My folks have a Windows XP system (fully patched) that recently stopped communicating with the local router.
Wired connectivity is as follows: Computer >> Router (Netgear WGR614v6) >> DSL Modem >> Internet
When they start up the computer, they (eventually) get a message that there is limited or no connectivity. The route shows positive link lights for everything.
So far, we've tried the following:
- Replacing cable between the computer and router lan port.
- Plug cable between the computer and router into a different lan port on the router.
- Replace router with an identical router with similar configurations.
- Releasing and renewing IP addresses (which returns an error about failing to communicate with DHCP server).
- Connecting DSL modem directly to router (same issue about limited connectivity).
- Specifying a static IP (which still prevents us from pinging the router).
- Changing speed/duplex on NIC from autonegotiate to 10 Mbps/HD.
- Disabling/enabling NIC.
Unfortunately, they don't have a secondary computer so I'm not able to easily confirm the computer as the cause of the issue. At this point though, it seems likely. Can someone please advise on what else we can do to troubleshoot here?
