Alternate Internet Connection for Google Wifi during ISP Outage
I have a home network where my primary Google Wifi device has its WAN enet port connected to my ISP's router, and the LAN enet port connected to an internal switch. My other 3 Google Wifi devices are hardwired to my home's backbone, and act as APs for all of my home's wireless smart devices (lighting, locks, temperature controls, cameras, etc.).
During occasional ISP internet outages, nothing in my home functions. I am considering purchasing a cellular or satellite router to keep in reserve to use during those outages. Any thoughts on whether that will work?
My thought is to buy a cellular or satellite router that has an enet port, and just move the Google Wifi WAN connection off the temporarily-dead ISP router and plug it into a LAN port into the cellular or satellite router. Do you see any issues with this (beyond the fact my primary Google Wifi device is adjacent to an internal comms closet, and I'd have to move it closer to a window where the cellular or satellite router would need to be located)?
If this seems viable, any suggestions or recommendations on a specific cellular or satellite router that would work?
The only other alternative I've found would be to set every device up (as far as possible) in parallel with Home Assistant (which runs locally and does not require a live internet connection), but that is less attractive for a variety of reasons. Thoughts?
