When I join a mate's XBOX party, it occasionally disconnects people from that party until I...

This would be great, especially when you get mutliple achievements at once, send your friend a party invite and an invite to join the game, they join the party, you get disconnected from live, reconnect, rejoin the party.

I could easily cut down my friends list without feeling guilty about removing people. (Although there'd still be that sadness when you realise someone's missing).

I've also been experiencing these problems such as when I join a party it lets me join yen disconnects me from the party the then from Xbox live its only been happening for a few weeks and I've called to check with my ISP and they told me that nothing was
wrong.

That is not the issue. He is on xbox and can talk normally until I join the party from my pc, at that point he can no longer hear people and people cannot hear him. I however can hear people and they can hear me. It is just one person that cannot use party
chat if i join on my pc.

It disconnects me from Live without a code.

The Ethernet cable is brand new, and so is the router.

All external devices have been removed.

Corrupt data removed.

Cleared cache three times and then power cycle

Still, when playing a game, I will receive a party invite, or private chat and if I try to join, I will join, talk for a while and then be kicked from party, and then eventually disconnected from Live.

Once I was able to stay connected to a party, but then I was disconnected from the EA servers while playing NHL 15.

It's still doing this.. all over the weekend, every time I joined a party or my friends joined my party I got disconnected from live and had to sign back in to live, once signed in it was fine..

I don't have this issue on the XO, I can join party's, or have friends join my party and it's fine..
