Hey @jond and @akgwhiz - That is fine for work stuff, but I also have a lot of home automation, and of course, music and video streaming that goes on. To use a hotspot I have to re-configure each device independently to switch from the wired network to the hotspot. Certainly not really a workable solution for my fire alarms, thermostats, lights, etc. but I have done this to get my Roku working.
That’s why I’m going to attempt an automated, redundant, dual-Internet setup. I’ll put a Ubiquiti EdgeRouter before my home Wifi router, and that will connect to my two Internet modems. I hope.
