Lost network connections with Vista

Every time I reboot or shut down and restart my computer Vista loses the
network connection. Diagnose and repair reports back the IP and DNS needs to
be re-established. When I tell it to obtain the addresses it creates a
“second� network connection, which it then tells me I need to disable.
Disabling one disables both so the next step is re-enabling the card. After
re-enabling the card Vista refreshes the settings again, once more creating a
“second� network connection that needs to be disabled, starting the cycle
over again.
After repeating this process several times a single network connection will
final be established and everything works great until I need to shut down or
reboot and the process starts all over.

Any ideas?

I’m running an HP system with an on-board nVida network controller connected
to a Linksys router.

Assuming you have latest firmware for the router and driver for NIC, you may
try to disable IPv6. This how may help.

Thanks, that seems to work so far.
