No Internet after Windows 7 Professional 64bit Update

This is the second Windows 7 - 64 bit machine where after a Windows Update, the Network Card stops connecting to Internet. Only way to fix it is to uninstall and reinstall the Network Card. Of course have updated to latest drivers from manufacturer, but last time had to just buy a network PCI card to get around the problem of no Internet connection and keep a reliable remote connection.
Of course, uninstalling and reinstalling the Network card will not do when accessing the machine remotely.
Trying to identify the update which is causing this, whether is a security update or what so I can remove it. Tired of reinstalling Windows to resolve same problem.

 

Tried a simple System Restore instead?
