A Problem With Your Router or Ethernet Switch

Perhaps the most likely cause of this problem comes down to your router or switch. If your router or switch is not working properly that can cause your Xbox Series X or Xbox Series S to not be able to connect via a LAN cable.

If non of your devices are working the problem is almost certainly with your router or switch. In this case you will likely need to replace the piece of equipment. You can try factory resetting it first, but that is unlikely to help given that this is most likely a hardware problem.

If your Xbox Series X | S is the only device having trouble connecting to your router or switch, try plugging into a different ethernet port. In some cases the port itself can stop working. This is especially common after a power surge or other electrical issue.

You can also troubleshoot by plugging another device into the same port your Xbox was plugged into. If that device works properly, the issue is likely not the port on your router or switch.

A Faulty Network Card on Your Xbox Series X or Xbox Series S

It is possible but fairly unlikely that the ethernet card on your Xbox Series X or Xbox Series S is not working. This is one of the less likely causes but certainly does happen. If this is your first time using the ethernet port on your Xbox, you are especially likely to discover this.

This is simply because it could have been faulty all along and you simply wouldn’t have known because you did not try to use it.

The easiest way to test this is to connect another device directly to the ethernet cable where your Xbox is located. If that device works, the issue is with your console. If the test device does not work, the issue is likely either with the cable or the router / switch that you are connecting to
