Problem GL-MT300N with LTE Modem Huawei E3372

Ah, shoot, it’s not your eye-sight, but my bird-brain… I have a AR300M.

alzhao · June 26, 2017, 3:17pm

AR300M firmware v2.26 has been released. Please upgrade and try again.

Sorry to say, but I habe the same issue: GL-MT300A with newest firmware 2.264 and my Huawei E3372 is not detected by the device (IP address is different between router and stick). The stick is working directly connected to my notebook or to another mini openwrt router (TP-Link, but with poor performance).

The GL-MT300A router is detecting the Huawei stick (according the kernel log):

The stick is detected with an ethernet device (MAC 0c:5b:8f:27:9a:64) and this is also the MAC address of interface eth1 on the router, but the interface is down.

So, I think this is an issue of the router or driver issues of the OpenWRT distribution.

Any useful hints at least from GL.iNet?

McNail

The modems is recognized but cannot get an IP address. Don’t know why.

I have to ask you to upgrade but there is a firmware v2.27 now.

McNail · June 8, 2018, 11:03am

I tried to upgrade to v2.27 but now I can’t access the router anymore Wether with its old IP address nor the last I had configured. And a reset with the button also doesn’t help to access it again.

McNail · June 8, 2018, 5:21pm

I’ve managed it now to flash again the router with v2.27 and can access it again. But with no success to detect the Huawei stick

SIM card is inserted in the Huawei stick, but the router doesn’t brings up the eth1 interface. According the kernel logs, the device is detected correct. But it seems to me, that the 3G modem detecting of the Huawei stick is a little bit better then the firmware before, but at least it doesn’t work at all.

Here are my log messages:

From the Log the modem is not recognized correctly. Maybe a new model again.

McNail · June 11, 2018, 10:45am

I bought the HUAWEI E3372 last year in summer, so it is nearly a year old. So it shouldn’t be too new?

McNail · June 24, 2018, 7:17pm

It seem that Huawei has different versions of this a stick: E3372 H-153 , E3372 S-154, E3372h-607 (maybe more?) And only one version is working with the GL-MT300N (and with OpenWRT). Unfortunately I don’t know which variante is my stick

glitch · June 25, 2018, 7:02am

Presumably you looked under the tethering tab and not 3/4G.
I believe the model number can be found if you remove the SIM and look there.

McNail · June 25, 2018, 5:35pm

ok, thanks for the hint. It is a E3372h-153 Huawei LTE stick. Maybe it could be interesting if somebody with another E3372 version could check if the stick is working

glitch · June 26, 2018, 7:26am

I believe it works, just you need to change the GL Lan to something else from 192.168.8.1

McNail · June 26, 2018, 11:02am

That’s only one part of the problem. But if you change the LAN settings to something other, the LTE modem (or stick) is not detected. As I wrote before: There are existing different versions of the Huawei E3372 stick. And some version will work and others not!

Old_Shaky · October 2, 2018, 11:14pm

A bit late to the party but I figured it.
You need to use a 2A USB power supply and a good quality cable. The cables that come with mobile phones are often too high resistance (due to the thin conductors) to power the router and tha attached dongle.

alzhao · October 3, 2018, 10:13am

Thanks for reporting back.

So which ID were you using?

Azndfc · May 4, 2020, 5:00am

I changed the GL Lan to something else from 192.168.8.10 (another IP than 192.168.8.1)

But

I still can’t access the E3372 hilink modem status from 192.168.8.1 after using tether from tethering tab.
But tethering works perfectly.

Why?

I’m using GL-AR150

Powered by LuCI openwrt-18.06 branch (git-18.196.56128-9112198) / OpenWrt 18.06.1 r7258-5eb055306f

Please advise
Thanks in advance.

Azndfc · May 4, 2020, 6:14am

changed the lan ip address to different prefix than good ol’ 192.168. and it works!!

alzhao · May 4, 2020, 10:50am

Yes you need to change to another subnet if Huawei is using 192.168.8.1.

Azndfc · May 4, 2020, 12:19pm

yessss…

once i changed the Lan to 192.168.8.2 and it didn’t work. Changed it to another two IP options (173.x.x.x and 10.x.x.x). I think only of them is going to be compatible with either of your devices (dongle and GLInet Router). Then I choose one of the two IP address prefix.

Voila, it worked!!
