I'm sure you will ask for more information, but this is what I have for now.
Last time I played everything worked great.
As of today, everytime I connect to Live I get disconnected.
My connection will last from 3 seconds to a few minutes.
I'm not losing my internet connection, that much I know. Everything else is running smooth.
It is a console or Live issue.....must be.
Like I said, nothing has changed since last use. I have a tested and scorching fast internet connection.
Done the basics....re-set modem / router etc.
