I have been having a weird problem with xbox live since i changed my internet. I now have cable from service electric. I use to have DSL. Ever since i changed to cable i have been getting disconnected from live anytime my two friends who live on the same block as me join. They both use the same internet provider.
I have attempted to make a static IP address which i thought would help but it has not. I have unplugged my modem for 30 seconds and restarted but that does not work either.
I am currently connected with a Motorola model SBG6580-G228. My connection to my xbox is wired. I never had this problem when i had DSL. I only get disconnected when i am in a game or chat with these two friends. I can play with many other people. Its weird.
