Maybe you have some similar problem as I, e.g. either an antenna diversity problem and/or an ANI problem.
If your WLAN device has several antennas and the wrong input is selected, then the driver is deaf. Moving away this little from the AP might get you disconnected then. If your WLAN device detects too much noise (or the noise detection is buggy), then ANI (adaptive noise immunity) attenuates the incoming signal. Again you get a bit deaf. But this time by purpose, so that the reception part of the WLAN chip doesn't get overdriven and into clipping mode. ANI can be disabled, one of the ath9k-modules (afaik ath9k_hw) has a disable_ani= command line parameter. Also, you can turn on ANI debugging to get a bit of output from ANI with specifing debug=0x40 to the ath9k.ko module. Note that increasing your own txpower doesn't help against a deaf reception. -- http://www.holgerschurig.de _______________________________________________ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel
