  • You have an ethernet cable plugged in, and Ubuntu has decided that it's a better connection than your wireless connection. If you want to stick with wireless, just unplug the cable. – heynnema Jun 17 at 19:43

  1. This icon means that your route settings preffer the ethernet connection on other connections.
    • If there is not a ethernet cable connected to your computer and you computer still trying to use that connection check those options:
    • static ethernet connection is set up, check it by clicking on ethernet icon->"edit connections"->if there is ethernet static connection delete him.
    • now reboot your computer and check if wifi is working.
    • if it is not working try step 2.
  2. Execute the command ifconfig and look for your eth connection, it should be named as eth0 or enp0s3.
  3. Now execute the command route -n.
    • now look for your ethernet connection name under Use Iface.
    • check for your ethernet connection metric numeric value.
    • The interface with lower metric is preferred for Internet.
  4. If the ethernet connection have the lowest metric value you can change it with ifmetric command.
    • install the ifmetric with sudo apt update and sudo apt install ifmetric.
    • execute the command ifmetric ethInterfaceName numericValue
    • for example ifmetric eth0 1000
    • or just give a better priority to your wifi interface
    • for example ifmetric wlan0 0.
  5. If that is working you can reboot the computer to check that is stable.
    • if it is not stable you can use crontab -e to run this command as a scheduled task.

if this solution not working please specify your problem by posting the commands output as and edit to your question so i could help you solve the problem.
