WiFi radio power settings can't be altered #9

Closed Lukse closed 11 years ago

Lukse commented 11 years ago

WiFi power settings can't be changed. It is not really clear what power level Carambola is operating at.

Formatting is a bit distorted, but looks still understandable.

Can you do the following and post strace output on this ticket:

When carambola is not connected to an AP:

wlan0     IEEE 802.11bgn  ESSID:off/any  
 Mode:Managed  Access Point: Not-Associated   Tx-Power=0 dBm   
 RTS thr:off   Fragment thr:off
 Encryption key:off
 Power Management:off

Changing TX power via iwconfig wlan0 txpower XX works just fine. iwconfig shows set value. So I am not sure there is any problems/
