Ethernet cord won't work on Xbox one. (Works with everything else)

Can you please provide the below information.

What Country/State/Province do you live in?

Modem brand & model number:

Router brand & model number:

How many Xbox 360 and Xbox One consoles are connected to this router?:

Wired or Wireless (for each console):

Things you have tried:

Is UPnP Enabled? Yes/No/Unknown:

Do you have a NAT error? If so, what is your NAT type?:

Any Error Codes you encounter:

Who is your ISP? (Internet Service Provider):

If you are connecting straight to your ISP Modem, please understand that you need to restart everytime before doing so. When you start your modem it does a Address Resolution Protocol and make a table to the hardware address of the equipment connected.
(aka an ARP TABLE). ARP tables don't update very well because they cache entries to make up for better connection speeds (otherwise you'd have to ARP request all the time). Restarting the modem, resets the ARP table. The easiest solution to resolve this
is to buy a 4 port switch (not a hub) such as the one found here (www.amazon.com/.../ref=sr_1_4).
Switches are designed to refresh their ARP table at a much faster rate than the modem itself. Please try connecting the XBONE using the CAT5e cable and restarting your ISP Modem and report back.

I should also state that I'm using a cat 5e Ethernet cable.

You may want to check the ethernet cord by plugging it into something else. If it works fine with the cord, its an issue with your ethernet port on your xbox.

If it doesn't work, try a different cable and/or port on your router.

Hi Harry, my name is Rodrigo. I'm an Independent Advisor and a member of the Microsoft community and I'd love to assist you today.

I am sorry to hear that.

Have you tested another LAN Cable? It's also a good idea to change the LAN Port on your router.

Please, try clearing your MAC address.

Press the Xbox button to open the guide.

Select Profile & system, then Settings.

In the General tab, select Network settings > Advanced settings > Alternate MAC address > Clear.

Restart your console. Press and hold the Xbox button in the center of your controller to open the Power Center.

Select Restart console and then select Restart.

(If the console appears to be frozen, press and hold the Xbox button on the console for 10 seconds, until the console turns off. After the console shuts down, touch the Xbox button on the console again to restart.)

Sign in to your console.
