why is my xbox 360 randomly kicking me out of parties?

As Vanessa said, if you're going through a wireless router, you're going to lose connection speed, regardless of how close your console is to the router.

The simple process of bit-packaging, encrypting, sending, decrypting, unpackaging, re-packaging, re-encrypting, sending through the air waves, re-decrypting, re-unpackaging, then converting is enough to really hamper a connection. By removing the router from the loop, you can avoid a lot of those unnecessary steps.

This is a known problem and Microsoft is presumably doing a patch. this happens to me, everyone i know at some point. Its just a minor inconvenience for the time being. The unable to join thing can be solved if you do a power cycle on you modem and router if you have one. Do a quick search for how to do it. And that should fix your problems. If it persists call Xbox at 1-800-4MY-XBOX, Its free.

It's probably not your xbox...it's either the server (which you can;t do anything about) or your home network. If you're running your connection through a router (wireless or hard-wired) they tend to reduce your signal strength and will lead to getting dropped from parties or lagged gameplay. Try hard-wiring your XBox directly into the cable modem and see if that helps.

well first get a good game after that check your conection in settings and stuff and make sure your live connection is good

Because you Have welfare internet, just kidding, maybe some one is stealing you're bandwidth!

Because no one likes you. Because you never bring anything.
