Sensitivity setting problem

Hi folks,

I've hit a really unforeseen problem. My father and me have upgraded
RF path and aerial of our AP. We've got really nice signal levels now.

And now my AP hears some distant noises which I absolutely don't
want to hear. AP is desperately trying to pick it up among legitimate
traffic of my STAs, frequently lowering their bit rate down from 11M.
8(

Also my logs are constantly filling with hostap whining about seeing
packets directed at 'wrong' ap mac addr. Thankfully I have rotating logs
and there is no risk of disk being filled with this junk,
but I must say I've set a personal record of log rotation angular velocity
today ;););)

You can see one second worth of this log below my sig.

I tried iwconfig wlan0 sens 1,2,3 but to no avail.
I presume that foreign signal exceeds threshold at any of these
settings.

I've read the code and it seems hostap does not accept any other
sens values. What can I do? I hate to think that I'll need to add
*attenuators* to the RF path 8( 8( 8(
