This may or may not help on txpower control.

 From I gather on the power control there are a few things Id like to 
know as well ... txpower was taken out of the hostap distribution + 
thrown into a patch:

http://www.jikos.cz/~jbohac/hostap/

However I just flashed my card from 1.4.9 to 1.7.9 
(http://linux.junsun.net/intersil-prism/firmware/) without looking over 
that page a bit more carefully ...

All testing and debugging I have done so far was on 1.5.6, so this is 
what I recommend. I don't have time nor hardware to test with different 
versions.

People also reported that with 1.7.4 a and 1.8.0 the txpower restore did 
not work. Again ... use 1.5.6 :) Update: on Jan 22 2004 I flashed my 
cards to 1.7.4, and the patch really doesn't work. I will try to fix it 
in the future.

Is it "safe" to downgrade the firmware using prism2_sec?

Thanks.
