So, there has been a new kernel release from Genesi - 2.6.31.12-ER1-efikamx.

On Gentoo, you download the 51mb 2.6.31-ER1-efikamx lzmaball, and then the patch.

extract both - since on a Gentoo machine, it is fairly standard to have the kernel in /usr/src/linux - thats where I extracted the files. Then I moved the patches into the linux-2.6.31.12-ER1-efikamx directory (renamed from 2.6.31-ER1-efikamx) and then created a symlink.

Make the kernel as per norm (by default when you apply the patches, it copies the Genesi config file to .config) editing the config whichever way you prefer to add/remove options, and build it.

Don't forget to mount /dev/sda1 before you make modules_install!

Now we download the driver from Ralink for the RT3070 - 2009_1110_RT3070_Linux_STA_v2.1.2.0.tar.bz2 (sorry, no direct link as they do request you accept the license) - extract it wherever.

Go into the 2009_1110_RT3070_Linux_STA_v2.1.2.0 directory, and then edit os/linux/config.mk

Change HAS_WPA_SUPPLICANT=n to HAS_WPA_SUPPLICANT=y
change HAS_NATIVE_WPA_SUPPLICANT=n to HAS_NATIVE_WPA_SUPPLICANT=y

make

Wait a bit - then delete /tftpboot (Ralink's makefile copies the driver to there)
Then copy the module somewhere in /lib/modules/2.6.31.12-ER1-efikamx (I like to use /extras or /networking) then blacklist all the in-kernel wifi stuff in

/etc/modprobe.d/blacklist.conf

blacklist rt3070sta
blacklist rt2870sta
blacklist rt2800usb
blacklist rt2x00usb
blacklist rt2x00lib
blacklist mac80211
blacklist cfg80211


and then in /etc/modules.autoload.d

add "rt3070sta" (as I'm writing this, yes I see that I'm blacklisting it and then explicitly autoloading it - will fix later)

Don't forget to run depmod -a

Reboot!

Now you need to edit your RT3070STA.dat file - this will reside in /etc/Wireless/RT3070STA/

When playing with wpa_supplicant, you want to have it run non-daemonized while trying to debug it - by default, on the Efika MX you will run it with the following command:

wpa_supplicant -Dwext -Ira0 -c/etc/wpa_supplicant/wpa_supplicant.conf

(Note: the location of wpa_supplicant.conf may be different if you aren't on Gentoo)

If you are on Gentoo and using the stable "arm" keyword, then you may want to go into /etc/conf.d/net and set

modules_ra0=( "!iwconfig" )


So that it will use wpa_supplicant rather than trying to set everything up manually with iwconfig.
