There are now quite a few options for wifi APs with cellular backup. I use TP-Link, and it's ok for the price, I guess, and supports adding OneMesh range extenders.

The problem with this setup for me is that it doesn't work with uplink that sometimes becomes unstable yet nominally working, and in general LTE fallback triggers slowly.

Are there any prosumer-friendly options for connection bundling, which can balance uplinks continuously?
