W98 Internet Connectivity Issues

I have a Windows 98 SE machine that is on a P2P network and connects to the
internet via a Cable/DLS router. The system was working fine until we
shifted some resources around.

Now the system can only get on the internet and browse the network
intermittently. When it does it is very slow.

I figured out what the problem is but not sure how to resolve it. The issue
is that when I ping another machine on the network either by static IP or
NetBIOS or ping an internet site server by either IP address or FQDN, I get
intermittent reply’s mixed in with requests timed out.

I get good consistent reply from the loop back IP 127.0.0.1 and I have
tested the cable with a tester and another machine. I reset the router and
cable modem, disabled the Norton Internet Security, cleaned out all Temp and
Internet Temp files, cookies etc. Ran Spybot and Ad Aware and the system
comes up clean.

I have verified that the IP stack is set correctly and compared it with
other machines on the network that work fine.

Does anyone have any suggestions on how to resolve this one?

Thanks - Jody
