[Olsr-users] olsr not pinging in 2 hops

Hi,

the screenshot looks like there is a very high multicast packet loss
for your links. Maybe you can verify this with a multicast ping.

Run "ping -I wlan0 -b 255.255.255.255" on one node and look for the
incoming multicast pings with tcpdump on the other node. If the
multicast loss is too high, the routing protocol cannot work.

(hint for next time: its easier to copy/paste the text into an email
than to make a screenshot)
