Unlock Huawei E3372

[Kenneth]

Havingsaid that I have found that the Huawei is a good modem with a very good receiver front end. I find that I can hang onto a weak 4G signal with the E3372 which is not the case with a TP-Link MR200 that drops the signal at any excuse! (Both connected to the high gain antenna)

hello all, the same problem, I bought a usb lte huawei E3372 key but my mt300a does not recognize it, the latest firmware installed on the 2.261.

Who would be the person who tested this E3372?

Is it useless to try out the latest firmware versions?

What alternative can you point to instead of the E3372

I'm using an USB Stick Huawei E3372 via kmod-usb-net-cdc-ether. It's like a usual Ethernet device with a Gateway on 192.168.8.1 and a webinterface for configuration. Too bad, the network is fixed to that 192.168.8.0/24 address in the firmware and can't be changed according to many threads in the internet.

This conflicts with my main VPN.

Hi.

You can modify this HiLink it to a S ( stick ) mode serial.

On S mode you will get rid of double nat. It will be a NCM usb lte dongle ( no more ether-cdc no more 192.168.8.1. Your new interface will be dhcp mode from you ISP)

Ok, reading -a-huawei-e3372h-4g-lte-stick-from-hilink-to-stick-mode/ I got an idea what you mean. So the firmware of that device needs to be flashed to that other version.

Afterwards, will I still be able to access the webinterface of the device? I guess not, but this is very useful to evaluate the reception quality, setting the mobile network modes etc. And actually using the ether-cdc mode is also quite comfortable.

So there is no other way to just mask or alias the 192.168.8.0/24 network to something else? Linux should have ways for something like that.

For the mobile network mode, it seems you are already doing things in your config like "preferlte", is that documented somewhere? Is it possible to create that config via LuCI or only via editor? Which OpenWRT packages would I need for NCM?

I think you might need to place wan and your VPN interface in a new namespace then veth pair with one end in new namespace and other end in normal namespace. The link above provides everything you need on how to do that once you have ensured you have the 'ip-full' package installed or otherwise have namespace support.

I tried myself to do this but failed to make it all work so I'd really like to know how you manage it if you do. In particular, I managed to set up the namespace and veth pair particulars, but I could not work out how to set up the routing on both sides, and then gave up. My use case is different to yours, namely I just want a single interface on which to apply CAKE to both VPN and non-VPN traffic. I ended up using the 'ifb' approach, but would still be interested to try this namespace/veth approach if I can see how to make it all work.

HI.

Correct, no more web-interface for the E3372. You will only use luci network --> interface to configure your LTE connection.

You can use 3ginfo to monitor your connection status.

-app-3ginfo

No alias, as serial mode the usb modem will deliver a dynamic IP provide from your ISP to your LTE ( wwanX ) interface.

Hi.

Same for my huawei B315s in bridge mode with a public IP provided to my openwrt router I still connect to the web interface of the B315s.

And as your huawei is a modem router too, but this E3372 is a modem only, and with S mode no more gui interface needed.

You can add an infinite number of such exceptions. All it hurts is the ability to use those addresses on the WAN, which usually isn't a problem for 192.168.0.0/16 and the likes. Although it could be since mobile operators like to use CGNAT with RFC1918 addresses.

I try to connect to Internet with an LTE Stick from Huawei (e3372). I installed usb-modeswitch, ppp and wvdial. modewswitch is working correctly. The device is mounted on /dev/ttyUSB0 where i am able to send AT commands. I want to connect with wvdial but it always say "The PPP daemon has died: A modem hung up the phone (exit code = 16)" The console print of my wvdial command is :

It's a bit old topic, but I would like to contribute as I found myself in trouble with this particular modem and the problem I had and I can see in this post too is using ttyUSB0, if someone ever has that problem again: try changing to ttyUSB1. Modem communicates as two devices, both accept commands, but ttyUSB0 not only hangs up, but also freezes modem!
