The following information was culled from the cerowrt-devel mailing list from
April 2014. I don't know if it's relevant for the current 3.10.36... versions,
so please update this list and then I'll publish it to the wiki.

------------------------
If wifi seems to hang using CeroWrt, please collect the following information:
1) CeroWrt version, Uptime, and other data. Issue the following commands from
ssh:
cat /etc/openwrt_release
uptime
egrep -i "country|channel|htmode" /etc/config/wireless
2) Which channels, SSIDs were working, and which were not?
- Was 2.4GHz working
- Was 5GHz working?
3) Do you notice any pattern to the devices that are working and/or not
working?
- OSX
- Windows
- Linux/Unix
- Android
- iOS devices
4) Log file symptoms:
what's in syslog? (What is the path to the syslog file?)
what other log files might be interesting?
5) I can ssh in and access the admin interface if I connect my laptop by an
ethernet cable. But during the failure, I can't access the admin
interface or the internet over sw00. After resetting sw00 by admin
interface on se00, I can connect over the wireless again.

7) What else should we check for?
