My Xbox 360 has connection issues to Xbox Live

That's the issue - The gamertag I used on my XBOX 360 does not have an associated Microsoft Account or Email. It was an Offline XBOX 360 -- never connected it to XBOX Live. The gamertag has always been offline.

Hello GULLYDWARF,

I'm sure you can understand that when we hear "We've tried everything", its hard to know whether the correct troubleshooting step has been performed, or if the right article has been reviewed. Since we don't know exactly what's been done, we try to recommend
what we believe could resolve the issue.

So I went ahead and compiled a list of all troubleshooting I can see you have tried. based on what you have told us :

• power cycled console and network devices
  
• reset console to factory defaults
  
• Forwarded ports, and then undid them
  
• Bought a brand new Xbox 360, same issue
  
• Changed ethernet cable
  
• Reset network settings to factory defaults on 360
  

We'll do our best to recommend troubleshooting steps that you have not done.

So since the issue started when you got a new router, we can start by making sure everything is set up correctly. UPnP is a setting in your router that should be turned on for better performance. This setting is not turned on by default in some routers.
You can also start by lowering the firewall settings.

Note that after changing any settings in the router, you will have to unplug your router for about 30 seconds for the settings to apply. For assistance with your in router settings, refer to your owners manual or
Linksys support.

Hi Gully,

Thanks for coming to the forums with your issue and creating a new thread. Sounds like the issue is the NAT type for the 360. Unfortunately, you are unable to view it like on the Xbox one. Have you tried

restoring to factory default the network settings? If not, try this and let us know.

Thanks,

Brad

Hey Gullydwarf,

I would recommend trying to turn off the firewall completely, only to test out the console immediately after. If you notice that the issue is gone, then we can turn it back on, but at a lower setting. From my routers settings I get the basic High, Medium,
Low settings for my firewall. I'm hoping yours has something similar?

Another thing to test would be the DNS settings. Updating the DNS configuration in an Xbox helps solve issues involved with video streaming, along with using the internet browser. Try this out :

1. Press the Guide button on your controller, select Settings, and select
   System Settings.
2. Select Network Settings.
3. Select Wired Network or the name of your wireless network when the network list is displayed.
4. Select Configure Network.
5. Go to your DNS settings and enter these manual DNS numbers

Primary DNS - 8.8.8.8

Secondary DNS - 8.8.4.4

Save the settings, then restart the console.

I have some more things to try, but I'm curious to know the results of these tests. Let us know the results!
