I followed some suggestions: https://askubuntu.com/questions/906636/ethernet-adapter-was-disable-on-ubuntu-17-04/909185#909185 to fix the problem. Specifically, I edited the file: /usr/lib/NetworkManager/conf.d/10-globally-managed-devices.conf and changed the line unmanaged-devices=*,except:type:wifi,except:type:gsm,except:type:cdma to unmanaged-devices=*,except:type:ethernet,except:type:wifi,except:type:gsm,except:type:cdma
I also followed the suggestion: https://askubuntu.com/questions/1039233/no-wired-connection-wired-unmanaged-ubuntu-18-04/1043244#1043244 and edited the file: /etc/NetworkManager/NetworkManager.conf and changed the line managed=false to managed=true After sudo systemctl restart NetworkManager and a reboot the problem seems to be fixed. Incidentally, there were quite a few problems with the upgrade, and I had to reinstall the Ubuntu Desktop to fix some of these. I do not know if the NetworkManager files were changed or deleted when I did this. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1986444 Title: network-manager fails to detect usb internet adapter Status in network-manager package in Ubuntu: New Bug description: Since I upgraded to Ubuntu 22.04 from 20.04 several days ago, my ugreen network adapter is not detected even though the lights between the ethernet cable and the adapter are on. I am using a Dell G3 3500 that came with windows 10. The adapter works ok on my Dell XPS and worked fine with Ubuntu 20.04 on the Dell G3. Other devices are detected when plugged into the usb. The wifi is working. Any help with this would be appreciated.
