[ath9k-devel] Cannot disable power save mode on WLM200NX AR922X

[ath9k-devel] Cannot disable power save mode on WLM200NX AR922X

[Beat Meier]

Hello

After having no luck and no answer with my problems with ath5k driver
and mostly cards I use (bad throughput, bad signal) for
long distance links in 2.4GHz/5.8GHz I bought new WLM200NX cards
(AR922X) which use ath9k.
It works very nice for throughput! But I have a power sleep problem with
this cards
It fills me the syslog with the following messages:

[1198371.442029] ath1: STA 04:f0:21:06:20:b1 aid 1 exits power save mode
[1198371.442072] ath1: STA 04:f0:21:06:20:b1 aid 1 sending 0 filtered/0
PS frames since STA not sleeping anymore
[1198429.914624] ath1: STA 04:f0:21:06:20:b1 aid 1 enters power save mode
[1198429.918340] ath1: STA 04:f0:21:06:20:b1 aid 1: PS buffer for AC 2
[1198429.919472] ath1: STA 04:f0:21:06:20:b1 aid 1 exits power save mode

I see that power save mode is enabled,
iw dev ath1 get power_save
Power save: on

but try to disable power save mode fails
iw dev ath1 set power_save off
command failed: Operation not supported (-95)

try to settting results in no error, no output
iw dev ath1 set power_save on

By default power save is on on this card.

Is disabling not enabled or is this a bug?

Greetings a thanks

You don't disable power saving on the AP side. It's a STA side thing.
