I have a Huawei E3372 USB dongle for connecting to LTE 4G mobile networks.
With this I use a SIM from a Swedish provider.
When I plug this into a Raspberry Pi4 device it connects in about 20-30 seconds and I can use it to communicate on the Internet.
The command ifconfig shows both eth0 and eth1 in the list on RPi4.
Now I would like to use it on my Ubuntu Server 20.04.3 (no desktop available) so I plugged it into USB2 on that computer.
And after the usual time the dongle blue light came on indicating it has connected.
But the connection does not appear inside Ubuntu!
So I would like to know if there is someone here who has succeeded in making it operate on an Ubuntu Server?
Information:
On the RPi4 the plugging in of the dongle causes a new network adapter to appear as eth1 and it is given a private IP address as shown:
But on the Ubuntu server the ifconfig command does only show eth0, which is my wired connection.
I have checked more on Ubuntu with the dongle connected:
As you can see the dongle seems to exist but is not in a usable state...
I have tried in vain to find a solution by googling, mostly I get to Windows related posts or to very old Ubuntu discussions...
How can I enable the eth1 interface on this Ubuntu Server 20.04.3?
