Huawei Mobile WiFi E5573 LTE modem tested and works as LTE interface with RouterBoard RB751U-2HnD with RouterOS 6.41rc52 (USB connected).
The modem starts with Microtik when power come back and everything seems to work. I did not tested it with older RouterOS, sorry.
No special setup needed. Just DHCP client on lte1 interface and NAT in firewall.
This not mentioned under https://wiki.mikrotik.com/wiki/Manual:Peripherals so I wrote about my working setup here.
There is E5573s-320 number/code under the battery too along just E5573 mark.

Sorry for bringing up an old topic. I see the wiki lists some other MIFI devices, so I’m hoping this one still works with ROS. Does the DHCP client on the LTE interface receive an IP within E5573’s local network, or do you get a sort of bridge mode when connecting the MIFI device via USB?
that device should be detected as lte1 interface.
You can just create dhcp-client at lte1 interface and have hope that you receive addressation - if not then you can enable dhcp logs and grab new supout.rif and send it to support@mikrotik.com .
Sorry but at this forum is very small answers about this device, not every emulate ethernet connection, sometimes that lte1 must be disable/enable to start communication etc… different devices means different problems.
