Xbox Can't Connect through an Ethernet Port

Lamjh23 on 13/03/2022 - 16:26

Hi all, I moved my Xbox One X into the home office yesterday and now I can no longer connect it to the internet.

The office has a newly installed ethernet wall port which works when I plug my laptop into it. The set up of this is an Ethernet cable running under the house with an Ethernet wall socket connected in the lounge room next to the modem and another wall socket in the office. An Ethernet cable runs from my Telstra Smart Gen 2 modem to the wall. My understanding is this should act simply as an extension but is the Xbox somehow getting confused when trying to connect?

When I plug my Xbox into it and navigate to advanced network settings it simply keeps flickering between 'connected' and 'not connected' every 10 seconds or so. I have tried
- different different cables
- power cycling the Xbox and modem
- reset of the Xbox (kept games & files option)
- reset of the modem through pressing the reset button with a pin as well as factory reset when I login to the modem dashboard
- clearing the Mac address on the Xbox
- applying a port forwarding option to the Xbox when I log into the modem dashboard

Does anyone have any ideas of how I can fix this?

    I'd recommend moving the Xbox next to the router and plug it directly in. If it works, the issue is somewhere along the new cable route - potentially the cable is damaged, or is crossing over some of the wires inside.

    You can use an ethernet cable tester to check the wires are paired up properly - the main kit sends a pulse down each of the 8 wires, which should pulse on both ends with the same number if they're paired up in a straight-through configuration

    Something like this (though you can find them cheaper on eBay): https://www.amazon.com.au/MonopriceRJ-11-RJ-45-Modular-Teste…

      Most likely a cable fault.
      Try plugging in a laptop or desktop computer to the home Office Ethernet socket and see if it connects successfully.

      If that doesn't work try plugging direct into the modem with the same Ethernet patch cable.
      If that works fine, then it's a problem with the Ethernet wiring under the house.

      If it doesn't, then your Ethernet patch cable is the problem or the modem has some funky settings per other suggestions below.

        Thanks for you reply Elegant Giant & ESEMCE.

        I have tested my laptop in the home ethernet port and it works fine. I'm now leaning toward it being the cabling under the house, even though I'm sure I saw the person who installed it test things with a modular tester.

        After going through everything I have tried to fix the issue, he is coming back out to run a new cable under the house in the next week or two.

        I will keep you updated with the outcome.

          If Laptop works fine, then I suspect it's the compatibility issue mentioned in the bottom post where a network switch resolves the issue.

    MAC address firewall setting is my guess without digging further down the details

    clearing the Mac address on the Xbox

    That won't help. You need to whitelist the Xbox Mac address on router if there is such a thing

    • bmerigan on 13/03/2022 - 21:25

      That wouldn't be a default setting though, otherwise no new device would work.

    • amjh23 on 14/03/2022 - 12:21

      I'll have another look on the dashboard to see if that is a thing. Thanks

  • leighjames on 13/03/2022 - 19:02

    Check that your XBOX has the ethernet enabled.

    Check your DHCP server is handing out IP addresses.

    • amjh23 on 14/03/2022 - 12:29

      I'll double check this but I'm pretty sure it is enabled as when I plug it directly into the modem I don't seem to have any issues connecting it to the internet. Thanks for the suggestions

    It may be that your patch cable is a crossover cable, rather than straight through. Your laptop may auto negotiate cable type where as the Xbox won’t.

    As previously suggested plug the Xbox direct to the modem and see if it works, or try a different ethernet cable from the modem to the wall.

    • amjh23 on 14/03/2022 - 12:22

      We are going to try to run another cable under the house. The installer said that the first one is a cheap cat5 which may be causing the issue. He is coming out in the next week or two to run another cable to see if that fixes the problem. Thanks

  • Leo Getz on 13/03/2022 - 21:24

    What is the distance between the router and your home office?

    Has the laptop been joined to your wireless network previously?
    Maybe that made it appear to work when plugged in to the new data outlet.

    Has the Xbox been connected to your wireless network?
    Is that an option?

    Whoever installed the ethernet cable needs to come back and check they punched down the wires correctly.

    All the other troubleshooting suggestions are good but the recent change is at the physical layer (OSI Model) ie. Ethernet cable under the house.

    • amjh23 on 14/03/2022 - 12:27

      I would estimate between 10-15m, which I am assuming shouldn't be an issue?

      I disconnected the wifi on the laptop and then plugged it in to the ethernet port just to make sure it wasn't the wifi providing internet access.

      I have been able to connect it to the wifi which will act as a temporary solution but will get the installer back to run a new cable to see if that fixes the issue.

      Thank you very much for your suggestions

    Had the same problem with my Xbox and the Telstra modem. Somehow, the Xbox can't talk to the modem directly. Just put a small switch in between and everything now magically works.

    • amjh23 on 14/03/2022 - 12:27

      Sorry for the silly question but what is a switch?

      • AlphaQ on 14/03/2022 - 13:52

        Network switch. Get a 5 port unmanaged plug and play one about $20 will be enough. Or search FB marketplace for a free used one.

        • amjh23 on 14/03/2022 - 14:05

          Thanks, I'll look into that

        • ESEMCE on 15/03/2022 - 15:50

          or an old modem connecting the LAN ports only.

          • amjh23 on 16/03/2022 - 12:49

            @ESEMCE: I have organised to borrow my brother in laws switch this week, fingers crossed it solves my issue too

  • amjh23 on 18/03/2022 - 21:31

    Thank you again everyone for the suggestions. I tested out a network switch and that has fixed the problem. I'm not sure how but I'm just happy that it works

    • ESEMCE on 21/03/2022 - 08:44

      That's just weird!

      • amjh23 on 21/03/2022 - 12:33

        I agree. I'm glad that it has fixed the issue but I hate not understanding the 'how'

        • ESEMCE on 21/03/2022 - 13:35

          I just read that disabling IPv6 in your modem can resolve a similar issue.

          • amjh23 on 24/03/2022 - 14:51

            @ESEMCE: I might give that a go as well at some stage
