First Off I am using Windows 7 and familiar with opening ports. I am trying to play Dirt 2 on Steam on Windows Live Games. I have connected online in Dirt 2 before via router but for some reason now it wont let me(6 months later) unless I directly connect from my modem. I have opened all ports from 1 - 9999 on my ip4 address and still no avail and even dmz and still doesnt work. I was thinking of trying a firmware upgrade but I am unsure how to do it on the linksys website it asks me to specify my version number which I dont know how to find. Or is there some other solution to this? Thanks.
