So I’ve seen the TP-Link and GL.inet travel routers, and it looks like some of the GLs are/were built to run wrt firmwares. Stock TP firmwares have been pretty full features in my experience. I really want USB-C power. The GL wireguard support looks useful too, but it looks like their newer stuff is proprietary? Another want, not need, is 5 GHz band.
Does anyone have a favorite model or another board that can be flashed?
You can get a C-to-micro adapter if that will work for your use case and you have a micro-USB router that you like.
