Hi,I had the same problem. What I did was:
- Right clicked on My Network Places
- Rick clicked on the Networking connection and went to Properties
- Uninstalled each component one by one. After you remove a component, the computer will ask you to restart, click on 'NO'. For some reason, it wouldn't let me remove TCP/IP.
- Went to Device Manager and then uninstalled the network card.
Restart PC and it should redetect the card again. TCP/IP will still be installed from the previous attempt but the settings will all be defaulted.
