RBR750

Thank you both for your quick replies. Yes, the MyQ is a camera for a garage supplied by Chamberlain. My RBR750 is on the “latest” firmware version V4.6.14.3. My modem is an ATT  U-verse Modem. The key point is that for couple of plus years the camera worked fine. I spent an hour and a half with a MyQ technical support person and tried to reset it and reinstalled it many times. It was able to get connect to my WiFi but got hung up on a last step of renaming the camera. A separate support person told me that they have a firmware issue with the camera and it is it my WiFi. Still not working, I called again and got the message that I listed. (My network knowledge is novice at best).

Then I read both your replies and after reading that my WiFi should be able to handle the protocols, I decided to try a reinstall again. I brought the camera closer to my router upstairs (although the signal strength is excellent in the garage), deleted it from my Bluetooth list and went through the install process.….And behold - it worked. I unplugged the device and reconnected it in the garage and it still WORKED. Hurray.

So problem SOLVED, thanks to you two, but I don’t know why. The mystery if WiFi!?
Thank you again!
