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. 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. 2. None of the ports are listed in port list. 3. 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.
By using putty, connected to a COM port
Translated in modem mode, the command AT ^ SETPORT = “FF; 10,12”
Mikritik work, but using ppp-client
Speed does not rise 3.5 MB / sec
The Mode 3G works but LTE (4G) does not work
The same bandwidth limit issue on e3372 and MT RB912UAG-2HPnD, v6.20. In hilink mode testspeed.net to LMT (in LMT network) shows 50/30, in ppp-out mode 30/20. e3372 configured as 4G modem - AT^SETPORT=“FF;10,12”.
How do you switch between PPP-Mode and Hilink? I have the LMT Megafon 150-1 which is a Huawei 3272 and I would like to switch from Hilink/IP-Mode because I can’t see RSSI. Or is there any statistics available in /interface lte ?
Hello,
You can learn how to have solved this problem?
I have the same situation lte1 interface, mikrotik creates LTE interface But there’s no internet connections.
In LTE interface settings i cant get Info because “Could not start - Modem does not have serial interface! (6)”
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. 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”. Thats all.
Hi all! E3372 successfully works as a modem (PPP connection) in Evolved 3G (LTE) mode.
It brings 30 Mbps of internets but suffers up to 30% cpu load. Primarily cpu is loaded by ‘ethernet’ and ‘firewall’ subsystems on default-like router configuration due to profiler.
Is this load ok? Could it be better with LTE-interface (HiLink mode)? I don’t want to change modem firmware without a big need.
Hello, RB2011UAS-2HnD still seems to have problems with Huawei E3372 4G modems
it doesnt appear in resources/USB after i have connected it and no LTE interfaces appear,
tried all sorts of restarts and shutdown procedures listed in other threads to get it to detect the modem but with no luck
router has the latest 6.30.2 OS
Edit:
Got the modem detected through a hub but still cant get the LTE interface
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 http://workupload.com/file/NmOAD4pW)
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?)
I have the same problem.
Also have Hardware version: CL1E3372SM Ver.A
I sent already a supout file to support team but its saturday so you know..
Anyone know? Whats wrong
finaly got it made to have a connection via USB LTE Modem (PPP Mode … NOT HiLink)
big problem thou is, i have around only 50% of speed of my provider (Hutchinson 3G Austria 3AT)
normaly my speedtest results are around 40Mbit down / 15Mbit up when Huawei E3372 is connected to my mac
when i connect the E3372 to my routerboard (RB951G-2HnD) and i run a speedtest i only have 12-20Mbit down and around 6Mbit up…
i habe no QoS, Queue Limiting, etc. active
here some Huawei E3372h Info:
at^hcsq?
