Disconnected from Game

I log in and started to play and everything works find. My ping is good and all of a sudden there is internet disconnection. Thing is, I have constant internet connection. While the client says that I don't have internet connection, I'm able to browse the net just fine.

I restarted the client, restarted the computer, connected to the modem directly and run the client as admin. It load up but as soon as I reach 100% it says I have been disconnected from game.

I'm connected to NA. I don't know what else to do. Maybe it's because the servers change but I have good ping.

What can I do?
