Debug log I have sent directly to you.

You. I'm on HT40- at primary 13 and secondary 9 because
other frequencies are totally in use.

I'm fully agree that follow described by standart rules is the right way. But
what I'm suppose to do? Why I should work at lower speeds because my dumb neighbors
even don't know what is WI-FI, they just know that "we have an internet without wire".
And I think that I'm not alone with such problem (at least in ex-USSR countries).
That's why I'm proposing to skip scan for neighboring BSSes configurable (and disabled by default).

Btw, I have notices that even AP works at 300mbps, after some time that fallback to 150mbps and
restore 300mbps only after hostapd restart. Maybe this is a problem of Win7 Intel Centrino drivers?
