My xbox series X disconnects and connects when connected to an ethernet port i havr tried...

Im having the exact same issue with my Series X as DMcC1 though im using the modem/router provided by Spectrum Cable in western NY. Ethernet cable works fine on xbox one and any other device I connect it to, but when I connect it to the series X it will
connect for about 2 seconds and then disconnect and tell me i dont have an ethernet cable plugged in. It then alternates between connecting for about 2 seconds and then disconnecting for a while and then repeats the process. Wireless connection seems fine.
I guess im glad to know im not the only one.

Hi all,

It’s not a new question I know, but is there any fix for the Ethernet port problem with the Series X planned?

I can see questions ranging back from release and it is making the unit completely frustrating to use. Any time it powers down, it disconnects from Ethernet upon restart and takes a long period of restarts, resets and unplugging to reconnect again.

It seems to be particularly bad when in energy saving mode, where it won’t connect at all. I’ve tried every way of resolving the problem but it simply reoccurs immediately afterwards and never stays connected for long.

Microsoft must be aware - are they planning a fix? Is it a hardware/firmware problem? Are all series x’s doing this?

I'm having the same problem. Unplugged my series x and played on another console, plugged my series x in and couldn't connect to internet using ethernet port. Wireless works fine. Did everything to diagnose the problem. Called Microsoft and I'm barely 2 months out of my warranty, go figure. Read up on this problem and we are definitely not the only ones dealing with wonky ethernet ports. Wish I had a answer for ya bud.

I have one Xbox (Series X) wired via Ethernet. I can play on WiFi with no disconnects but I prefer a wired connection for gaming.

I have the same problem and I've tried: reinstalling the game, rebooting my router and modem and Xbox, disconnecting my Xbox profile from battlenet and reconnecting it, giving my series X automatic Port distribution as well as doing it manually, I also removed a lot of devices connected to my router and checked the internet connection right after a disconnect but everything works fine
