NAT type changes to ‘Strict’ every week. Used to be ‘Open’ and somehow becomes stuck at...

Hi 4bel,

First off here is a link for you to be able to check the status of Xbox Live services if you are having issues, which may be due to an issue occurring on Xbox's services.

1. If able to hardwire into your modem do so as it is your optimal connection type. Even if only for testing purposes this will help determine if the issue is with wifi or potentially entire network connectivity/ISP.. if already wired then, Change your
network LAN cable to a high speed Cat 7 cable or Cat 8 as they are rated to support ultra high speeds where Standard cat5 or cat 6 cables do not typically handle higher than 1GB and actual speeds can be affected based off of length of cable and quality of
cable as well as if the RJ45 connector tip is loose or not punched down on the wires correctly.

2. If on Wi-Fi ensure that your network security settings are using at least WPA-2 and not an open network, and that your network SSID name being broadcast is unique and broadcasting in both 2.4ghz and 5Ghz bands. Also ensure that you have UPNP enabled
on your modem and that you have set up port forwarding to the recommend ports listed by Xbox to ensure open NAT which is needed for best quality online live service and multi-player gaming. Here is the link about what ports should be forwarded-

3. Set a reserved static IP for your Xbox on your modem and also set the static information in your Xbox network settings. Also try changing your DNS settings on your Xbox to manual and set an open DNS IP address like Google or other provider. Google DNS
is 8.8.8.8 and 8.8.4.4.

4. Check your modem configuration to ensure that DHCP is enabled for ipv6 if not using a static address, as well as make sure that your lease times are set to no more than a day or two. This will help release the lease faster clearing the table if you
have many devices connected and force a reassignment of IPs to only active devices.

5. Perform a system reset without removal of apps or games to ensure caches are cleared and the system is running fresh with no stored configs.

6. Another great test if hardwired is connect another device to the same cable and see if it too has issues, that will inform you if line or modem/config related or hardware issue.

7. Last thing I would recommend is speaking to Xbox tech support to further troubleshoot to help determine if a hardware failure and if service is needed as sometimes wifi cards and lan port do fail or a pin can get bumped out of place when connecting
or disconnecting cables.

Good luck and hope something here helps!

hmm did you open your nat type because when you change router and stuff your nat become strict. making xbox live harder to connect

I'm stuck on a strict nat type can anyone help me to change it?

No, just the one Xbox One. I've somehow managed to get my NAT open as I've said for about a week now and just yesterday, for reasons that elude me, I signed in to find a Strict NAT type in my network settings. I'm really at a loss now.

is your router set to open or closed? Having the router open makes the strict nat change to good nat type.
