Over the last week the family pc running Vista has starting showing a second public network when there is only 1. I usally got around it by merging it with the other network but it will not let me do it anymore.
Setting an alternate IP for IPV4 under Alternate in properties for the adapter.
Changing both to public/Private +merging to no avail.
Uninstall the LAN Adapter (via device manager) +reboot
Changed router (to one i knew worked before)
Disabling all services bar microsoft via MSCONFIG
Ran IPCONFIG/ALL but seen nothing amiss,proper IPV6/4 address/subnet/DNS/Default Gateway etc
I havent tried updating hte LAN Adapter Driver
as the same driver worked well with the older router.
