Windows XP SP2 and router

[Frank]

I have 4 pc's that were updated with Win XP SP2. All pc's
connect to the internet via router (Linksys model
BEFSR41 - router with 4 port switch - not wireless) and
through a cable modem. After downloading SP2 and applied
to all pc's, I loose internet connection (time varies
from 3 minutes to an hour), however, if I connect the pc
directly to the cable modem, I do not loose conectivity.
The error messahe I get in the Local Area Network status
window is "limited or no connectivity". Spent endless
hours with Linksys support team and got nowhere. Any
ideas of what may be wrong please e-mail me directly at
(e-mail address removed). Thanks

Are you using a firewall? If so, which one? It sounds like it's not
configured properly.
