I recently had someone over my house who brought an iPhone and iPad and gave her the passwords to connect to my wi-fi signal. But I also had my iPhone and iPad connected.
Three of the devices connected, but only after I unplugged the wi-fi router and replugged it. But I couldn't get her iPad (which is 1st gen) to connect to the Internet.
In fact I typically need to reset the router for her iPad to connect.So why is my router having this trouble? When I go to the nearby cafe, everyone's connected to the free wi-fi.So what gives?
