Hello Gioacchino,

I'd say that losing packets is not normal :-)
Have you tried to use batctl td on the wired interface? You should see the
"broadcast" packets going around. It would be interesting to understand if on
batctl you had more packets than what you are receiving on the node.

Cheers,


p.s. what kind of hello messages are they? Their size is changing over time..
