Can't connect to internet no matter what on NVG510 ATT

I used to be able to get on Xbox Live fine, but now I can't for some unknown reason and I get completely different situations every time I try to connect. Sometimes when I try to test my connection it will stop in the middle, other times it will fail at
the third part, and other times it will tell me I need to update, and when I log in to my account it won't let me view my friends list. I am sick and tired of going through Xbox support because I have done it 5 times now and not once has it worked. Thanks

Connection to Xbox Live

No bridging available for this gateway... the best that can be done is the directions on this site

Can't connect no matter what

Actually did you look at the cmd command on your PC to copy the MAC address and enter it into the Alternate MAC option on the XBOX? That helped me connect - from not being able to connect at all - however now it keeps disconnecting randomly, but at least
I can reconnect from the dashboard. My router is also a DLink-655. And not only I have a wired desktop and a wireless laptop - but also a PS3 and Wii, bot connected wireless - and absolutely no problem, no disconnection at all from any of the devices?!?!

 

One thing I can suggest is to make sure that all your wires on your router and tightened and everything is plugged in securely. Please get back with me if this has not helped.
