Called Chamberlin’s tech support and after walking me through the steps they said it’s the routers fault.

There may be some truth to that, due to default settings. Not sure if the Chamberlain device requires UPnP enabled, but newer (read: more secure) systems may have that disabled by default.

Mine worked with cablemodem + separate Asus routers.

Did not work with new AT&T fiberoptic modem with integrated router.

Works with T-Mobile 5G Arcadyan modem/router.

I use the very old (2014) Chamberlain Internet Gateway device.
