Orbi RBR20 connectivity issues after upgrade to V2.6.2.104

We have had flawless performance from the Orbi RBR20 since we bought it.

I upgraded the firmware last week and now we need to reset the router 1 or 2 times per day due to Internet connection issues.

Devices can connect and communicate with the router but nothing on the far side of the router is reachable.

The router reports everything is fine.

Turning the router off, and then on resolves the issue, but this is not something I want to be doing a couple times each day.
