Hi,

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

ok.

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.

Understood. We hopefully come up with a patch soon that will need to be 
tested.

- 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)

Can you tell us what TP-Link model you are using (name, hardware revision, 
etc). Or post the output of /proc/cpuinfo ?

- 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...

It is somewhat troublesome that the problem went away after a while. If we 
have a bug in the architecture handling you would expect it to be a permanent 
problem. But who knows ...

Marek
