Using PPP interface, vendor-id='0x05c6' device-id='0x9000' LTE interface from R11e-LTE/R11e-LTE-US mini-pcie module

No serial support, but works with IP on LTE interface. LTE interface, Modem can be configured only through modems configuration WEB page. LTE interface with Ethernet emulation (no configuration possible), LTE supported bands 42/43 Ppp/LTE interface, there is page in wiki about Quectel: article Ppp/LTE interface, there is page in wiki about Quectel ppp mode: article

Ppp interface, there is page in wiki about Quectel: article Ppp interface, vendorid=0x1bc7 deviceid=0x1201 For ppp mode send AT^SETPORT='FF,12,1,16' data-channel=1 info-channel=0, other modes are explained in modems manual. Only cdc_ecm and Serial modems are supported. vendor-id='0x12d1' device-id='0x14dc' There is different versions of this modem available, not all work under RouterOS. Not supported in ROS v6, but as this modem supports MBIM drivers support will be possible in ROS v7. And starting with v7.xx it will support LTE interface. interface lte at-chat input='AT^CUSTFEATURE=3,1' To reduce LTE interface IP subnet mask to /32 configure modem with at-chat command: Recommended modem firmware version 11.617.24.00.00 No serial support, but works with IP on LTE interface Looks like only modem with device-id='0x14db' works as LTE interface. There are multiple versions of this modem. For some devices it's needed to enter in FACTORY mode to change operating state. If modem uses firmware 3.5 it should be upgraded to 3.5.23.2 firmware release in order to work in RouterOS correctly again. This article describes supported add-on peripherals for RouterBOARD hardware devices.
