80151901 - Can't connect to Xbox Live.

anyone else getting this error? one minute I can turn my 360 on and connect right away, the next I'll try 5 times in a row and get this same error code. It's not my connection, because my laptop and wifi tv and phone all connect effortlessly, it's just the 360. And nothing I do seems to remedy it, I just have to wait, for instance it worked 3 days ago, I signed on fine. It didn't work two days. It didn't work yesterday at first, but after relocating it from a vertical stand up position to the horizontal position, it signed right into Xbox Live... I don't know if that was just a coincidence or if flipping it somehow woke it up. 

suffice to say this is beyond annoying.

This happened to me last night while I was in a game...I had to reset my router to get it working again. Also like yours, everything else stayed connected. It was just the console.

resetting my router worked the first time it happened, but isn't working anymore... there doesn't seem to be a solid fix for it :\

Was on playing Halo 4, got off to get food, came back and yeah this is what I got.

Didn't happen to me at all today, or recently. Maybe depending on where you are located??
