I have a 4 year old Xbox that I don't have any problems with. I can connect to Xbox Live, and play online, etc.
I borrowed my nephew's newer black Xbox, and I can't get it to connect. I keep getting the "Can't obtain IP address" error.
After trying his Xbox, I switched back to mine, and mine connected fine. I've tried all the solutions on the IP address error Support page.
I plug the Xbox directly into the modem.
Are there any other solutions I can try?
What Country/State/Province do you live in?
Modem brand & model number: Not sure, I'm at work right now and can't check.
Router brand & model number: Not using one.
If Wireless, are you using a white or black external adapter, or an internal (Xbox 360S) adapter? N/A
Things you have tried:
Is UPnP Enabled? Yes/no/Unknown Not sure
Do you have a NAT error? If so, what is your NAT?
After you run "Test Xbox LIVE connection" press “Y” for "More Info”. In the pop-up that appears, what are the following values, if shown? (If a value below does not appear for you, just leave it blank.)
Sorry for the lack of additional info here. I'll edit this post with the specific error codes when I get home. Any suggestions or ideas would be welcome!
