Good afternoon everyone, hope your all good,

This is my first post and with a bit of luck, someone will be able to assist as V.M's technical support is crap!!!

Basically the problem is as follows. We have an older style NTL:Home cable modem that is normally connected to a Linksys WRT54GS wireless router which then connects 3 pc's hardwired via ethernet cable, which upto yesterday, worked fine. We have received a new Virgin Media Cable modem (the smaller blue one) which we've plugged in and are now having problems with one of the pc's.

When the modem is connected to the router, 2 pc's connect to the internet without any problem. Our 3rd desktop pc is having major problems though. Having checked in the network and sharing centre LAN status / details, no IPv4 default gateway is being acquired from the modem. I've connected this cable modem directly to the Ethernet port on the pc that isn't working and bypassed the Linksys router completely, re-booted both PC and Cable modem, and still no IPv4 IP address. I've connected the Cable modem to a laptop, and the laptop finds an IPv4 default gateway address without problem and connects to the internet. So, you would assume then that the problem lies with the pc. I've updated all the motherboard drivers including the ethernet and LAN drivers, and the pc says that the two LAN ports on the back of the pc are working properly.

I've also powered down the pc and modem and disconnected the co-ax cable, powered everything back up and checked checked the IP address which was 169.254.220.247, re-connected the co-ax cable, powered everything down and back up again, and still get the same IPv4 IP address.

The other 2 pc's that work when the modem is connected to the Linksys router are running WinXP and WinVista 32bit Home. The only difference with the pc that won't work, is that it's running WinVista 64bit Ulitmate.

I can't figure this out and am at the point of tearing my hair out. The tech guys at V.M. have said they will check to see if the MAC address of the router has been used twice on their system, said they'd call me back in 5 mins, that was 4 hours ago!!! The router by the way is registered on V.M's system so that shouldn't be an issue.

Any help or ideas would be most appreciated. Hope your all enjoying the sunshine.

Kind regards.
