Hello,
I have been unable to connect to my wifi on my laptop. I am currently using my moms laptop I know there are 3 wifi hotspots around my house. None of the hotspots show up in my network sharing, yet I'm connected to one of them right now using a dif laptop.... So I'm just confused please help !!!!
