I recently had Windows Update offer me a driver update for my video card.  
Except it turned out that it was actually for a different model, also made 
by ATI, and was not in fact fully compatible with the hardware in my 
machine.
  When I went to the video card entry in Device Manager and checked its 
properties, I found a button (on the Driver tab, I think) that said 
something like "Revert to previous driver"; clicking it caused the name of 
the device to revert to its previous setting and I once more had a working 
display.
  Is there something similar on the modem entry?
