Hi Steve,

you can use "batctl log" to retrieve the log. It will not appear in your 
logread.

When the problem happens, you can also check "iw wlan0 station dump" and other 
debug files (batctl n for neighbors) to find out if the WiFi layer is still 
working. It wouldn't be the first time that actually the WiFi chip or driver 
has a problem, not batman-adv.

Cheers,
      Simon
