I asked this question because not long ago I had a problem with TCP
connections hanging and I was sure that all packets should pass the
firewall because of rules like those you mentioned. But when I added
a logging rule, I discovered that packets were actually rejected. (The
cause was a lousy router that mangled packets in way violating an RFC,
and in the end I had to disable the SACK option).
So I thought that maybe your "crap wifi network" had also a crap
router mangling packets in some way or another. But this is unlikely,
if you don't have a firewall on your local machine, and you say you
experience problems with any other machine:

No other clues, sorry. :-(
