Hey,
we have trouble with an AR9330 (Hornet) based AP. This device has 2 antennas,
and is supposed to support diversity (2 RX, 1 TX). However, diversity is not
really enabled because the "alternative" antenna is not considered as "good",
because not enough frames are received. It seems that at
Hey Shafi,
we had this checked out before, the EEPROM/EEP_ANT_DIV_CTL1 value is set to

debug enabled.
The symptoms are the same as described before. I'm pasting part of the syslog

ath9k fellows,
as it seems no one could find the cause for this problem so far. I'd therefore
like to create a workaround by checking one/some registers for 0xdeadbeef and
reset the chip if this is found.
Can anyone recommend a register which should never go 0xdeadbeef in a normal
case?

Add spectral_scan function to driver functions, and hook it up
in the scanning code.
Using the spectral scan from within the scan function has the charme
that it already does all the channel surfing for us.

We were doing performance tests with various 2-stream 802.11n clients, but
