Problem is not with the router but the wireless adapter inside the
Acer.  Check for updated drivers from Acer or try uninstalling
wireless adapter and rebooting XP.  This should reset the drivers for
the wireless adapter.

You may want to contact Belkin for help.

Some third-party programs may experience a change in functionality after you
install Windows XP Service Pack 3

The above article has contact info for various vendors but none for Belkin...go
figure.

I Googled and found a firmware update that's available for your router, but you
should check with their tech support first to see if this will cure your
problem. Here's the link for the update:

Good luck!

Hi Paul,

I'm losing connectivity -- I use a wireless Netgear adapter -- to the
Internet after installing SP3, although it hasn't been immediately apparent.

Earlier this week, I first thought it was due to AVG 7.5 / AVG 8.0 issues.

However, overnight I lost connectivity again for no apparent reason, and
after spending an hour this morning uninstalling/reinstalling AVG and the
Netgear software -- and still being unable to get Internet connectivity as
it looks...
and looks...and looks to acquire an IP address -- I finally just uninstalled
SP3.

I'll continue using SP2 for a while.
