I have the hiccups

Hi,

I recently switched from using a DSL modem on one PC to running the DSL
through a Cisco 678 router into a Belkin access point, which is hard
wired to my pc's network card (Win2k Pro) and connects to my laptop (XP
Pro) via a wireless signal.

Ever since I made this change, I get 30 second-hiccups in my internet
connection on both machines about every 10-15 minutes. This becomes
really annoying when I'm using FTP or Terminal Services, because the
stutter is long enough to break the connections and interrupt my work.

Any idea what could be causing this? Is it some kind of firewall
"security" feature? It's so regular, I think it might be a purposeful
hiccup, but I'd like to turn it off, if possible.

The only firewall I have running is whatever was built-in to the Belkin
and I'm running different virus software on each machine, so that
probably isn't an issue.

Thanks.
