So I installed Modern Warfare 2 and it is asking me to open up my NAT and enable UPnP. I went to the site Infinity Ward asked me to and yeah. I clicked on the site for my router and it asked me to type my router IP into the browser, so I did. After I typed it, I tried clicking the buttons on the top and it needed a User and Pass, so I exited that and searched some more. On the search engines, it told me to go into my router and change some stuff up. Ex: type in CMD on your PC search thingy and blah blah blah. I did that but I don't want to ruin my router for my family.
I play Modern Warfare 2 on Steam (PC).
