Hi & sorry for the late reply.
I can't use system restore NOR can I get windows updates anymore but that is another story...
My neighbor came over & fiddled with the laptop for awhile & finally managed to get intel proset re-enabled and everything is fine now.
I've had intermittent problems with my wireless router where I lose internet connection & the only way to fix that is to reboot the router but that wasn't the problem this time.
Anyway thanks for answering.
