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=
