Alfa AWUS036H Clone 500mW USB Txpower setting driving me crazy..
Hi...I am new to this forum..I hope someone knowledgeable can help me.. I have been trying for 4 days to set Txpower on an alfa AWU036H Clone ..It's a Palm 500mW usb adapter with RTL8187L chipset Txpower search this forum up and down with no results... I have used "iwlist wlan0 txpower...I received tx-power= 9dbm ..(7mw)..then I typed in "iwpriv wlan0 highpower 1" I then get an error that highpower is not a command...I tried "iwconfig wlan0 txpower 20" I get.."error for wireless request.."set tx power (8B26): set failed on device wlan0:Invalid argument"..??? so I tried "iwpriv wlan0" lists highpower as an available private ioctl. After the private protocols are displayed ..I am lost..What are the commands should I use?..I cant seem to change the Txpower level on this device..I would appreciate any help
