Whenever I play TF2 (Team Fortress 2) I will be ingame for about 30 minutes then it will all freeze.. I will DC. I look at my modem (which is not connected to router and is comcast high speed) And all the lights are on and indicate it is working fine. There is also no notification on my comp that internet is DCed. Yet when I open up my web browser, I cant load any sites... I reset my modem and I can play for another 30 minutes or so until it happens again. I just came back from a TF2 break and it used to run great on this same comp with that same router... but it is just recently I have had this problem.
