Intermittant WAN connection lost

[RCracer]

I have 2 computers connected to a Linksys BEFSR41 acting as DHCP, with a SB4100 cable modem. One computer is rock solid, no problems. One will occasionally lose the WAN connection: I can browse the network, but cannot access the internet or even the cable modem access page (192.168.100.1). This will happen several times per day. The problem goes away after re-booting. I have changed ports on the router with the same results. I have uninstalled and re-installed the NIC, though I don't see that (or its device driver) being the culprit as I have LAN access. I updated to the new beta Explorer, but still have the problem. I'm stumped, can anyone help?

How far away is the second computer to the Wireless Access Point?

This is a wired connection - CAT5

replace the wire. See if that's an easy fix.

I tried switching cables on the computers, it didn't help.
