My mistake. I have now posted the message on the Windows 7 forum
I have a desk top computer, a lap top (Asus model K53E), and a tablet. I have no trouble connecting the desk top and tablet to the internet through my wifi router. But, as of yesterday, the lap top will not connect. I plugged the lap directly into my modum and it still would not connect. It runs Windows 7. I ran the Microsoft diagnostic program. No problems detected. Any suggestions on what to do next?
