I can't sign into live - it was working fine 15 hours ago, but now I get the message with error code 80151901.
I'm using the internal wireless from my new 360. I test my wireless connection and it finds the router fine - plenty of signal bars - but it fails at the first stage every time. I've tried the whole "unplug router and wait" thing with no success. A similar thing happened a couple of months ago, and I resolved it by resetting the connection settings to factory defaults then reconnecting and re-entering the security key. That isn't working this time.
When I press Y on the failed test screen I get the following information:
D: 0.0.0.0 0.0.0.0
N: Name of router
Any help would be appreciated, as I just started a one month Gold trial last night, and frankly if that goes to waste then it's hardly going to entice me to maintain a paid subscription.
