Been asked to make a new thread for this... hopefully this is how you do it! Basically the same problem as seen here: http://forums.xbox.com/xbox_forums/xbox_support/f/9/p/335321/1757892.aspx
I moved house recently and ever since i did so my xbox hasn't automatically connect to Live like it always previously did.
In order to connect I have to 'test connection' which usually gets it connected straight away. Although it isn't the end of the world, it does get quite frustrating if you're in a hurry.
Another thing, when i boot up the console from time to time and try to connect to Live I see this error report - 80151901
Other things I should note are, I've got 'auto sign in' ticked and have tried deleting and redownloading my profile. Both methods haven't sorted my problem.
Be great to get any advice on how I can rectofy this.
Thanks in advance!
