Cannot connect a ethernet cable to my Xbox series X

Did you manage to fix the connectivity issue? My Series X constantly drops connection to xbox live/internet despite an ethernet cable being used.

Hi, I hope you're doing great despite the issue you're experiencing. I am an Independent advisor and I am here to help you in regard to your concern.

In order for us to isolate the issue if it's the console, the ethernet cable, your router/modem, or your network connection kindly try using a different ethernet cable, or try using the current wired cable on a different device such as another Xbox, PC, or Laptop to check if it will work.

Also, kindly perform an extended powercycle and reset your network hardware by following the steps below:

1. Unplug the power cable from the back of the router, modem, or gateway for 5 minutes. If you have a router and a modem, unplug the power cable from both devices.

2. Press and hold the Xbox button on your console for 10 seconds or until it turns off then wait for 2 minutes before turning it on again.

3. After 5 minutes, plug the modem or gateway in first, and wait for all the lights to return to their normal state.

4. If you are using a router, plug in the router and wait for all the lights to return to their normal state.

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

I have had similar problems with my sons series x dropping internet connection and the only way of curing this was connecting the console directly to the router with an Ethernet Cable. It now works with no issues. I hope this helps.

And to add my sons Xbox one worked perfectly on our WiFi with no issues but the series x has issues, I’ve no idea why it has these issues but the cable sorted it.

I don't understand on why my original xbox one was fine with 5GHZ but the series x just doesnt want to stay connected to it. And I'm unable to connect an ethernet cable as teh modem/router is no where near my xbox so I dont know how to improve the connection to my xbox
