I have no connectivity with wifi or Ethernet

Question

I had a problem with Wifi connectivity that I thought was to do with the Realtek Network hardware on my HP laptop so I tried some of the fixes online and ended up with no connectivity at all.

I upgraded from Ubuntu 16.04 to 18.04 (using a usb connection to my phone) hoping that would resolve the problem but it hasn't My Ethernet controllers show as unclaimed

lshw -C Network

I tried a fix based on missing firmware from here Wifi not working on Thinkpad T460

But it threw errors

dpkg  -i linux-firmware*.deb
dpkg: warning: downgrading linux-firmware from 1.173.1 to 1.169.3

HP-ProBook-430-G2:~/Downloads$ sudo modprobe -r iwlwifi && sudo modprobe iwlwifi

Any ideas please?
