Iv had this problem for about 3 weeks. Iv had Xbox Live for about 2/3 years now with no problems. It started off with my Xbox taking forever to sign me in, but it would then just instantly disconnect me from Xbox Live, but there was no message that popped up with an error, I then went on holiday and left it to see if it would sort itself out, however the new system update was released while i was away. When i came to turning my Xbox back on it still took forever to turn on and attempt to sign me in but because i couldnt sign in i couldnt download the update. I eventually updated using a USB but now when i come to sign in it takes a long time then disconnects me instantly and gives me the error message below;
Your console can't connect to Xbox Live. Do you want to exit this session and test your network connection? If you are playing a game, you will lose any unsaved progress. 880151911
Iv tried loads of stuff already as iv stated below. I cant delete my profile anymore so i cant re-download it because it says this action cannot be performed, i have no idea why its doing that either.
