Series x disconnecting from live/internet

Hello there @BAM4_, I hope everything is going well!

Thank you for reaching Microsoft Xbox Forum support. I am sorry to know about the connection situation, but I want you not to worry about it because I am here to help you out! I believe your console might need either a network reset or just a system refresh.
I would like you to go through the following steps to clear the Mac address and then perform a quick power cycle on your console:

Settings > Network Settings > Advanced Settings > Alternate Mac Address > Clear it and the console should restart. It would definitely help if you could restart the internet router while the console is restarting.

After going through the troubleshooting steps mentioned, I invite you to perform a quick power cycle by turning off the console and then unplugging all the cables. After 2 to 3 minutes, re-plug them back again, then restart your console to check if it's
installing this time.

Another thing you should check is your NAT type. I would like you to check your NAT type if open because that could sometimes interfere. to check for the NAT type you can follow the steps below:

Settings > Network Settings > NAT type => It should be open.

If the NAT type is not open, you will need to open some ports with your internet provider. These ports must be open for Xbox Live to work: Port 88 (UDP) Port 3074 (UDP and TCP) Port 53 (UDP and TCP) Port 80 (TCP) Port 500 (UDP) Port 3544 (UDP) Port 4500
(UDP).

In case the issue still persists after the previous steps have been performed here is the official link to all the network troubleshooting steps that can help sort this out for you.

In case the issue still persists, the next step would be to perform a reset on the console. To do so you will need to follow the steps below to perform a reset on the Xbox :

Settings > System > Console Info > Reset This Xbox > Reset and Keep my Games and Apps.

Note =>The "Reset and Keep my Games and Apps" option will not cause losing your games, but please be aware that you need to be completely aware of the email address as well as the password of your account before going for it because it will require you
to sign in to the account.

I wish you a lovely day, and I hope this helps you out! All the best!

Kind Regards

Stay safe, and happy gaming!

Hi, I hope you're doing great despite the issue you're experiencing. I am an Independent advisor and I am here to help you in regard to your concern.

Let's perform an extended powercycle and reset your network hardware by following the steps below:

1. Unplug the power cable from the back of the router, modem, or gateway for 5 minutes. If you have a router and a modem, unplug the power cable from both devices.

2. Press and hold the Xbox button on your console for 10 seconds or until it turns off then wait for 2 minutes before turning it on again.

3. After 5 minutes, plug the modem or gateway in first, and wait for all the lights to return to their normal state.

4. If you are using a router, plug in the router and wait for all the lights to return to their normal state.

Also, if that didn't work and just for us to be sure if it's the console indeed there are some things that we can also try.

1. Try a different ethernet cable.

2. Try a different network connection.

If the same issue occurs after all this it may mean that it is indeed the console.

I sympathise. Since this latest update my xbox one keeps disconnecting from the internet saying no network detected when the settings says it is. I have a series x haven't tried that yet to see if same issue .

Check the forum or just google "XBOX Series X disconnects from wifi". Tons of threads here and on reddit since the launch.

An example.

Hi Katie, I'm Ryan.

What ISP are you with, and what's the specific brand and model of your router/modem? Does the same issue occur on both WiFi and a wired connection with an Ethernet cable?

What OS version are you currently on? Settings > System > Console info.

If the issue perists, please report it via the Report a Problem app so that it can be looked into:
