Describe the bug
After booting the live version of Ubuntu 22.04 KDE, web browsing does not work.
Further investigation reveals that network drivers are working, and there is an IP address assigned by DHCP, however DNS is not setup correctly.
Disabling the network, and then re-enabling the network will reset DNS, and name resolution works.

This appears to be a problem on several versions of Ubuntu, and is a persistent problem on physical hardware.

Expected behavior
After booting to a live version of Linux, network should be operational, with DNS properly assigned.
