I'v got a RB953GS 5HPnT and a modem quectel EP06-E. All the settings were made just like were taped pins and disabled "Ignore DirectIP Modem" from system->port->Firmware.
It is correct! The lte-intarface was appeared (with DHCP and defualt route).
Also I can send and receive SMS messages TO and FROM Mikrotik by this modem.
BUT it doesn't ping 8.8.8.8 under any conditions. I don't have any idias. Please, нelp solve this problem.
P.S. I apply screenshots
Yours faithfully.
