I FOUND THE ANSER< the CLUE, the TIP THAT WORKS!
Having problems as you all and posted it, along with working WITH apple reps and their programming teams till they did not respond and emails returned...but found the key.
THis and ONLY this method works and steps skipped didn’t;
from POWER OFF:
1) Turn power on in keypad position and log into wifi
2: POWER DOWN (not turn off/sleep)
3) REPOWER UP again with keypad in position and log into WiFi if not logged in and should work.
when i did not log into wifi at first and just did the powering off and on it doesn’t work but have to log in twice.
after a year of problems with them and many visits, this is the only thing that’s worked but ...it’s not ideal and APPLE, you need to fix this!
