Started about a week ago with my laptop. Connection was, and still is, spotty. When I do a troubleshoot it sometimes fixes the problem and connects, but usually doesn't. Then, a day later it connects just fine, only to not connect again later. Seemingly no rhyme or reason. When troubleshooting doesn't fix it I get the message shown in the attached file.
I thought it was just my laptop, as the modem/router/network shows up just fine. I can theoretically connect to other networks in the neighborhood (didn't follow through, of course, but checked to see if it would), and all of them were found just fine. Plus, our blu-ray/netflix player and my wife's laptop all connected just fine.
Then, two days ago my wife's computer started doing it. Then, yesterday, the blu-ray/netflix player started doing it. Right now, as I write this, my laptop is connected and the other two devices aren't.
Nothing has changed regarding my modem and router (I have one of each) as far as location, set-up, etc.
