    This wireless adapter works great with the Raspberry Pi. It works with all of the operating systems I’ve tried on it (all Linux based: Debian, openelec, raspbian, Sugar, berryboot, etc). I did not have to load a special driver for it to work.

    I did some network performance testing with this adapter and the Raspberry Pi. The results:

    From an NFS server to the local /dev/null: 6.1 MB/s
    From the NFS server to the local SDHC card: 2.8 MB/s
    From the local SDHC card to the NFS server: 4.1 MB/s

    I prefer purchasing products made in the USA but sometimes you don’t know the source. In this case the product arrived in outstanding quality packaging that is the best I have ever seen from an item made in China. The contents included the tiny adapter, a mini CD and a Quick Installation Guide. All this for $9.99. I made the purchase because WD was too cheap to include internet access in their way overpriced $164.00 Hub. This Edimax was easy to install and could actually be set up without the assistance of the CD or Guide. It did take a bit of time to load a 2 1/2 hour movie but once loaded I watched it with no interruptions. This is an outstanding product at a very reasonable price. I don’t usually praise products made in China because most of them are not praise worthy. However, in all honesty and with some reluctance, I have to be truthful and this is a product worthy of kudos.

    USB connected, Wi-Fi (802.11 B/G/N) adapter looks like a USB port cover. It came with a mini-CD filled with drivers. It connected easily to a Cisco/Linksys 4400N Access Point that was located on the other side of the house and provided 68Mbps throughput through the house, ductwork, etc (when located closer to the AP, the Windows XP system reported that it was connected at 148 Mbps, this was not confirm with iperf.exe.

    This adapter was also used with Ubuntu Linux v12 where it connected with the base drivers but an update bought down additional drivers. Due to other issues, more extensive tests were not performed.

    To me, the acid test is, “would I buy another one” and the answer is “yes”, probably later this week or next. The system that this attached to was used to put a browser on a Visio HD TV without having to run wires into the living room. The only network connection is provided by the EV-7811 and the videos that are played come to the system via the internet and via the Edimax adapter.

    This is a purchase I spent a lot of time mulling over because of reviews that said it didn’t work from a distance. I am using it now with an older computer running Windows XP and Ubuntu. It works with both and I did have some connection problems at first but got the driver and software from Edimax’s site and it worked much better. I’m using it one floor above where the router is and it’s working fine so far.

    I will mention that it seems to work best when not being overly interfered with by other electronics.

    I almost returned it after first puchasing it because it seemed the reviews about connectivity over distance were true so I recommend getting the Edimax drivers for this even though it will install and work without them.

    Otherwise I like the size and, of course, the price.

    My wife dropped her laptop and for some reason the Wireless card stopped connecting to our router. It would work if you were sitting right next to the router but not anywhere else in the house. I found a cheap Wireless card replacement on eBay but this didn’t do the trick. Truly I didn’t expect it to work due to the way it was malfunctioning. I assumed the antenna must have been damaged in the fall. I looked into replacing that but found this ultra small profile Adapter. According to what I could tell it was cheaper to go this way than to fix the antenna, so I ordered it. I couldn’t be happier. I’m not sure how this thing makes such a strong connection with such a small profile but it does. There isn’t anywhere in the house where there is a connection issue. Additionally, it’s actually faster than the internal one was as that one was a Wireless g. For the price, the size and the functionality you really can’t go wrong with this. I’m even thinking about getting one for my Dell laptop even though my wireless card works because, once again, my internal card is a Wireless g, so I would pick up speed. I can’t get over how good of a product this is. I would highly recommend this to anyone.

    Excellent to mount mediacenter with my raspberry pi, works really perfect and speed is excellent.
    The problem with raspberry pi as always the driver.
    On the Internet there are good manuals to install this device, not complicated.

    This got good reception when I was near the router but moving more than 10ft away and it took me 20 minutes to download Firefox at an average speed of 10kps. The internet speed is basically dial-up speed. It had good reviews so I thought it would suffice for me but I wish I would have gotten a better one to begin with instead of having to wait two days for the other one to ship to replace this and hopefully give me a better experience.

    At first, this thing was a pain in the arse to set up, and get working. I used the setup wizrd, but still could not get it to receive any signals. It was only after disabling my other network adapters, and uninstalling/reinstalling this one that I got it to work (at least I think that’s what got it to work, i’m still not really sure). But I was installing it on an older computer running windows XP service pack 1, so maybe that was the problem. Also, I can’t say much for the range of this thing, because in my room I don’t have the best internet connection. I’m able to connect with this thing, but I get a poor signal. My ipad gets a good signal though. But to be fair, my wifi router is downstairs and through a wall, so that’s likely the problem. For ten bucks though, I really can’t complain. The thing is so small it tucks away nicely in back, and i’m sure it gets great connection if only I had the router closer.

    When I brought my wireless n router a while back, I also wanted a less messy setup for my desktop PC. My Windows 7 PC did not come with a built in wireless adapter so I searched on Amazon for a wireless adapter that could work with my PC. I happened to stumble across this tiny device which works with wireless n. So I ordered it and it and quickly came to my house.
    Opening the package was kind of messy, I advise you that the adapter is just placed in the box and taking out the container the wrong way will send the adapter falling out. I placed the adapter in one of my usb ports and ran the software setup with the included cd. The setup was very quick and my computer was instantly wireless. I took out the cat5 cable that runs from my computer to the router and there it was one less cable from my cluttered desk.

    Smaller than other adapters.
    Cheaper compared to other brands.
    A blue light to let you it’s working.
    Wireless N compatible.
    Works with Windows 7

    The adapter itself may get hot occasionally.
    The Computer itself may get hot quicker occasionally.

    To this day do not understand why anyone makes a wifi or drive larger than this with modern technology. I have had several devices get damaged by the way they stick out unnecessarily from my laptop’s body. I use this device on a UMPC called an OQO 02 which sits in my palm. The internal wifi is weak so I bought this. This device extends my range three to four times the distance I can be from my router. I am also an Ubuntu Linux user and the device easily works by downloading the Linux driver from the Realtek site. It works plug and play with Ubuntu 12.04. Also works well with Windows XP with the driver supplied in the box. Just be careful not to drop this thing into your couch. There are disadvantages to small things as well.

    I installed this without a hitch and it does just fine connecting to my wireless-n network. Now the problem I had was every single time I rebooted or the laptop woke up from hibernation, the edimax would not connect. In fact, it lost all evidence of having connected to my wifi access point. It was frustrating so I emailed their tech support. They emailed me back and told me to try uninstalling my Acer laptop’s Acer related network utilities. Once I did this, the edimax connected after reboot, after coming out of hibernation, etc. It works great as of now!

    Got this 802.11n wireless USB adapter for a slightly older laptop that came out just before 11n was standard. The fact it’s so tiny means no worries about knocking it out or around when moving the laptop. I was afraid that would mean spotty or poor performance, but that’s just not the case. It reports the signal is stronger than with the 11g connection.

    Installation was simple. Switched off the internal G wireless, plugged in this tiny adapter and loaded up the software. No issues at all and was up in less than 10 minutes. This was the last non-11n device I had, so now I’ve locked the router into 11n mode only. The throughput is noticeably faster for all devices – not just the laptop.
