MB50 Trouble


First time post (no need to be gentle).
My MB50 worked fine before I left town, three days later when I returned it had dropped the wifi and now won't restore.
I have tried factory reset and have toggled network sleep and standby mode.
I have deleted and reinstalled play-fi app on three different devices (2 ios, 1 windows). 
Unplugged everything, and rebooted wifi router.
No matter what I do, the wi/fi light flashes rapid green and won't go into the pulse mode, and the playfi device does not who up in the available networks.
I would be very appreciative if anyone has experienced this or other similar issues, and if so, how they cured.
Thank you.
