Hi all,

I've been trying to debug this for quite a while with little success.

It seems that the AR9344 (2.4GHz side only) on the WD N600 routers is
rather unstable. At random intervals, the 2.4GHz side of things
completely stops passing traffic.

Stations remain associated, however no data is processed.

My Android devices show the network as ok - but no network connectivity.
I cannot ping the router, nor access the luci interface.

If I use the same device and connect to the 5GHz side of the device, I
can access things fine. I am unable to switch back to the 2.4GHz side of
the AP once disconnected.

Some of the time, using 'wifi down && wifi up' will restore connectivity
on the 2.4GHz side, other times I need to do a full restart of the device.

There are no obvious messages in dmesg or logread that would point to a
hang or certain module / device not responding anymore.

Currently running:
root@OpenWrt:~# cat /proc/version
Linux version 3.10.13 (openwrt@openwrt) (gcc version 4.6.4
(OpenWrt/Linaro GCC 4.6-2013.05 r38259) ) #2 Thu Oct 10 20:25:10 EDT 2013

Device info:

I have heard multiple reports from other people - enough that this seems
to be a common problem with this device / driver / something.

Does anyone have any suggestions on this?
