That's what I'm getting. Attached are two tcpdump -w files, one from 3.5 and
one from CURRENT, detailing the transaction between the router and lynx.
Firefox transactions are similar, but much more cluttered. Notice especially
that the packet which should be sending authorization code is truncated in
(Yes, I know it looks like there's sensitive information in the tcpdumps.

My router doesn't use frames, and I can't determine why the packet seems to be
problem, but can't be sure.
