I recently built a new computer and I bought Call of Duty 4 for it. I immediately started playing online and it ran amazingly. Little or no lag ever, it was great. A couple days ago, my mom unplugged our router and modem to do some cleaning, and when she plugged it back in, I logged into CoD4 online and TRIED to play. Playing online was like a slide show. I already tried resetting modem and router and such, does anyone have ANY ideas on how I can maybe fix my connection? We have highspeed, and I've never had a problem with lag before. Any suggestions would be great!!
