I look after a print farm of 6 ender 3s at my college. Right now, they all have an octoprint server each, from a raspberry pi on each printer. These are all connected to a network running on a router that isn't connected to the internet (as my college internet is enterprise and I couldn't get them connected to it).
I'm looking to connect them all to a network with internet access, and eventually unify them with an OctoFarm server on the same network. However, I have to use my own network separate from my college's and the only way I've thought of achieving this is through a 4G enabled modem. I tried one that was just lying around and it didn't work (however this wasn't an octoprint issue - it's always been patchy and is almost definitely a problem with the modem itself).
Overall, my question is this:
Is it possible to run octoprint servers on a WPA2 network broadcast by a 4G modem? If so, is OctoFarm also feasible? I just want to check before I make the investment in a working 4G modem.
6 Ender 3s, each connected by USB to a Pi 3B+.
