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 Mode:Managed Access Point: Not-Associated Tx-Power=0 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off [root@R1 iw]# iwconfig wlan0 txpower 20 Error for wireless request "Set Tx Power" (8B26) : SET failed on device wlan0 ; Invalid argument.
