GL-SFT1200 with USB LTE modem

i have a GL-SFT1200 which works great tethered to my phone but wont recognise my LTE USB modem which is one of these.

the USB modem works fine plugged into my laptop where it just looks like a wired network connection.

I see this device has a WRT GUI where extra protocols can be installed but i’m not sure what i would need to add to try and get this working.

It’s possible that our router doesn’t have the driver for this USB dongle, or that the dongle isn’t operating in tethering mode.

You may consider purchasing our newly launched product instead.
