It is typically caused by lag, you have been booted because it is taking too long to receive files or send files which is not necessarily your fault (although, in this case, i wouldnt be surprised if you are getting it repeatedly).
Make sure all other programs using the internet are turned off and a family member is not downloading while you are playing. Also, try to move closer to your router if you are on wireless.
Another thing, try unplugging your router/modem for a minute to refresh it... it can work wonders if you havnt done it in a good while.
hopefully that helps... if not...sorry
