    Xbox Series X thinks a Ethernet cable is plugged in, when one isn’t.


    My Xbox Series X keeps thinking its wired via ethernet cable when its not, so wont let me connect with WiFi. A power cycle restart fixes it, but when i turn it off and back on later to play it thinks its wired again. Ive tried plugging in a ethernet cable
    and the unplugging it, didnt change anything. Ive factory reset the console several times and hasnt helped. On the inital setup of the console out of the box it also thought it was “wired”.

    I have the same problem. If my internet cable is plugged in I can't login to Microsoft. Going wireless does work. My XBOX also said my cabe was plugged in when it was not. To fix I turn off the console and unplug from the wall for about a minute. When
    turned back on it fixed the problem.

    Good Luck!

    Xbox Series X Unstable Wired Network Connection, Ethernet.

    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.

    XBOX Series X - WiFi issue

    I have the EXACT same issue.

    Comcast Xfinity Cable/Modem

    I have tried both 2.4 GHz and 5Ghz

    NAT is open

    Change the channel on both frequencies to a less crowded one

    Port forwarded all xbox live ports

    Unplugged and Rebooted BOTH series x and router

    Setup static IP

    Factory reset series x twice

    In advanced network settings and statistics (when on WiFi) on Series X

    I have 100% signal strength

    Latency is 197ms

    0.01 Mbps download

    0.14 Mbps upload

    51% packet loss

    Series X is 10 feet from the router in the same room

    Nothing works. The instant I plug in an ethernet cable everything is fine, except now I have an ethernet cable cutting the room in half across the floor.

    All other devices (consoles, laptops, iPhones, iPads, smart TVs) are working perfectly on WiFi.

    If someone else has something else to try I would love to hear it
