No wifi adaptor found

Hi everyone, been sometime seen my last visit.
Just loaded current zorin 17.1 on my workshop pc, which is a older Quad core Intel.
Installed OK. all hardware recognised, then updated my apps and finally downloaded nvida drivers. clicked on the restart button and now i am told i have no wifi adaptor found. this happened in 2 separate machines with different wifi cards.
Dont know how the wifi driver relates to restarting after installing nvida driver.
I cant go on line in the workshop without the wifi.
Please any help appreciated.
