I have two wifi networks in the office, one hooked up to a cable which is unmetered and one to a cellular net which is metered. The idea is to provide a redundant network connections should one go down.
I can hook up both networks to the relevant servers (obviously there are modems that bridge onto the wifi networks). But what I want to do is prioritize so that all traffic goes through the cabled network and the cellular network is only used if the cable network is down. The goal is to have the cellular bridged network as a back up. The idea is that all the computers that actually need this level of redundancy have a couple of USB->WiFi devices plugged in.
All devices are Windows 10 systems.
This seems to be something that a lot of people would want to do but short of some ridiculously expensive equipment from CISCO I'm not sure how it can be done. It is surely possible simply in the network stack software, but I cannot find how to configure it.
Anybody got any suggestions?
