I can not play games with friends anymore, I get disconnected from the parties and lobbies...

Didn't work, turn it completely off and unplugged it, tried joining and inviting my friend, same thing happened.

-

(I'll describe what happened)

I invite him to join, and he can't.

I disconnect connect from LIVE and repeat, still doesn't work.

We both turn off our modems and routers reconnect and repeat and he joins! But wait! There's more!

Now either after around 30 seconds or when I start the match he either gets disconnected from the lobby (only the lobby) or if I start it I get disconnected from LIVE (just says disconnected from LIVE every time), respectively.

So now we've both given up for tonight.

Funnily enough is that this has happened before, but every now and then we connect and can play.

We've never had problems when "partying up" in Minecraft or another game, it's just Call of Duty. It's annoying as hell!

(Oh this is the Spec Ops lobby, not online)

keep getting error 807B01F7/8072EE2 thought this was on my end but glad to see it not. i keep getting dropped outta games and parties. i can be in a game/lobby/party for 5 minutes before i get disconnected from all and end up in a pregame lobby SO FRUSTRATING.
also will this be fixed before double xp weekend. and i know a couple people have mentioned it already, but why am i paying for a service that doesn't work?

Just party up with the friends who are online already or start a party and invite them. When you start playing a mp game your friends in party will receive a pop up asking if they wish to join or if you are in the same game you will get brought in automatically
from lobby.

I am having the same issue and it's starting to make me become very agitated. Sporadic disconnects from XBox live when I am not actively playing an online game. If I am playing a single player game, Skyrim for example, within 5 minutes I am disconnected
from Live. If I am in a Party Chat I am disconnected from the chat but not Live. Then I have to reconnect to the Party. Or, my friend are booted from the party and not me...the party issues happen every 2-3 minutes or less sometimes. Starting to get very aggravating.

My Fiance and I have the same problem we cannot get into a Party or Game lobby. We have seperate XBL Gold accounts. We can both connect to live and even play the same games at the same time but we cannot be in the same lobby or party without one or other
of us being disconnected. We have found though that Halo Reach seems to be the exception, here we can party up and play with no problems so far this is the only game we have found that still allows us to this.
