Suddenly unable to network

[austinpctech]

I have a Windows 2000 system that is suddenly unable to connect through a
Linksys router which is connected to a cable modem. Other computers connect
to the router ok. If I eliminate the router by plugging directly into the
cable modem I can connect to the Internet.

Thanks for any help you may offer.

I am getting the following errors at bootup:

Either the cable is bad, or the port on the Linksys Device is bad or you are
using a "Crossover" cable when you should be using a "Straight-Through"
cable.

this may help, quoted from http://www.ChicagoTech.net

Can't obtain/renew IP addresses from the DHCP server
Symptoms: 1) you have a DHCP client which may not be able to obtain/renew IP addresses from the DHCP server intermittently. 2) after setup a workstation to obtain an IP address from DHCP, the machine can't ping others and ipconfig /all shows Autoconfiguration IP Address. . . : 169.254.x.x.

Resolutions: 1) If this is XP, obtain the latest service pack for Windows XP.
2) Use the Network Diagnostics tool to identify any failed settings. To do this, go to Help and Support>Use Tools to view your computer information and diagnose problems>Network Diagnostics>Scan your system. When the process finishes, check for any items marked "FAILED" in red, expand those categories, and view the additional details about what the testing showed.
3) Assign a static ip on the client and ping the DHCP server. If you can't ping the DHCP server, check the connection and hardware.
4) If you can ping the DHCP after assigning static ip, check the DHCP settings.
5) Make sure no firewall is running on your LAN.
6) Run Repair this connection if it is XP. Or use netsh to reset TCP/IP configuration.
7) If it is win98/w2k, remove and reinstall TCP/IP.
8) Try to upgrade the new NIC driver.
9) Make sure you don't run out of IPs in the DHCP scope.
10) If you use a router as DHCP, you may want to upgrade the firmware.

Either the cable is bad, or the port on the Linksys Device is bad or you are
using a "Crossover" cable when you should be using a "Straight-Through"
cable.

I have tried using different ports and cables but get the same result.
Other computers connect fine to all ports on the router.

This means it does not connect to the Linksys Device at all, it is failing
to get its address from the DHCP Service running on the Linksys
box,...hence,..the reason it is getting the APIA Address as described above
in the "decription". If the cables are good, are the proper type, they are
all seated properly, and all ports on the Linksys box are good,..then the
Nic has gone bad in the machine.
