We have a mesh network running on an adhoc wifi network. All the nodes are in static position. The problem is that when one node goes down, the mesh breaks and the bat0 interfaces of the nodes are not reachable (although, strangely, the nodes are reachable via the wlan0 interfaces). Also, the node that has gone down is in one corner of the mesh.
When one of the nodes is down,
