EP06-E and not work DHCP in usbnet=1

Good day. I used Ep06-E complete with Mikrotik RBM33G in QCFG mode = “USBNET”, 1. Then AT commands, led the module to the fact that he stopped issuing a DHCP address for the lte interface (in the range 192.168.225.xx) in mikrotik. Separately, there is an interface lte, at startup it connects to the network, but there is no communication with the interface. In ppp-out mode it connects, there is a connection.

Nearby lies the second EP06-E module, comparing responses to AT commands, I do not see a difference in answers. The only difference is that in the USB device window, the working (second) module is called Quectel, the limited working one is called LTE-A. PID / VID are the same.

What do you advise ? How do AT commands return the modem to normal operation?

Dear Fog168,
Thanks for your inquiry in Quectel forums.
Could you help to provide the module firmware version or the exact AT command you used ? I have checked the command, cannot find “USBMODE”, Please help to double check it. From your description, you want to change the module network card type, if that you can try the command AT+QCFG=“USBNET”. Thanks!
