New 20.04 install, wired ethernet disconnected
Hello all,
I re recently set up 20.04 on a dell machine and everything was working ok but the hardware was getting a bit long in the tooth. The dell had a realtek ethernet chip. I built a new box with an Asus rog strix b550f motherboard. The Asus has embedded intel ethernet and wifi.
I moved the boot drive from the dell to the Asus and it booted with only one problem. The ethernet shows as disconnected. Ip a lists the interface as down. I have tried all the suggestions for tweaking the network manager and also tried disabling it. I have used the nm gui to manually add the interface.
None of these has altered the disconnected status of the ethernet interface.
I then reinstalled ubuntu thinking that it might auto-detect something that would allow the interface to come up.
Zero luck.
I have read about a hundred threads that were responding to questions about wired ethernet being disconnected. They all basically repeats the same “solutions”. Occasionally people say their problem, whatever it might have really been, was solved but many more report no success.
Does anyone out there know enough about this to give me a specific answer as to why the status is “disconnected” and nothing I do changes that? Is that embedded Intel chip incompatible in some way with ubuntu? btw, the embedded Intel wifi chip worked fine after the reinstall whereas it has nor worked after switching machines.
The only info that the system offers is the output of ip a, which shows enp6s0 as down and the dropdown of the network icon in the task bar shat sats ethernet disconnected. No other obvious error messages.
i hope there is someone out there who can answer these questions with some new information.
Thank you in advance
