First of all, it's been a long time since I delved into networking so bear with me. My internet connection here is pretty unreliable (comcast), and recently was going out 1-2 days / month for up to 24-48 hours at a time. Typically it was stupid things like the maintenance tech screwing with something and not putting it back right, or rain causing issues. Anyway, I picked up a cellular wifi hotspot and was wanting to use it as a backup in case the main internet connection goes down, and then switch back to the main internet line once it's back up. Does anyone know what this would be called or how to set it up? I haven't come across a whole lot online but I'm probably just searching for the wrong terms. I just have a basic netgear orbi router setup connected to a few switches that then connect to my computers, but I have a beagleboard black lying around and could setup a new router if necessary I guess.
