hi jara!
are you sure it has to do with the upgrade from compat-wireless-2010-06-13 to
compat-wireless-2010-06-18? i don't see any relevant differences in the code
between these two versions...
it might be interresting to see what results you get from noise calibration.
you can enable calibration debugging with "echo calib >
/sys/kernel/debug/ath5k/phy0/debug"
