Hi,
The AR9285 is a 2GHz only NIC.
The channel list shows 11b, 11bg, HT20 and HT40 channels.
It all looks right, why don't you think it is?

Compile and run athstats, it'll tell you how many aggregate frames are being
sent and received.

I was confused that there is no mention n-mode in the output channel list

Well it would be much clearer to understand by changing the output of
the the channel list to show 11b, 11bg, 11n20 and 11n40 channels instead
of HT20 and HT40, so people would readily know n-mode was active. HT has
no meaning to the general user.
