So presumably that device looks like an Ethernet to the operating
system. Are you capturing traffic to and from the machine on which
you're running Wireshark? If so, what OS are you running on that machine?
Could it be that I captured something that wasn�t meant for me due to
bad radio conditions?
Yes, that could be the problem, although I'd *expect* that if the packet
weren't received correctly some checksum/CRC at the GPRS, EDGE, or UMTS
layer would catch that, and the E220 wouldn't have supplied the packet
to the host in the first place.
Why are its fields so messed up?
If the packet wasn't received correctly over the air, that could cause
some fields to have the wrong values - but the Ethernet protocol type
field isn't messed up, which is a bit strange. It might be that the
adapter or the driver is constructing a fake Ethernet field, and is
assuming that *all* traffic is IP traffic, which might explain why the
Ethernet protocol type field is valid.
