ath5k : Channel 149 thru 161 not working with compat-wireless-2.6.34.1

ath5k : Channel 149 thru 161 not working with compat-wireless-2.6.34.1

[Gopal Raman]

Hi
I have an internal ath5k (0x17AB:0x8331) NIC and with the old madwifi style
drivers (ath_pci ver 0.9.4.5) channels 149 thru 161 work fine. I'm able to rx/tx
frames.

With compat-wireless-2.6.34.1 running on 2.6.27.48 kernel, I can't receive (nor
tx) on channels 149 thru 161. The driver sets the channel without any errors.
But can't rx any frames. When I force transmit on these channels nothing is seen
on the air. Channels 36 thru 60 work fine

Is this a known issue ?

Thanks

Another piece of information is that when the channel is set to 149, 'cat
/proc/interrupts' hardly increments whereas on channel 36 it goes up
real fast. Also 'iw ph0 info' does show that channels 149 thru 161
in its output.

I found issues when switching to ath5k where the wrong antenna was selected.

Try forcing the antenna (especially if you don't have 1 of them
plugged in) and see how you go:

Hi
I could not find the sysfs node where antenna control is being set in the 
compat-wireless-2.6.34.1 driver. Maybe that was taken out ? To rule out 
problems with my NIC card can anyone confirm that with this driver we can 
receive frames on channels 149 thru 161 ?
Thanks much

Hi
I downloaded the latest compat-wireless snapshot and this time found the debug
node in the debugfs filesystem for the ath5k antenna. I set it to the 4 values
possible i.e "diversity", "fixed-a", "fixed-b" and "clear" but still can't
receive anything on channel 149.

Can someone confirm that they can see frames in channels 149 thru 161 ? If the
driver works on these channels, it must be something to do with my h/w

Thanks

It could also have to do with your regulatory domain -- check that as well.

I only have one 5ghz device, so I can't say whether it works for me or not.
