year old.

    Directions: Somewhat poor. It states to insert adapter into a USB port 2.0 and an installation guide will pop up, but to cancel it. That does not happen so I can’t. No box appears even after pulling it out and reinserting several times. So, it states there is also a mini CD, to insert that. I did. I got a popup box and I was prompted to select a language, I selected English. I immediately got an error message. I tried this 5 or 6 times with the same error message. I was unable to get past the first page for language.

    I called Edimax and customer support was closed. I went to the website, selected SUPPORT and found my device. The PDF for the item was the same as I got with the device, so no help. I had to download, no choice to view. I saw that Windows 8 was supported, so I found the driver list and attempted to download the driver for W8. When I hit download it launced around 50 pages on my desktop. They were so fast I could not stop them. It took around 2 minutes to close them all out. Silly Wabbit attempted to try this again. This time, I had to hit the OFF button for the computer it was launching pages so fast. I restarted my computer. I ran Norton and it said it deleted 66 items. I assume it was from Edimax because I had just ran a FULL SCAN 3 hours earlier and not used the computer since. I do not feel this was a virus or similar, but more like a glitch, My computer seems normal. When I checked INSTALLED PROGRAMS, Edimax Installation Driver was listed.

    I checked my internet connections, apparently it had installed but it was much slower than my factory wireless card. My wireless card gets around 20, when I am on the ethernet/wired, I get around 90-100Mbps. The Edimax was getting 12 at best after three tries using Xfinity Speed Test. The USB adapter identified itself on my computer as Connection 3, Wireless 2, but when I right clicked on it to get PROPERTIES, it would not give the usual property page. I tried this multiple times with the same result. I got the same result with my other two connections. When I unplugged the Edimax, I was able to right click and get PROPERTIES as I normally would. I found this odd but who knows? When testing each, I did disable the other two.

    I called Amazon, explained what happened and we decided returning the item as defective was the best option; UPS will be picking it up tomorrow.

    I regret having to return the item, I was hoping to bypass installing a better wireless card but they are easy to install so……guess I will. And I really don’t mind being tethered to the ethernet cable.

    So, if you decided to order, the website does offer Windows 8 drivers. I hope the download experience for you goes much better than it did for me.

    Sorry Edimax but only 1 star.

    Plugged this little adapter into one of the front panel USB connections on my computer running Ubuntu 12.04, kernel 3.5.0-39. Ubuntu recognized the wireless device immediately, and presented a list of available networks, including the 2 that I use. I tried connecting to those 2 several times, and it took from 20 seconds to a minute for Ubuntu to report a connection. It seemed to report a good signal level, showing 3 bars of 4 available in the display. However, Firefox repeatedly timed out before a connection to a web site could be obtained. I tried moving the computer around, and even tried putting the device on the end of a USB extension cable (a really nice Amazon Basics one), but Firefox was never able to connect to any web site. Another Ubuntu computer sitting close to this one, but with a built-in wireless adapter, connects almost immediately and works fine with the browser. I suspect that this device needs a very strong wireless signal for it to work.

    Well I cheaped out. I already own the Medialink Medialink- 150Mbps Wireless N USB Adapter – 802.11n, 2.4ghz, Windows 2000 / 2003 / XP 32-Bit and 64-Bit / Vista 32-Bit and 64-Bit / Windows 7 32-Bit and 64-Bit Compatible adapter which installs without software (Strike 1 for the Edimax), was up and running in less than 1 minute (Strike 2) and has excellent speed, around 10mbps from a couple rooms away from the router (Strike 3 Eddy ;-). I could only squeak about 1.5mbps out of this pitiful thing.

    Back it goes. Just buy the Medialink and be done with it.

    Super easy install, works great!

    Our wireless router is far across the house and we didn’t want to have to run cables under floors and across rooms so I ordered this little fellow! Don’t lose it as it is very tiny. I suggest putting it in a USB port out of the way so it is undisturbed by plugging in things around around it.

    Solid signal, quick speeds. Think I’m going to order another one for my Mac setup.

    Quick tip. The software interface that comes with it was a little clunky. I chose settings to have Windows manage it. Your preference, I just like the simple Windows 7 interface.

    This is a great example of how to make something very complicated, very simple. Think about it; you’re adding a network adapter to your PC. That’s a big deal. But this made it 100% simple. I literally popped it onto a spare USB port of- get this- an ancient Windows XP machine. Within 3 minutes it was online, boom. Simple instructions, an installer that actually works with one click, and decent signal strength to boot. Definitely recommend this. Small adapter, small package, small install CD, big happy. Wish the range was a little better, but I have 15 installed in various machines and all are working fine.

    This past winter I ordered components for my first computer build, included in these components was my motherboard with included wireless-n adapter. After a recent driver update, my wireless adapter is nearly useless(very slow speeds). After three days of trying to resolve the issue using a shared Ethernet connection from my notebook, I caved and purchased this USB adapter. My download rate has doubled using this adapter. Placement is everything. Surprisingly, My fastest connection is obtained by plugging this nano adapter into my USB 2.0 hub that sits atop my desk. I have also used this adapter with two notebook computers with wireless issues to resolve the issues. The only concern, the software installation disk is a mini-CD and may not work well in slot-loading drives. Overall, very happy with this purchase.

    This product works well, and was auto-detected by both Linux and Windows 7, so I’ve no complaints there. However, the antenna doesn’t seem to be quite as robust as that in other tiny USB adapters I’ve used in the past. Where others show good coverage on my work bench, this one shows low signal. Aside from that, though, it works fairly well, at least in Windows.

    Linux is a bit odd, though — the driver used for this adapter is a bit buggy in Linux, and will tend to lose the ability to see any wireless connections. Removing the adapter and re-inserting it will cause it to reconnect. As this is not an issue in Windows, it’s likely more a problem with the drivers in Linux, but for those looking to purchase it for such, it’s important to know.

    I live in an old Victorian house – with horsehair plaster walls. VERY thick. Wireless modem is downstairs, and I’m upstairs. Ever since I popped this baby in (and went through some hassle getting the driver) I get 4-5 bars consistently!!!! Prior to this I was getting one or two bars, and dropping the signal frequently. I’d hear that familiar Windows “ba-doomp!” when it went offline and sit here cussing at my machine.

    The only hassle I had was with that dang mini-micro-data CD they sent with the drivers on it. I have a tower computer, and it tried to eat the CD because the drawer opens sideways. This is fine for full-sized CD’s, but the little ones don’t “stick” to the side long enough to go in and be read. By the time I’d dug it out it was all scratched up.

    I thought, “Ok, no problem – I’ll find the driver on the website”. Took me a bit, but found it (using my old adapter – which was slow and dropping the signal throughout). Then once I downloaded it, I had to unzip it. Ok, did that, but then there were a TON of items in there – and not one jumped out as, “click me! .exe”. Eventually I double-clicked the right one, ran the diagnostics again and all was right with the world – and I now have FIVE BARS of connection.

    So, learn your lesson from me – turn the tower over (what I consider to be it’s side) when using these little buggars. You’ll save yourself a lot of headache. This wireless adapter is ‘da bomb!

    I bought this from NewEgg about two months ago and have been using it on my desktop computer. On the positive side, the tiny size of the device is really nice. However, given that I’m using this on a desktop, that feature isn’t super important for me.

    The machine I’ve installed it on is down one floor but almost directly under our wireless router. After receiving the device, I noticed immediately that my internet on my desktop was quite slow (I’m only getting 5mbps down even though my ISP promises 15). Before blaming my ISP, I grabbed my laptop (running the same OS and web browser) and placed it next to my desktop. Sure enough, my laptop with its built-in wifi consistently gets the 15mbps that my ISP/router are delivering, but my desktop machine with the edimax is getting much slower speeds. The only difference is the edimax.

    I contacted customer support and they suggested I update the driver. I checked the driver version and it was the latest version on their site. Unfortunately I didn’t return it because the next few days it usually delivered 14-15 mbps speeds. However, over the past two months, the occasions are rare when the edimax delivers full speed wifi to my desktop. Most of the time, my speeds are stuck around 3-6mbps. The device is just inconsistent, unreliable, and usually slow for me. Not sure if it is an overheating issue or something else, but either way, I haven’t been able to get the performance I expected. I’m shopping for something else now!

    This adapter works well until the system sleeps. In both Ubuntu and Win 7, this device does not properly wake from S2/S3, and requires a soft reset to rejoin the network. On the other hand, it’s tiny, cheap, and resetting a wireless adapter is easily scripted, so it’s a reasonable tradeoff.

    Have only tried using this dongle on a Raspberry Pi system and it works great out of the box, no powered hub or anything extra needed. For those having issues with this not working on a Pi make sure your power adapter is providing the correct amount of power to the device. Cheap power adapters can be all over the map as far as the actual power they provide so spend a few bucks more there and save yourself hassles down the line.

    As far as this device itself the speeds are great and so is the distance I can get from the wifi router. A nice, inexpensive addition to a Raspberry Pi to get it up and running on your network and on the Internet. Recommended!
