Vista has 169.254.x.x IP

I would try to disable the IPv6 first.

Hi, I have had a similar problem which took over a week to locate.

My situation was that I was connecting ok then suddenly Vista could
not access the DHCP server in the router.
Symptoms Unidentilied network IP addres 169.x.x.x.
I tried changing cables, ports, modem. All failed
What was strange was that the only way that I could connect was if I
had another device connected, - Old computer Nas Disk.
If I then cycled the power on the Modem\Router Vista connected.


The problem turned out to be a 3rd party Firewall.
It was OK until it was updated.The update changed something that
caused the problem
When I uninstalled the firewall the problem disappeared.

I hope this helps
