Xbox one Ethernet port not working

Have you tried physically power cycling your console? It will help your Xbox do a quick 'reset' and may resolve your problem. Here is more information at Xbox support on how to do this:

Good luck!

Hey there LadySaiph!

I'm sorry to hear about the console issues. If you haven't yet, the next step I'd recommend is performing a full

factory reset of your console. If that doesn't do the trick and you continue to experiencing disconnections, you may want to consider having the console repaired. That process can be explored via our
Online Service Center.

Hopefully the factory reset does the trick though. I'll keep my fingers crossed.

I am having the same problem with my xbox too. One day i turned it on and the sign in deal keep saying I was off line. I tried different cables and that did not work. I know the line is good because I can plug my laptop in and get the interent. My xbox is
about 2.5 years old. Any ideas? I really want to use my cable because I took the time one weekend and ran the cables to my location where the xbox was.
