Cellular Modem for Backup
(alien.top)
What's your phone signal like / Data allowance. If its good enough, you could use your phone as a backup wan connection using tethering. There is a cheap mikrotik device that will do it for your
Android phone with USB tethering worked fine for me using OPNsense, just selected it as a new interface.
Peplink makes a USB 5g modem that ??maybe?? works with pfSense, but my problem is that the router is in the basement & the modem needs to be upstairs to get a signal so I need ethernet
I use a pep link at work, solid device. Early adopter cost was high, we got one of the first 5g standalone modems on the market and spent a few grand. We also had to get a fancy antenna but it’s a solid system.
