Networking – How to reset Host Only Adapter Networking for Oracle VirtualBox VM Manager

localhostnetworkingtcpipvirtualbox

My Host Only Networking stopped working, how do I reset it ?

I tried disabling and re-enabling Local Area Connection and VirtualBox Host-Only Network but VirtualBox Host-Only Network is still showing on Unidentified Network / not getting internet, making all my VM's on 10.0.3.15 and not able to communicate with one another.

Any suggestions?

Blindly using vboxnet0 as your interface name will not work for everyone, or even most people.

  1. Use ifconfig to get a list of your network adapters.

  2. On my machine it was the ethernet I wanted to restart, but yours may be wlan. The ethernet interface on my machine was enp0s3.

  3. Use the ifconfig commands @encgoo mentioned. sudo ifconfig enp0s3 down && sudo ifconfig enp0s3 up. Replace enp0s3 with your own interface name of course.
