Disappearing Ethernet Connection

[Walby]

hi,
After upgrading my operating system (windows xp to vista) Checking under devices, no network adapter shown. Just disappeared.No sound problems after the upgrade, but I lost my Ethernet connections somehow.Tried swapping cables to and from the router, no effect.Does anyone know what causes this issue and how to fix it?Any help will be extremely appreciated.

what you need to do is go into device manager again

• click -->View -> Show hidden devices
  
• open up network cards
  
• look for the ethernet card there
  
• right click it, uninstall it
  
• right click my computer at the top of device manager
  
• scan for new hardware
  
• should find your card now

hi,
the card will remain enabled if a network cable gets connected.There are two ways to overcome this setting, firstly, go to Control Panel,and look for Internal NIC Configuration or use the Quick Set software. Let us know if this resolves your issue.

Did your computer/motherboard come with a CD. You will probably find the drivers there.

Otherwise downlaod and run Everest. . This will tell you exactly what kind of NICs you have and you then download the drivers.
