Hello Marek,

i needed to get this working so i switched to 2011.2 last weekend and 
the problems are gone.

So it seems it's a bug introduced in 2011.3.

The network on which i had the problems is live and in use, so i can't 
make any further tests on it right now.

I have some similar devices as spare parts. I'll try to set them up and 
reproduce the problems - but that can take a while.

What i can tell you is:
- every node has only one wlan-network on which batman runs and only the 
node itself uses the bat0 interface - no bridging, no routing
- at the end, most of the time only the directly connected nodes were 
reachable via a normal ping - the "hopping" was not working
- i had the *feeling* that the problems got bigger the more nodes we added
- also i *think* the problems began when we mixed Fonera- and 
TP-Link-devices (sightly different architecture i think)
- the log was always spammed with messages - because of the tiny devices 
i use it's not easy to save the log and inspect it when the connection 
is working again - which can take an hour...

Thank you for your help. I'm sorry, that i can't provide you more infos 
to track down the bug.

Tobias
