What’s going on with my Xbox

I am guessing that you are connecting through wifi? Try connecting via a wired network connection. I was having the same issues until I did this. If you need any more support go to: https://support.xbox.com/en-GB/xbox-one/networking/network-settings#f0f6be5eb9f34d82a2888fbae0f2dde9

I had the same problem. I have a BT home hub. This is a security setting on your modem/router. You have to tell the router to always assign the same IP, you're router will have a settings page on aan IP address of something like (192.168.0.1). This is how
I solved it with my home hub (taken from the BT forum):

To solve the 'Strict NAT' problem if you have a Hub 3:

Hold down the Reset button on the back of your BT Home Hub 3 for 20 seconds to clear any old port mappings. You'll need to use something like a paperclip or pin to do this.

Turn on your games console.

Open your web browser on your computer and type in to
http://bthomehub.home to open the Hub Manager.

Click the Settings tab. You'll be asked to enter a password.

Click on Advanced Settings, then Home Network.

Your games console will be listed on the devices table. It may be identified by its MAC address, for example "Unknown-00-0d-3a-be-48-c8". You can find your games console's MAC address on a label, or by looking at the console's management pages.

Click on your games console in the connections list to open a detailed information page.

At the bottom of this page there's an option to Always use this IP address. Click Yes followed by Apply.

With the Xbox One games with gold games, you have to have a gold subscription in order to continue playing them for free.

xboxlive is having a service alert or something , it doesnt let the gold members sign in because all of my gold accounts cant sign in & my silver's can , im tired of this & im really thinking about Ps3 , xbox step your game up.

Hello TH3, sorry to hear you were having trouble.

Glad your money was refunded and hope that you're able to find a console to your liking in the near future.
