Huawei K5150 with GL-AX1800

Hello There,
I have this modem by Huawei.

When I connect this with Windows 10/11, it brings a Windows built-in interface, where I can put APN etc so connect. The interface is quite like wifi interface.

But when I use this modem with GL-AX1800 router, It seems like the router do not recognise this as a device. Can you please suggest how I can make use of this modem with my router?

This USB dongle does not support, please refer to this supported list:

It needs to configure the APN in its interface before use it. Means that driver for this device probably special (Not pure Modem/Module devices), required to debug and develop if connect to the OpenWRT OS to work.

Thanks a lot for your prompt reply. If I'm not wrong, this modem is MBIM supported modem and libmbim is also available. I was wondering how to make these work.

Google to see if this dongle has MBIM mode.
If MBIM or RNDIS (prefer) is supported, probably it will be easily adapted to the GL router.

Are you able to put it in hilink mode? aka hostless or tethering mode.

Mate, I am not too technical person but I can understand some things. If you check this post, the person made this modem work on raspberry pi using libmbim-utils.

Then I found libmbim is available for OpenWRT. Now I need someone to help me how to configure what and test if this is working.

Also came across this post, seems like rNDIS also works. Can you please provide a simplified guideline?

Please note, I would not use this device as my primary connection, this device will take over when internet is down, so I do not want to make any changes, where this will be my primary internet connection source.

Can you please suggest me how I can do that? I came across this post but as you already can understand I am not that expert.

Actually I don't know. I suppose that the Huawei program in your windows can configure the dongle. If they have such choice then pls just use that.

But generally the hilink version will have "h" in the model. Your K5150 seems not hilink but better have a check.
