USB Tethering with GL-MT300N-V2

Technical Support for Routers
1

Recently purchased a GL-MT300N-V2, have updated to latest firmware.

Connected via USB to a Galaxy S9 running on Android 10 security version 1 April 2020

On the GUI I get the notification for USB0 to connect, click onto it and nothing happens just spins.

I have tried plugging the phone into laptop directly and USB tethering works perfectly, have tried 3 USB cables from cheap to expensive and even the genuine Samsung cable.

Tried my sim in an old Galaxy S8 and that works fine.

Tried Two Galaxy S9 and a Galaxy S10 all on the same firmware version and none of them work.

Any advice please?

Hi,

Hold on. Seems we found the problem. It should be the same as S10.

We will have a 3.104 firmware for MT300N-V2 solving this issue. Pls hold on a moment.

Thanks, will it be available for auto update or will I need a manual firmware file?

I am an S9+ user. I have tried 3.102 and 3.104 firmware for MT300N-V2 and they both can internet with tethering normally. However, I cannot change the method of USB directly from the control panel. I need to change it from setting.
Maybe this is the bug of Samsung mobile phone.

Hello, I’m having exactly the same problem with a Samsung Galaxy S9+ on Android 10 !
I even went and bought a cheap usb 2.0 cable to try with it and still nothing … the connect button spins for a moment a nothing happens …
Tried with the last firmware and the testing one too. Issue not fixed.

I just tested the USB tethering on a Samsung S21(5G) with android 11. The tethering works fine with Mango（Firmware V3.105）here is the download link: GL.iNet download center
But I must tell you guys, make sure your USB cable is a cable that can transfer data with samsung smartphone because I tried 3 USB cables, only one can work with android smartphone data transfer, so you can select connection method (charge only, USB tethering etc…) in the notification bar.
