Huawei E3372h-320 with GL-MT1300 Beryl?

Technical Support for Routers 4G LTE, 5G NR, USB modems

Hi all,
I’ve seen a few other topics about my issue, however the solutions did not work for me (yet).

I’m trying to use a Huawei E3372h-320 with my GL-MT1300 Beryl router. The dongle works on my laptop, however so far no luck with my Beryl (firmware 4.3.2 beta1).

What have I tried:

  • reset of dongle
  • change subnet of the Beryl from 192.168.8.1 to 192.168.7.1

What works:

  • dongle on laptop
  • tethering with a phone on the same SIM card
  • access 192.168.8.1 via Beryl (indicating the dongle is active on the router)

Any suggestions what I can try to get the LTE dongle working?

I’d keep the Beryl’s subnet to 7.1; it looks like the stick itself defaults to 192.168.8.1 in some sort of ‘router mode’.

Stick: This version is designed for the embedded Linux host devices (such as
gateways) for business customers, supporting interface specifications
designed in this document. The PnP feature in the preceding list is
applicable only when the USB stick is used on a PC running Windows (for
software updates via WebUI). When being applied to an embedded Linux
host device, the corresponding driver must be installed on the device in
advance.

Okay, so where does one get the Linux ‘drivers’ (in Linux parlance kernel modules aka kmods)? This looks promising:

HOWTO use a Huawei E3372 on OpenWRT

OpenWrt Linux is underlying OS that GL builds their GUI on. I’d consider downgrading to the stable firmware if any ‘strange’ issues start showing up… beta is beta for a reason, after all. YMMV.

An update on this question for the record:
As of Jan 2025, plugging a Huawei E3372 into a GL-MT1300 Beryl with the latest firmware just worked. No configuration necessary - it recognised the dongle and automatically used it for internet.
Sweet.

Is it a hilink (tethering) mode? This mode should always work out of the box.

My post was in response to the title, an OP saying that they couldn't get their huawei dongle working with their beryl router. I found this when researching which dongle to buy for my beryl, and as you say it now works out of the box.
