[Windows Central Question]

When this happens, the phone has usually been on for some time, I have previously used the phone on this router within an hour, and our other lumia 635 does not seem to have this problem at the same time . . when I go to the wifi settings screen, the router does not show up as available. When I turn the phone off, and then restart the phone, the router shows up immediately, and at full strength, and the phone works fine, until it doesn't later in the day or the next . . .
