Xbox 360 Phat Freezing Help please

I have a Phat Xbox 360 , with a 250Gb hard drive . Wired Connection.

it freezes no matter what am watching or playing . but only when am conencted to xbox live.

things I have tried

removed hard drive . Cleared cache , deleted main profile , created a new sliver account all froze .

xbox is conencted right to the tv , xbox is sitting in a large open space .

if I remove my network connection I can play games with no issues.

I have xbox in DMZ , I just did port forwarding this morning and can test this tonight . but I've never had to do this in all my time on Xbox live.

any ideas ? or is this just done and I need a replacement ? I was thinking about opening it up and see if that will help ?

:)

 

My xbox keep freezing on start up and dashboard.

Someone please help my xbox 360 console keep freezing on start up screen and dashboard and I just got this console a month ago! Please help ):

 

Xbox 360 Issue HELP!

The other day, I was on my Xbox 360 and tried downloading the WWE Network app when my console froze. I restarted the system and logged back into my Xbox Live account and now every time I do log back in, my system freezes on the dashboard. It only does this when I log into my Xbox Live account. If I skip login, I do not have any issues.

Could someone help me please?!

 

Port forwarding resulted the same 5 mins in and frozen .

I am now testing no hard drive and connected to the Internet . Just doing the update .

 

Current status of me banging my head on my desk and coffee table .

Since port forwarding dm didn't help . I thought for sure it was my xbox . So I go out and buy another off kijiji .

Same as before a older phat xbox .

But had the wifi adaptor .

Connected to my 5ghz wifi and my 2.4ghz both worked great .

As soon as I plugged in my network cable (removed the wifi dongle)

And it froze with in 5 mins . So now this tells me my first xbox is fine as well .

I reset my telus router . And my dlink to default settings .

Still have the freezing issue .

I have by passed one switch and disconnected my pc from the network . Unplugged my wifi direct printer .

Testing now .

I hope someone can shed some light . If all else fails and I find my problem. This must help someone else

 

Samsung laser wifi printer with wifi direct seemed to be the issue . Now to find out why.
