I have sprint mobile broadband. Its the old one where you can use any router with and not just a sprint router. The way i have it set up is that i have my sprint card connected to my computer through usb of course. Then i have my router hooked up to the back of my computer and then the other Ethernet cords from the back of my router going to various things such as my ps3 and xbox. I cant' connect to my router by typing in the IP in the address bar. Why is this? My NAT type is Moderate on MW2 but i can't open ports cause i can't get into my router configuration.
