S22 Ultra won't stay connected to AX WiFi 6

[Roland Smith]

I recently upgraded my home router to a Motorola MT8733 which has AX WiFi 6.

The phone is set to auto-connect but it won't and when I manually connect, it will disconnect after several minutes. This happens even when the phone is next to the router.

Phone is a Galaxy S22 Ultra model SM-S908U1.

First simple thing to try is to restart the router and then restart your phone, then see if it auto connects.

Both devices are up to date and have been restarted.
