To open your router's user interface, open a web browser on your computer and enter your router's local IP address in the address bar. Then you will need to enter the administrator's username and password to log in. You can find all this information in your router's user manual or on the manufacturer's web page.

- Common administrator usernames and passwords include: "admin," "12345", or simply left blank.
- Your router may have a sticker on the back or bottom that instructions on how to log in to the user interface. This should contain the local IP address as well as the default username and password.
The user interface for each router model is different. Locate the option to update your router and click it. Follow the instructions and allow your router to check for updates and install any new available firmware updates. Once it is done, restart your router, log in to your Xbox One, and check your connection status.
If your router's firmware is up-to-date, and you are still experiencing NAT errors on your Xbox One, log in to your router's user interface and check to see if it has a Universal Plug and Play (UPnP) mode. Enable this setting if it is available on your router's user interface. Save your router settings and restart your router. Then check your connection status on your Xbox One.
If you are still having NAT connection problems with your Xbox One, log in to your router's user interface and check for the option to enable Teredo Tunneling, and/or IPv6 Tunneling. Enable this option and save your router's settings. Restart your router and check your connection status on your Xbox One.
