Since a week ago, I can't play any mode that requires internet connection. The moment I join to track, my internet starts going slow and eventually, disconnects. It doesn't matter which mode I'm playing, free practice, qualyfing, race or time attack. Always happens. I don't know why, since all my PC games works properly, this one in special don't. I checked all my local archives and even updated Windows to it's last update, but the problem still getting on my nerves.
