Hi Andreas,

just to be sure we're suffering the same thing: have you had a working
connection as well or do you always just solely outgoing packets?

For me it seems to be related to signal quality: in case of good
quality I do get packets in both directions in case of poor signal
strength it's only outgoing.

Cheers,
Stefan
