A thought ... I've seen some genuine squirrelies myself ... when I
setup wifi on our machines, I make it a point (Verizoff is our DSL here,
and they're AWFUL) to add mtu 1468 in my ifconfig settings. I forget what
the default for wifi is, something on the order of 2290 or some such, and
it's not a valid MTU at all. Give that a shot, that's what it sounds like
to me. Wired ETH does the proper 1500, but the wifi default in BSD 8 is
just not right ...<br><br>

But if I start any other network traffic, say an ftp transfer, then the
response time skyrockets and the transfer rate reflects this:<br><br>

I'm running 8-STABLE and using the iwn driver with an Intel 4965agn
card. This problem only happens over wireless and is not an issue
when using a hard wired connection.<br><br>
