In the past month I have begun to lag ridiculously even though none of my settings have changed. It's on every game and it's to the point where I can't play online because I lag so badly that games kick me and even if they don't I can't do anything anyway. I can't even talk to my friends because the chat lags as well.
I am using a wireless adapter and my connection is all four bars. On top of that everything on xbox live is very fast. I can download games and videos very fast and stream things on netflix flawlessly. The only issue is when I encounter other people either on a game or in a chat.
My NAT type is open and I have port forwarding set up for all of the ports that microsoft recommends. I also play late at night which is a time when no one else in my house is on the internet and the time when it seems to be the fastest.
That's a speed test I did and from what I've heard that should be far beyond what I need to play on xbox live. I think I covered pretty much everything so my question was if anyone knows why I get this ridiculous lag?
