I would be looking for a LTE USB stick supported by OpenWRT, the USB LTE Stick meant to provide the Internet connection, the OpenWRT router meant to provide firewall and WiFi to clients.
I know my way around on the OpenWRT side, but I am basically clueless on LTE support.
I have seen the wiki, but that does not seem to have specific USB LTE stick recommentations. The device list only seems to have all-in-one devices.
Can anyone e.g. name specific LTE usb stick models that are known to work with OpenWRT 21.02?
Or does someone have recommentation, for what to look for, when choosing between available LTE USB sticks?
Or should I rather look for proprietary LTE modem routers and attach the OpenWRT device via LAN?
