[ath9k-devel] ath9k_htc Stops Responding After Period of Time (at91rm9200 processor)

[ath9k-devel] ath9k_htc Stops Responding After Period of Time (at91rm9200 processor)

[Aaron Hamilton]

I'm using an ath9k_htc (ZCN-722M/0cf3:9271) as an AP and after several
hours of use, client devices can no longer attach. When everything stops
working, there's no indication whatsoever in the log.

If I restart hostapd, everything seems to work fine for a while, but then
stops working again.

I'm currently using backports-3.12.8-1 with a 2.6.39.4 kernel and a simple
hostapd config (see attached config files).

Am I missing something or should I be using a different version of
something?

You might be hitting the 8 clients limit of that hardware+firmware

check out iw wlanX station dump when the issue happens, and see if you 
already have 7 clients associated.

cheers!

[Kyle Bassett]

Hi Gui,

Can you elaborate on the 8 clients limit?

[ath9k-devel] ath9k_htc Stops Responding After Period of Time (at91rm9200 processor)

[Adrian Chadd]

There's only enough space in RAM in the NIC to store state for 8
associated clients.

There's been talk about dumbing down the firmware in the NIC so it
doesn't do much more than be a data conduit and handle basic retries,
so this limit wouldn't be hit. but it'd be a reasonably thorough
rearchitecture of the driver and firmware.

[ath9k-devel] ath9k_htc Stops Responding After Period of Time (at91rm9200 processor)

[Aaron Hamilton]

Tried iw wlan0 station dump and it came back with nothing. Also, we
only have three devices configured at the moment to be able to
associate with the AP.  Also, I forgot to attach dmesg previously.
I'm assuming the message "ath: phy0: FATAL Event received, resetting
device" might have something to do with it?

May be firmware related issue.
Please use firmware from latest git and newest wireless code. There are
lots of changes, including patch which will log information about FW oops.

[ath9k-devel] ath9k_htc Stops Responding After Period of Time (at91rm9200 processor)

[Aaron Hamilton]

I'm currently using the latest firmware from
https://github.com/qca/open-ath9k-htc-firmware, but it appears
backports v3.13.2-1 and newer are missing mac80211 and ath9k_htc
drivers. At least when I do make menuconfig, they are not available?

Scratch that. I just checked backports-20140320 and it allows mac80211
and ath9k_htc to come up.

[ath9k-devel] ath9k_htc Stops Responding After Period of Time (at91rm9200 processor)

[Aaron Hamilton]

Looks like both backports-20140320 and 3.14-1 fail to compile with the
error ".../backport-include/linux/compat.h:18 error: expected ';', ','
or ')' before '*' token?  Could this be caused by my kernel config?

I can't help you here. take a look at /backport-include/linux/compat.h:18
Or try contact some one from backport team.
