E3372h-320 USB/lte1 problems constantly LTE1 link up-down

Hardware MikroTik hardware general

Hello.

Please help. Huawei E3372h-320 LTE USB Stick is constantly logging in and out and is therefore non-functional. Is there any solution please ??
I also tried an active USB-2 HUB - it didn’t help.

Here is an extract from the log after turning on the RB:

Thank you very much for your help.

I have the same stick, and it does the same thing. When you look at the USB resources, it’s flipping between USB storage device and LTE modem. I think it’s trying to offer its builtin ‘driver CD’ flash to the Mikrotik, like it does to Windows machines (where it works fine) on first connect, and the 'Tik can’t deal with that.

But I haven’t been able to make it stop and just function as an LTE modem. If anyone has been able to get it to work, I’d be very interested as well!

What RouterBOARD are you using?

Regards.

Same behavior on a hAP AC and a CCR1036-8G-2S+. The hAP is at 6.46.4 and the CCR at 6.46.1.

6

and what firmware & webui version you use at e3372 ?

WebUI:

Software version 10.0.3.1(H192SP1C983)
Web UI version WEBUI 10.0.3.1(W13SP2C7110)

Firmware: 22.001.34.01.03

Hello.
So I tried to use version 7.0beta8 and everything is OK !!! The web interface with settings and sending of SMS is even functional. Fast download test - 70 Mbit / s. So for me - solved :laughing: :laughing: :laughing:

10

That’s good news! Time to upgrade my CCR to 7.0 then…

11

Same buggy behavior on E3372h-320 with Mikrotik
Modem:
10.0.3.1(H192SP2C983)
WEBUI 10.0.3.1(W13SP1C7702)

Mikrotik:
Factory Firmware 6.44,
Current Firmware 6.45.3
After upgrade to 6.47 not working too :frowning:

On Linux Gnome 3.36 all working fine

you have a lte1 flapping interface.
Please check when lte1 is down if usb device is still detected in system \ resource \ usb ?
You use HiLink mode with dhcp-client at lte1 then what show you his GUI when you connect to him ? Means, uptime and session uptime or maybe you have some custom firmware ?

In all my e3372 I reflash the firmware at versions 22.333.01.00.00 with 17.100.18.03.143 but this is my responsibility to do that staff go grab features like DMZ, Change LAN IP and have API for SMS… I not know versions of firmware.

13

Like I said earlier, when the link is flapping it’s alternating between two USB IDs in USB resources, one for a storage device and one for an LTE modem. When in ‘modem’ mode the link is up, when in ‘storage’ mode it’s down.

It probably needs an MBIM driver to function (which is what gets installed as a service under Windows when you install the drivers off the internal ‘driver CD’ flash in the unit). It works under RouterOS 7beta8 (which does have MBIM drivers, whereas ROS6 does not), as both @Jirka69 and myself have tested.

14

Then please do a supout.rif with that situation and send them to MikroTik support.

15

I’ve experiencing same issue as described above.
hAP ac 6.47 (stable)
Huawei E3272h identified as:
0x12d1
0x14db/0x1f01
Upgrade to beta version is not a solution for me.

16

Then do the same, contact to MikroTik Support.

17

Already done :wink: Thank You.

18

Any feedback from Mikrotik support?
Just bought hap ac lite and the same problem.
Looking and System->Resources->USB the modem disappear when lte1 is down and appear in few seconds again.
My assumption is that the problem with USB Power, but I don’t know how to check it.
Very upset if this is the case as I just sold my RB951Ui-2HnD (where it was 500mA on USB) because of the same issue and by recommendation from other posts acquired hap ac lite (where it is promised to be 1A).
Hence I would be grateful if someone found the root cause and how to fix it.

19

Feedback from Mikrotik not very very helpful :slight_smile:
Multiple messages about diagnosis.
They advise me to upgrade to beta (7) version of OS .
I’ll try it but first I have to read about fall-back procedure.

I have the same stick, and it does the same. With 6.x it flips between two USB IDs, that of a 4G stick and that of a mass storage device, and the link is up when it behaves as a 4G modem.

Upgrading to ROS 7beta8 worked for me connected to a hAP ac.
