I'm on Xbox live but it won't let me talk or join parties it says connection lost but I run the test for my connection and everything is fine?? Help

Find Official EA and DICE Servers on Battlefield 3, You should make sure that you are
not connected to a Rented Battlefield 3 Server that normally has a very poor internet service, Attempt a DICE Server on Battlefield 3.
When you have done this keep us updated ^_^

Well ur not the only one after i came from school i couldn't join xbox live well few hours later it let me in but won't let me join any parties game's anything when i try to use app it give's me some kind of 800100 error or something like that.

How can you keep playing? I can't search for or join any matches. I do have a Live subscription, and I'm connected RIGHT NOW. I'm so sick of this.

Before the last update, I waited upwards of 10-15 minutes to find a match, had uneven teams, and got booted halfway through games.

This update was supposed to fix multiplayer. Instead, it won't even let me in. 343 and Microsoft laid a big turd with this multiplayer functionality (or lack thereof).

This still doesn't work. By the time it works properly, the lobbies will be empty.

I've got a similar problem with instant on that won't let me join parties or anything when it first turns on. It also won't give me a NAT type until I test the connections and even then gives me errors sometimes. I usually have to restart the console and
then it's fine. (Xbox One S 2TB)
