Here are the steps I followed to update the wifi drivers on my Efika MX Smarttop to support packet injection under kernel 2.6.31.14.27-efikamx. This also seemed to provide better connection stability. Should also work for Ubuntu.

Install packages: The kernel headers package is missing a directory required to build compat-wireless, so we need to clone the kernel source from git and hackily rectify the problem: Grab and build the latest compat-wireless rtx200 drivers from http://linuxwireless.org/download/compat-wireless-2.6/ .. I used compat-wireless-2012-05-10 .. Your mileage will vary depending on which version you choose. Now you must blacklist the old rt2870sta driver so it does not load on boot Reboot the machine and you will be using the new driver. Works as a normal wireless client, with aircrack-ng, reaver, etc.

If you are running the same kernel I am, and would like to skip most of the above, download the binaries I have built from http://www.slingfile.com/file/UjvSGas83X . Copy the 'updates' directory to /lib/modules/`uname -r`, run depmod -a, and blacklist the old module.

Great, but in my case it keeps complaining about firmware.

"Failed to request firmware".

Ofc I have the firmware files on /lib/firmware, tested with two revisions, the 8Kb one is working on another machine (not an Efika) with a USB dongle, and the both work with rt2870sta.

Could you post your firmware or at least its MD5 hash and the exact location and name?

EDIT: The problem was that compat-wireless uses an udev script that didn't get installed neither is distributed with your binary package.

Hi, You might be better off using my debian package instead you can read about it in this thread here:

http://www.powerdeveloper.org/forums/vi ... f=7&t=2278

I also have the packaging on github at https://github.com/wschaub/compat-wireless

the armel version might well work on maverick as well as on Squeeze but I haven't tested it on maverick. My pacakge does install the udev rule and the firmware loader script that is missing above. you can also find the missing bits at https://github.com/wschaub/compat-wirel ... re_install <-- script that installs the udev stuff

https://github.com/wschaub/compat-wirel ... aster/udev <-- where the udev rules and scripts are located.

In case anyone that is running maverick is interested the package does work on maverick. but you need to have linux-image-2.6.31.14.27-efikamx installed (which you can find here: http://steubentech.com/~talon/Efika-MX/kernels/latest/)

Too late! :p

I suggest a wiki with tips and tricks!

Already wrote it. I have an article at http://library.powerdeveloper.net/index ... atWireless
ready now.
