every so often i get a "device timeout" warning, but what really irks me, a
file starts downloading, and it just hangs..............................
nothing happens at all, with fetch, with firefox, etc.  i've found the
problem only exists for a transfer of a single file, ie, if i have all sorts
of internet activity there is no problem.

example situation:
fetch x.y
5% done (hangs indefinately)

in another terminal, if i type in "ping google.com" and either it starts
pinging, and the transfer starts again, or nothing happens, then i get ath
device timeout, ping again, and it starts up,  if the only internet activity
is fetch and ping, stopping ping will often stop the transfer.  i lots of
(continuous) small internet activity in order to keep any transfer going.

ath on 5.4 has some weirdness as well, but not like this
