Losing TCP/ IP connection with server

[Don]

I'm constantly losing IP connection with internet server and mail server.
Opening the Network Connections and using the repair function to clear and
reassign IP and DNS seems to be a temporary fix.
Could some one give me the logical steps to analyze and fix the problem.

Using a Cable broadband connection from Linksys WRT54G Broadband Router to
Realtek RTL8169/8110 Family Gigabit Ethernet NIC
* Installed SP2
* All LAN connection setting same as before
* Turned off the WindowsXP firewall since and WRT54G firmware has Firewall

* Ran McAfee VirusScan and Sypbot [no problems found]

* Updated Realtek RTL8169/8110 Family Gigabit Ethernet NIC diver
* Updated firmware for Linksys WRT54G Broadband Router
* Installed new Terayon Cable Modem and updated firmware

When you have the problem, do you still have an IP, etc., in ipconfig /all?
Can you ping the servers by IP address? Ping the router's LAN IP?
Tried forcing your NIC speed to something other than autosense?
