Okay,
Have you checked with router mfr website for updated firmware? Make
sure your computer static IP address is unique from the other 3
computers. If you assign a static IP outside the range of reserved
DHCP addresses, you'll minimize the risk of duplicate IPs
Some troubleshooting thoughts.
If you do have 3 other computers that are working on this router and
the one that does not, the problem is probably one of the following:
1. NIC on your PC
2. Network Cable between your computer and the router. (Does the light
that corresponds to the router port you are using light up when
plugged in?)
3. Bad port on the router.
4. Firewall
5. Your router is not compatible with Vista 64 (not likely)
First, does the link light on the network adapter on your PC light
up?
If not,
First plug the cable into one of the ports on the router that you
know works.
Then, click start/run/cmd <enter> (run as administrator)
then run these 2 commands: IPCONFIG /RELEASE, THEN IPCONFIG /
RENEW
If that works, you found the problem - bad port on the
router.
If not,
Run a different cable that you know works from your computer to
the router.
If that works, you found the problem - bad cable.
Anytime you make a port change or cable change, run the 2 ipconfig
commands above just to be starting with a fresh lease.
Look at the exceptions tab in the Windows Firewall and be sure the
routing and remote access is checked. Look at the other items and see
if any others might need to be checked.
Sorry I'm scattered, hectic morning,
