These number look really bad. Looks like the wifi links between the nodes are 
basically not working. You can check the signal of the links via `iw dev wlan0 
station dump` but there is (most likely) nothing which can be done from the 
batman-adv side. First you have to fix your wifi links.

I have no idea what these LOGILINK WL0084B are using or how good they are 
(they look rather crappy regarding the antennas but please correct me).  If 
you want to try a different mode (in case Adhoc is broken in this driver) then 
you can try to use meshpoint (802.11s) without the routing enabled. I think 
this was done like this:

    iw phy phy0 interface add $MESH_IFACE type mp
    iw dev $MESH_IFACE set mesh_param mesh_ttl 1
    iw dev $MESH_IFACE set mesh_param mesh_fwding 0
    iw dev $MESH_IFACE mesh join $MESH_ID

Kind regards,
