I have a strange problem that has been driving me mad for over a month, and would appreciate anyone's advice on the matter.
Here's the current configuration:
ISP: TPG, static IP
Modem/Router: NetComm NB5Plus4
OS: Windows XP SP2 (windows firewall disabled)
Zonealarm firewall, McAfee anti-virus
My problem is that one of the two computers on the network will intermittantly lose it's internet connection. I can access the modem's menu through the Browser (Firefox and IE are equally affected), but can't see the other computer of the internet. When the internet is lost during a session, the IP address stay router assigned, other times its the Windows default 169.x.x.x
Windows repair connection universally says "unable to refresh IP address".
ipconfig /release then /renew will sometimes reassign the IP, but rarely restores connection. The only thing that sometimes work is to reboot and hope.
Here's the bind:
I've just moved house, it was happening at both houses. Different ISPs each time.
I have another computer on the network with the exact same software setup, it's been fine the whole time. The only difference is that the affect computer is newer (Intel C2D E6750, 2Gb DDR2 vs Intel Cerelon D 768Mb DDR).
It doesn't matter if I use a PCI network card, the MB inbuilt adaptor or USB connection - all are affected the same.
If anyone has any suggestions, I'd love to hear them. I've searched solutions but nothing has worked so far. If you need any more specifications, let me know.
Thanks for the quick responses.
Sarvjit: rj11 wire has been changed a couple of times, between using different modems. And why would only one computer be affected if this cable was the issue. I've scanned before, but another time can't hurt, I'll try that.
Roleo: All computers are set up to obtain their IP from the router's DHCP.
