Hello,

I bought a modem 4G “ZTE MF79U” but is not detected on my router GL-MT3000.

it shows these message in cellular: “No Modem device found. Plug in your USB modem to start.”

but it’s detected as usb Tethering, which it add double NAT!

could you please help to solve this issue?

Thanks!

tethering or modem mode depends on the modem’s Settings, you can ask the modem vendor if there is a way to switch.

there is no option on modem setting.
