Hello,

I’m trying to use Huawei e3372h modem in stick mode with my GL-AX1800 router. The modem is detected, but when I press connect in AUTO mode nothing happens. In manual mode I can connect in 3G only mode. I’m trying to configure LTE as desctibed here [GL-AR750S with Huawei 3372h-607 in stick mode - #2 by limbot](https://forum.gl-inet.com/t/gl-ar750s-with-huawei-3372h-607-in-stick-mode/8839/2) but I can not install comgt-ncm package because it’s not found. What can be done to correctly install this modem?

OpenWrt 21.02-SNAPSHOT r16399+157-c67509efd7  
Kernel Version 4.4.60

Huawei have to use ncm protocol.

Can you try in Luci, install luci-proto-ncm

Find the modem interface and change proto to ncm

I have this package **luci-proto-ncm** in repository, but can’t install. It depends on **comgt-mcm**

Compile firmware for AXT1800 to support ncm now. Pls allow a few days.

Can you try this firmware which added support for ncm?

It should configure the modem automatically (ncm is not added in the UI but it will be used automatically for huawei modem).

Thanks for quick responce. I’ve tried you software, but it didn’t help. Now it’s trying to start but fails in the end.

Can you confirm your SIM card is OK?

Yes, SIM card if OK. When I insert this USB modem in another router - it works fine. On the Internet status page the IMEI and phone number displayes correctly. And with your firmware I notised that LED indicator on this modem becomes solid green, as it should when it’s connected. But on the router modem status is **Connecting** all the time.

Nothing to add here, but I’m watching this thread with great interest and hopefully others too. An updated firmware solution that “just works” with Huawei stick modems would be great.

Yes, 3G works fine when I go to Manual mode and choose 3G and port ttyUSB1. When I try to switch to NCM and choose ttyUSB1 port, it can’t connect. Attaching the log:

I noticed that you choose ttyUSB1 for ncm. Please use ttyUSB0 or use auto connect.

I’ve tried ttyUSB1 because in 3G mode only ttyUSB1 works. Now I’ve checked in NCM auto - the result is the same - it didn’t work. Logs are the same that I’ve send you earlier.

Did you use it on another router with NCM protocol?
