myq hub green light is on but no wifi signal
I have a Linear opener and Droid smartphone. This was working properly, but whenever I went to my Chamberlain app it would report e.g.: that the garage door was shut for 11 hours when I had just opened it. So I went to reconfigure. I pressed setup button on hub. Solid blue light came on. The MyQ-xxx wifi connection network did not show up. I went to Manage Networks on my smartphone. The MyQ-xxx network is Not in range. Well, I'm standing next to the hub, so there's no good reason for it to be out of range. I have unplugged the hub and plugged it in again, to no avail. This is frustrating beyond redemption. Thanks in advance for any help you can provide.
