Edimax EW-7811UN Wireless 802.11b/g/n 150Mbps Nano USB Adaptor
I purchased this Wifi adaptor so that I could relocate my headless music server pc running Ubuntu 11.10 to a location away from ethernet cabling.
The adapter really is small, about the size of a 5 pence coin, the majority of which sits within the usb port so it has a very small profile.
Unfortunately, despite the product being advertised as working with Linux I found that my Ubuntu 11.10 pc would only connect for approximately 5 seconds then disconnect and keep going into a loop of no-connection.
A search on Google came to my rescue in the form of the following: -
and after following the instructions and rebooting my pc this Wifi adaptor has worked flawlessly.
The instructions are straightforward but you must have the confidence to access and modify the files through 'terminal'; this should not be a problem for seasoned Ubuntu users however as novice at this type of thing I found it a little daunting.
Whether this initial setup problem is a fault of the adaptor or Ubuntu I don't know however I have withheld 'one star' on the basis of this problem.
The Ubuntu pc is now relocated approximately 30 foot away from the router and has two solid brick walls and two wooden bookshelves between it. As I type this review it is showing a throughput of 72Mb/s on the pc however my router is showing the connection at only 38Mb/s so who knows which if either is correct. Irrespective of the figures it is fast enough and stable enough to allow the pc to run as a media server.
Overall, I rate this product highly and it only misses out on 5 stars as it wasn't truly plug-n-play.
