Uhm, your cable modem has a single ethernet port for WAN. That gets plugged into the single WAN port on your router. There should be four more LAN ports on the router. Your PC plugs into a LAN port.
only[/B], wait for modem lights to come to a ready state
4. ensure ethernet from modem is in the routers WAN port, then power up the router
5. wait for router to come ready, ensure the PC is plugged into a LAN port on the router, and boot the PC
6. If windows, open a command prompt and type: ipconfig /all
In there, look for your IP, and look for the default gateway, the default gateway is your router's IP
Put that IP into a web browser and you should hit the router's config page, but you'll a login for it.
I have internet but I still can't access the router config page at 192.168.0.1. It shows a blank page, but nothing else.
Tried https://192.168.1.1/ in IE and Firefox. Both said "Problem cannot display webpage."
Tried http://192.168.1.1 without the "s." It shows a window that says "Authentication required." I guess that's the config page, but it's password protected, right?
admin/blank password is usually the default
