Ubuntu 18.04.1 - TP-LINK UE330 Ver: 2.0 driver problem

I just buy a new USB 3.0 Gigabit Ethernet Adapter and I can't install it in Ubuntu 18.04.1 server x64 edition.

I contact tp-link support and they send me the driver. I install the driver but my adapter is still without Internet connection. I follow this steps too and without any success.

Anyone can help me to fix this issue?

EDIT:

The name of the file that is in the /etc/netplan/01-netcfg.yaml

CONTENT of /etc/netplan/01-netcfg.yaml

  # This file describes the network interfaces available on your system
    # For more information, see netplan(5).
    network:

Thank you in advance.


Solution 1:

Try this...

In terminal...

cd /etc/netplan # change directory

sudo cp 01-netcfg.yaml 01-netcfg.HOLD # backup the file

sudo pico 01-netcfg.yaml # edit the file

replace what you see there with this...

# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
  version: 2
  renderer: networkd
  ethernets:
    enp19s0:
      dhcp4: yes
      optional: true
    enx503eaa8b183c:
      dhcp4: yes
      optional: true

then...

sudo netplan generate # generate the config files

sudo netplan apply # apply the new configuration

reboot # reboot the system

review the previous lshw and ifconfig commands to check operation.
