D-Link: xbox live

That particular D-Link router is not listed
support.xbox.com/.../network-hardware-compatible-xbox-live as being compatible with multiple Xbox consoles. That doesn't mean it won't work, but it's unknown whether it will support multiple consoles well. UPnP is essential to multiple consoles; make sure
it's turned on in the router setup,
http://www.pcwintech.com/screenshots-d-link-dsl-2640r-d-link-firmware and that Port Forwarding and DMZ are _not_ turned on. It doesn't look like Port Triggering is available in that router; if a firmware upgrade from D-LINK makes it available, I would strongly
suggest it.

Hi Again

My Modem Is Symphony And My Friend Modem Is D-Link

I Tested my Xbox 360 with Symphony But I Cant Connect to Live ( I Think Becuase Symphony Modem Is not Supported By Live )

Then i Tested My Xbox 360 with D-Link And I Connected to Live (I Think Becuase D-Link Modem Is Supported By Live )

When I Test My Xbox 360 With Symphony I Recive MTU Error

But When i Test My Xbox 360 With D-Link I Connect To Live

My Question Is How Can I Add My Modem to Supported Modems In Live in :

forums.xbox.com/.../default.aspx

Try a hard reset of the xbox hold the home button for 8 seconds till it completely shuts off and unplug the xbox for 5 minutes then forget your network and try reconnecting

Make sure Xbox Live is fully supported in your country: http://www.xbox.com/live/countries

Microsoft is aware of this problem with this sign-in error in most middle-Eastern countries and are working to fix it.

If your country isn't listed here, then I am afraid there is no workaround for this.

Let's just hope this will be resolved so that unsupported countries can access the Xbox services.
