Hello, Recently i bought LMT (Latvijas mobilais telefons) 4G modem Huawei E3372 with SIM. With PC it works without any problems but with mikrotik RouterBOARD 951Ui 2HnD and with mikrotik mAP 2n it has problems.

Auto connection to available type of supported network (4G/3G/2G). Of the router with every modification of the firmware of USB modems. 3G/4G USB Adapter Compatibility List for ASUS wireless routers and DSL modem routers The following list details 3G/4G USB adapter models tested and recommended for guaranteed compatibility of all ASUS Wi-Fi routers and DSL modem routers except for WL-520gU, RT-N13U (hardware version A1, B1), DSL-N12U (hardware version A1) and RT-AC1200.

With Huawei E392 that SIM is working despite that E392 also isn't in supported hardware list. So what happens - 1. After inserting E3372 4G modem in mikrotik usb jack, mikrotik creates LTE interface, after setting APN and PIN in LTE settings 4G modem starts up (still blue LED) and it shows that it is connected/active. But there's no internet connections.

None of the ports are listed in port list. In LTE interface settings i cant get Info because 'Couldn't start - Modem does not have serial interface! (6)' After 4G modem pulling out and reinserting LTE settings are default (APN and PIN are default). About 4G modem: Device name: E3372 My number: Unknown Hardware version: CL1E3372SM Ver.A Software version: 22.286.03.00.17 I would appreciate if someone could tell what to do to make E3372 4G modem working.

Hello everyone, based on the facts I discovered here I bought RB951 Ui and Huawei 3372 modem. Both modem and the router work OK together, until I start downloading/uploading using wireless at maximum speed that the mobile provider allows.

After a short while normally after downloading some 250 MB, the modem disconnects and won´t re-establish the connection unless I reboot the router. I discovered that this problem manifested repeatedly at a peak of what the mobile network is capable of, usally cca at 23 MB/s(download), so I tried to limit the speed by the means of queue set at 15/15Mbits/s.

This seemed to help, however I encountered the problem again after a short while even with the limit set to work. I would like to ask if any of you have the same problem or an idea as to how to solve this? Thank you and forgive my inexperience, but than again, where else but here to ask for help. I've succesfully connected E3372 LTE modem to my Mikrotik 951Ui-2HnD - The modem must be hi-link version (modem acts as ethernet router). When modem is connected to usb port mikrotik creates LTE interface. You dont have to enter any APN, passwords etc because its all already configued inside LTE modem.

Ibexpert 64 bit.

Then You have to go to IP > 'DHCP Client' menu and click '+' to add new client for LTE interface. Then go to IP > Firewall and in NAT tab you have to make sure that masquerade chain is set to 'Out interface: LTE'. Works fine on 6.30.2 with lmt labeled huawei on hilink software. Exists e3372s or 3372h versions. Both must have the hilink software. But if the e3372 is in ppp modem modus lte reachs only 30 mpbs. In NCM-Modus it reaches full lte speed as its sector delivers.

It is possibil in next releases to implement this solution. Under lte tab it shows then the lte device in NCM-Modus when connected and acts as a Huawei-eth interface (its to implements the linux drivers ) trought a dhcplient on interface Huawei-eth is get assigned the pubblic ip. I have an E3372h-153 (T-mobile Hungary) modem ndis-ppp firmware, which did not work at first because of the need of usb modeswitch. I could fix the problem using the AT^SETPORT command. The original mode was: AT^SETPORT='A1,A2;12,1,16,A1,A2' I set the modem to: AT^SETPORT='FF;12,1,16' usb power reset, and it started working as a PPP interface.

------ I found theese settings using AT^SETPORT, and AT^GETPORTNAME: AT^SETPORT='initial_mode;normal_mode' map: 1 - Mobile Data Modem (MDM) 5 - GPS interface 6 - control interface 12 - PC UI 10 - modem? 16 - NDIS A1 - Virtual cd A2 - TF card reader FF - Dummy (disable modeswitch when using this as the initial mode?).
