I have an Acer C720 connected to AT&T internet with strong-signal wi-fi. About 30 minutes after I boot the computer and experience trouble-free internet usage, I start getting "cannot connect" messages for every URL that I enter. The connection status bar has all 4 bars when this happens (still connect to wi-fi router). This does not happen to any other device in our household (3 computer, 3 kindles, one smart TV), so I don't think it's an AT&T problem. Usually when this happens, my computer is the only one accessing the internet at the time.
Any ideas about how to solve this problem?
