[quote name='LinkinPrime']See, thats's what I been hearing something about. Need to allow ports on router or something like that, but Im not technical in networking. How would I do that? Someone also mentioned to me to just reset the modem.[/QUOTE]
Try opening a browser window on your PC (it doesn't matter what browser you use, IE, Firefox, etc.), and type this into the address field:
192.168.2.1
That's the default IP address to access most routers. More than likely it'll bring up a username/password entry field. If you've never messed with the router settings before, more than likely both the username and password are "admin".
After that, you should be looking at the myriad of router settings. Look for something like "Port Forwarding". From there, you can tell the router exactly what ports you want it to open.
