I think mayyyyybe that your router has to be reactivated after you execute a
'system restore.' I may not know what Im talking about, so just disregard
this if this doesnt make any sense. --But when you initially hooked the
router to your PC,(as per the instructions that came in the box) didnt you
have to go to a website and enter the model number and an activation code? I
seem to recall having to do that.
