Not connecting online

So my console is connected to the wifi, but my multiplayer test isnt working still. Im on the wifi but I cant talk to or play online games.

Try to sign out and sign in again if that doesn't helps...

To solve the issue you are experiencing I suggest you to remove the account from your console, clear the console cache and download your account again. Follow the step by step instructions:

a)To remove the account from xbox live console:

Scroll left on the Home screen to open the guide.

Select Settings.

Select All Settings.

Under "Account," select Remove accounts.

Select the account that you want to remove.

Select Remove to confirm.

When you're finished, select Close.

b) To clear cache on an Xbox One:

Press and hold the power button on the front of the console until it powers down completely.

Unplug the power cable from the back of the console so that the power brick in not connected to the console.

Press the power button on the console three or four times. This will ensure that any remaining power in the battery is drained, clearing the cache on the console.

Plug the power cable back into the console.

Wait for the light on the power brick to change from white to orange.

Turn on the console using the power button.

c)To download your Xbox profile to the Xbox One console:

1. Scroll left on the Home screen to open the guide.

2. Scroll down, and then select Add & manage.

3. Select Add new.

4. Enter the email address for the Microsoft account that's associated with your Xbox profile, and then select Enter.

5. Enter the password for your Microsoft account, and then select Enter.

6. Read the Microsoft Service Agreement and Privacy Statement, and then select I Accept.

7. Follow the steps to configure your Sign-In & Security preferences and download your Xbox profile to your Xbox One console.

Hope this helps you!

Hey there!

Thanks for the detailed information! Unfortunately the Technicolor Gateway you mentioned has a little bit of a history with random disconnects from gaming services such as Xbox Live, and there isn't a lot of troubleshooting we can offer due this. We do recommend
reaching out to Comcast to see if they can offer any troubleshooting steps or an alternative device that doesn't have any issues with disconnects. We also recommend possibly looking into acquiring a standalone router and a standalone modem that is recommended
for use with gaming.

We have had some users have success 'bridging' a standalone router to that Technicolor gateway (which basically turns off the router functionality of the Technicolor and works strictly as a modem), but you may need to reach out to Comcast for assistance
with setting that up. We also recommend having a look at our Technicolor
Known Issues post for more information

Please let us know if you have any addition questions!

That's where i got the third party headset fix from, but thanks anyways.
