This is interesting. I updated my laptop and had a network issue as well, but mine was different - it wanted to use dnsmasq, which I don’t need (being an end-point, not a server), and dnsmasq wasn’t picking up the dns from dhcp.
Solution turned out to be to disable dnsmasq using systemctl and reboot.
I’m pretty sure it wasn’t installed by default in the previous version either, and maybe even the one before that. It’s a useful utility, after you locate it.
