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?
