I have looked at a similar issue at: No network after latest update: Ubuntu 22.04
but I have a slightly different problem I think? I logged onto my Ubuntu 22.04 system today to find that I could not acces the internet? In settings, it shows my wired connection operating at 1000Mb/s? I deleted the profile, rebooted and then re-added the connection but no change? Software updater also says "Check your internet connection"? I have disabled the firewall too, but no change. I am a Linux novice but would appreciate any help please. I am using my Windows 10 machine at present.
