I have Comcast internet and I need a play by play on how to set up my wireless router so I can have WiFi. It did not come with a CD. I know I have to go to 192.168.1.1 and such and the default user name is password and the password is password or 1234 but it doesn't work and I'm not even 100% sure I have the wires set up right. I have also downloaded the manual but it says setup Netgear router using setup wizard. My router model is Netgear n300.
