Ubuntu 20.04 and Huawei Mobile Stick E3372

Question

I am trying to use the HUAWEI 4G Usb-Dongle E3372 with Ubuntu 20.04 but the module doesn't seem to work.

ubuntu@yolo:~$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 018: ID 12d1:14dc Huawei Technologies Co., Ltd. E33372 LTE/UMTS/GSM HiLink Modem/Networkcard

Do you have any advice?

It seems that your DHCP is working and also there are some sent and received packets . So what's the problem ? Have tried pining some IP like 8.8.8.8 ? — Parsa Mousavi, May 29 '20 at 14:57
Sorry, forgot to say that I am connected through an ethernet cable while trying to use the the stick. — UserK, May 29 '20 at 15:26
Have you tried unplugging the ethernet cable and then just plugging your stick ? — Parsa Mousavi, May 29 '20 at 15:31
You could check the below: https://askubuntu.com/questions/757638/can-not-connect-huawei-e3372-modem-on-ubuntu-15-10-please-help — George, May 29 '20 at 17:02
Thanks, I get `sudo usb_modeswitch -v 12d1 -p 1f01 -c /etc/usb_modeswitch.conf Look for target devices ... Found devices in target mode or class (1) Look for default devices ... No devices in default mode found. Nothing to do. Bye!` — UserK, May 29 '20 at 17:17
@George there was another answer which explained a logical process to make it work. Unfortunately, it was using setting network configurations using the interfaces file. Trying to get the same result using netplan. — UserK, Jun 01 '20 at 18:55

As soon as you plug the usb Dongle in and you get a steady blue led, issue:

ip link
5: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
    link/ether 00:aa:bb:cc:dd:00 brd ff:ff:ff:ff:ff:ff

you should get an eth1 as physical device.

If you are using network manager to handle connections, create an ethernet connection using eth1 and bring it up

sudo nmcli connection add type ethernet con-name huawei ifname eth1
sudo nmcli c up huawei
