So I have a Dell Inspiron 8200 and it is about 6-7 years old. It used to connect to wi-fi just fine, now it detects none at all. I have done every thing I can with geeky computer mind but nothing seems to work. But I think now I need to update the driver for my built in wireless internet which is wlluc48.sys . But saying I have no internet connection to update it from and you have to pay to get it else where. How should I do this?
