My father has his computer connected to a router which is then connected to his modem and has been having difficulties getting onto basic internet websites. He unplugged the router to restart it and forgot about it. Then he tried to access the internet and it is running smoothly...while still connected to an unplugged router. How can this be? And How do we get the wireless connection back without screwing up the desktop connection? In addition, the desktop computer says that it has no connection and that a network cable is unplugged.
