I cannot guarantee this will work for everyone, but it did work for me. My connection to this game has been all kinds of messed up since the update done on October 28th. All I would receive were error messages, CATERPILLAR and HAWK to be exact, then I would get booted from XBL completely. This would occur every 10 - 15 minutes. The only time it would not happen were the early morning hours, between 3:00 - 5:00 AM, EST. My ISP is also Comcast. I do not know if ANY of this info helps, but here is what I did. I went to the CONFIGURE NETWORK settings on my Xbox 360. I set the options to Auto and ran the test. I then wrote down ALL the info as it was. IP ADDRESS SUBNET MASK GATEWAY PRIMARY DNS SECONDARY DNS The next thing I did was changed the Auto Configuration to Manual and ONLY EDITED THE IP ADDRESS. If my IP ADDRESS was 10.0.0.10, I simply changed it to 10.0.0.15 The last sequence of numbers were the only ones I changed. You can change them from 2 - 240. So play around with it. Chances are, if you are on here looking for a solution, you have the time to try a handful of numbers. The reason why I wrote down everything else was so I could change them back to what they were in manual mode. I [b]DID NOT[/b] have to call my ISP, and I [b]DID NOT [/b]have to buy a new router, and I [b]DID NOT [/b]have to log into my router to do this. I doubt this is a permanent fix, but should allow SOME to enjoy the game until Bungie does what needs to be done on their side. I did, however, experience new error codes, such as GROUNDHOG and JACKAL which booted me back to orbit, but no disconnect from XBL. If this does not work for you, I am sorry. If this does work for you, then awesome. Good luck to those who need it.
