Thanks for the report. That patch will be pushed upstream in a few minutes and 
will be backported to stable withing a few weeks. I am happy to hear that the 
patch works with your Alfa AWUS036NHR. In my limited testing with that device, 
it failed to connect. I feared that the RTL8192RU differed from the RTL8192CU.

I know that improper operation of the LEDs and screwy signal levels are 
annoying, and I will get to them when I can. At the moment, however, I have more 
important problems to solve.

Thanks,

Larry
