They are in http://wifi.one-b.it/download/

I have disabled eth0.0 (batman only on interface wl0) on node2 and
same behavior: after a while route to node6 disappear.

I make another test with only 3 nodes: node2 with one interface (wl0),
node6 and node3



node2 (10.1.1.1) ------ node6 (10.1.1.33)
          \
           \--- node3 (10.1.1.10)

After 2 minutes with "batmand -g 0 -r 2 -d 1 wl0" on all 3 nodes:

node2
10.1.1.10             10.1.1.10 ( 67):       10.1.1.10 ( 67)
10.1.1.33             10.1.1.33 ( 21):       10.1.1.33 ( 21)

node6
10.1.1.10              10.1.1.1 ( 66):        10.1.1.1 ( 66)
10.1.1.1               10.1.1.1 (120):        10.1.1.1 (120)

node3
10.1.1.33              10.1.1.1 ( 20):        10.1.1.1 ( 20)
10.1.1.1               10.1.1.1 (121):        10.1.1.1 (121)

I suspect that batman does not hear some packets, maybe for wireless problems?
