My pc I haven't wifi and hotespot

hey, it depends to your windows version, actually in lower version of windows like 7 some drivers like wifi and hotspot is not install and then we have the same as your problem to solve that you need to download your wifi driver its easy to find just search model of your computer and type wireless driver at the end, if your looking for easy way or cant find the driver you can install some apps to find it like IObit.Driver.Booster or driver talent and after that you can install them, if your computer doesnt works after this process again maybe its hardware problem you need to change your wifi card in your computer
