Trying to figure that one out. Will have an in depth response by the end of the week. With standard Linux it is quite easy to do so: http://goo.gl/gtfhB at least with BackTrack anyway. Code: Select All Error for wireless request "Set Tx Power" (8B26) SET failed on device wlan1 ; Invalid argument
I noticed with rtl8187l it's loading r8187l module which is why we have no injection and why we prob can't change tx power.
