protocol 0806 is buggy, dev usb0 !

[Markus Gothe]

Are you using the CWID / WebUI interface (I am pretty sure you are)??? Then I guess you are on your own.

You should use tcpdump or wireshark to disinsect the ARP packets and look in the kernel ARP-code for what is going wrong.

Try an earlier kernel and see what happens (or check the git changelog for neigh.c et. al).

Its clearly complaining about the ARP packets, the modem has some instability issues, not sure if thats related to this message. A googling doesnt give much info other than users reporting this once in a while - if anyone has more info about this please share, that will be of great help !
