Edimax EW-7728IN IEEE802.11n on Ubuntu

I recently purchased the Edimax EW-7728IN IEEE802.11n Draft 2.0 wireless card. Although I’ve not tested the performance yet, I have managed to get it to successfully connect to my Billion 7300N 802.11n wireless router at a rate of between 270 and 300Mb/sec.

Before I began I read on the Ubuntu forums that many people had problems trying to get the thing to work. I found it was fairly straight forward which is probably a result of the new(ish) drivers on the edimax website for Linux.

You can download the latest source from http://www.ralinktech.com/ralink/Home/Support/Linux.html – I didn’t see any restrictions or licenses on there for the source, so I’ve decided to compile and upload the modules as I need them. You can check back here to pick up the latest if you’re not confident compiling it yourself.

Please don’t try running the modules on kernels that they are not for. This will not work! You will need to compile it against headers for your currently running kernel if you don’t find it listed here.

Date Kernel Download
1st Oct 2008 2.6.24-19-generic rt2860sta.ko.bz2

Then you’ll want to extract the kernel module:

bunzip2 rt2860sta.ko.bz2

Now test that it works before you continue:

sudo insmod rt2860sta.ko

Now run iwconfig to see if the module loaded OK. If so, you should have the ra0 device listed.

If all is well, copy the module to the kernel module directory:

sudo cp rt2860sta.ko /lib/modules/2.6.24-19-generic/ubuntu/net/rt2860/rt2860sta.ko

Now we’d like to tell it to auto-load upon system startup. We can do this by adding the line: rt82860sta to the /etc/modules file. Easy!

Update!!

I’ve recently found a link to a dynamically building kernel module .deb file, which is great because it means you can just install this .deb on your system and it should work. With a bit of luck the Ubuntu team will include the driver in Intrepid, but I wouldn’t hold your breath:

  1. Thanks, after searching the entire afternoon the .deb file did the job for me on the eee 901 (former xp)with intrepid ubuntu
