That looks like a standard log. You may want to edit out the 67.x.x.x IP, since that is likly your public IP. Need more info to help. Does it say your wireless is disconnect? Or can you just not get online? When you loose wireless, do you also loose internet on your wired connection? Is it websites? Or does it just happen when gaming? Also, port 57486? Are you running some kind of server? A mail server?
