not really sure what the problem is. i had it happen with another one of my friends but we were just buddies on live we werent real life friends. so i dont know what other fixes there are. its pretty stupid though.

YEah, I am getting the same problem with one of my friends...

It's quite annoying..Must be xbox live again.

Yup, me too.

Contacted Microsoft and they INSIST it's my ISP.

had the same problem as you! its ur router, my friend couldnt join my matches in gears of war, and someone told me it was because of my router, so what i did is just connect my xbox 360 directly to the modem, and BAAAM! i was able to connect with him againinfinitemurder

yah well thats not a solution nor an option for me. this is a old problem that shouldnt happen cough welcome to microsoft cough.

I get the same thing. Its completely random. One day we will be able to play Gears, CoD4 while in private chat together...the next he gets errors and cant join my party in CoD 4 or cant connect to my Gears game. Its got to be live cuz we are fine other days and I do nothing to my settings.

I'm taking this time out to help everyone having this problem just because i'm an all around nice person.

Well... I have been trying to fix this problem for about two years now and i still have not found a solution. =(

The problem is in your router. I know this because i can connect my xbox directly to my modem with the ethernet cord. I have a wireless linksys router with a model number of WRT54G. I'm guessing people having this problem have the same kind of router. Tomorrow i'm throwing the darn thing out and buying a router that is not a linksys. Everyone else is better off doing the same thing to save all the technological headaches and all the time you are going to spend, not to fix your problem. So write your complaints and throw the bastard linksys router away.

I have a buddy with the same problem, seems like it only affects a few people on his friends list. The BRAND of router should have nothing to do with it. Linksys, Dlink, Netgear etc... shouldnt matter. Im wondering if its something more buried like the amount of hops from one player to another.

There are so many points of failure in between networ points that its tough to nail down. My buddy has tried a new router, went from Linksys to Dlink and still didnt solve it. Id hate for someone to ditch a perfectly good router and not have their issue resolved.:!
