I just updated my Nvidia drivers to the latest set and since the update my network is totally wiped out. To beging the process I uninstalled the old driver and was very careful to remove only display drivers as I have Nvidia drivers for network adapters etc. When I rebooted I have no connectivity and cannot even repair the connection as I get the message that "IP address cannot be assigned". Worse still system restore will not restore ot any of the three points I have today or the checkpoints over the last few days either. Any ideas on a way forward?
