I was playing on xbox live the other day and ran into some kid that was trash talking to me. He told me that he had my IP address and that he was going to overload my router so that I couldn't play on xbox live. Within 30 minutes of him saying this, every match i tried to play was laggy to the point where I could not play at all. My connection was the worst it could be and it has been the same up until this day. My computer traffic has been fine which is also plugged into my router. Is this possible? If so, how can I fix it. Thanks a bunch!
