To finish this thread, I want to record what was done to get this working.
If you notice any omissions or errors please correct or let me know and I will do the correction.
Kernel in use for this build
D-Link DWA-125 A3
Downloaded from: http://www.ralinktech.com/en/04_support/support.php?sn=501
Note: The driver name that comes down is "2011_ .... _DPO.bz2" and should be renamed as above.
Extract the driver into its own folder.
In the 2011_0719_RT3070_RT3370_RT5370_RT5372_Linux_STA_V184.108.40.206_DPO/os/linux/config.mk
file do the following edits
Enter folder 2011_0719_RT3070_RT3370_RT5370_RT5372_Linux_STA_V220.127.116.11_DPO
In a terminal as user, domake
[ignore this error: cp: cannot create regular file `/tftpboot': Permission denied]
When done dogzip -9 ./os/linux/rt5370sta.ko
su to root, then do the following four commandscp ./os/linux/rt5370sta.ko.gz /lib/modules/`uname -r`/kernel/drivers/net/usb/
Next do depmod -a
and thencp RT2870STA.dat /etc/Wireless/RT2870STA/RT2870STA.dat
Then run wpa_supplicant -Dwext -ira0 -c /etc/wpa_supplicant.conf -d
I believe the above is the order I did the commands.
Maybe there is a better order for a couple of them.
