It's the same problem cause I change txpower each time the card is inserted or 
the system is rebooted (I'm using that option in /etc/pcmcia/wireless.conf).

My card is the same as yours (Mikrotik 200mW) but it also happens with a Demarc 
100mW (both cards are Senao cards). I don't have a 30mW one just to test if 
it's a problem with the hostap driver while changing txpower or it's a problem 
with the high power itself (>30mW).

I'll try to debug it and I'll let you know what I discover.

Thanks a lot!!
