Es-tu Tobias de tai?

Hi all,

i have setup a mesh-network with batman-adv running on about 10 Foneras
and 4 TP-Link on OpenWRT.

At first everything seemed to work. A node on the one end could ping a
node on the other end over the mesh-network. The ping was hopping from
node to node as expected.

But sometimes some paths do not work anymore.

Some nodes can only reach their direct neighbors via a "normal ping". A
ping to a node via one hop does not work. A "batctl ping" does work!

This only happens to parts of the network and is not permanent. If i
wait it will recover, but then the problem appears at another node.

dmesg or the syslog does not report any errors.

Can anyone give me a hint where to look?

Tobias
