OK,
Maybe someone has had this problem or knows of a solution but as of now I am out of ideas.
My brother who lives in Texas "has Comcast internet" and myself "In aurora on Comcast Business class" have all of a sudden started having issues connecting to party chat and also to each others games. The ONLY thing that has changed was I had Comcast change my speed tier. Same modem, same wired connections to router, and such.
I have been through both of our routers and double checked all ports and even went the DMZ route for the Xbox's at both ends so they would be wide open.
We can not join each others games, can not join a party he creates and he can not join mine, If one of our friends makes a game we can join the game and play and such but as soon as the 3rd party leaves we loose connection.
Strange thing is my router went to a different IP range and on test sites it shows my location as South Bend, IN.
Comcast says connection is fine, Xbox tech says its Comcast back and forth.
Any ideas would be appreciated.
