I was poking around for a USB C 5G/LTE modem that I can run either off my laptop or plug into my router as a secondary WAN. Has anyone messed with something like this?
The secondary WAN is common, but I usually need some sort of DC power input instead of a single USB C cable that I can put into my laptop.
GL.iNet travel routers would like to have a word with you.
They have multiple versions available.
I’ve used GLinet but I find I have to power cycle them every day or so to keep working. Otherwise they’re cheap and workable. Probably wouldn’t trust them as a backup link.
I looked into this about a year ago. Most of the mobile modems I came across require DC power, or were far too expensive to be practical.
What I ended up doing was buying a used android phone hooked up to a mobile router.
It’s also doable to use a DC to USB adapter, depending on the modem’s power draw. Make sure the device falls within the power delivery specs for the cable you’re using though
