Hello.
I'm having some sort of a problem with RT3070 usb dongle. It works
perfectly fine under 3.3.5 and 3.3.7 kernels, but somewhy refuses to
set txpower under 3.4.0. kernel .config is the same across all three.
Here's some output:
[root@R1 iw]# ifconfig wlan0 up
[root@R1 iw]# iwconfig wlan0
wlan0 IEEE 802.11bgn ESSID:off/any

[root@R1 iw]# iwconfig wlan0 txpower 20

[root@R1 iw]# iwconfig wlan0 txpower 1
