I just bought my xbox 360 a few months ago. At first I was able to connect to xbox live easily. But for the past month my xbox stopped connecting to xbox live. I've tried everything on the support page concerning connecting to xbox live and just yesterday it worked. But today I tried to connect again and it didn't work, I tried what I did yesterday and it still didn't work. Would this happen because there is a problem with my xbox? Or is it just my wifi network?
