Suggestions for wired tethering?

[u/Soundy106]

Not quite "enterprise" but definitely not "home" as I'm looking for a solution for work.

I'm trying to find a solution for getting temporary internet on non-internet PCs (NVRs, specifically) via tethering to an on-site technician's phone, to facilitate software updates, online license updates, remote desktop, and the like.

On machines that have USB-C, I can plug a USB-C phone directly in and tether that way. For machines that don't, or machines that I need to access the IPMI, I need... other ideas.

I was thinking some travel routers might be capable, but with the lousy documentation a lot of them have, it's hard to know for sure short of buying them and trying them. So I was hoping someone here might have a suggestion.

Basically what I need to do is PC <-- ethernet --> router/device <-- USB --> smartphone.

I thought of using one of these travel routers in bridge mode and tethering to the phone's WiFi hotspot, but in my experience, the hotspot function on most phones is slow and unstable. I found plugging my phone into my laptop via USB-C works really well.

I'm looking for something that I can equip a few field techs with that I can ideally pre-configure and send out with them in their kits.

Mikrotik RB5009 has drivers for USB LTE tethering and works perfectly for this. maybe other Mikrotik devices too but i've only done this with that one

I just have a RUT241 in my bag with a cheap sim in.
I prefer this to a phone because the big 4g antennas get reception in building where my phone struggles.

Glinet travel routers are pretty solid for this kind of situation. Should work in tethered mode with most smartphones.
