Wrong Kind of Ethernet Cable?

Try this: reset your router to the factory settings by holding down the reset button while the router is plugged in for 30 seconds. Once it's done, your default username and password will be admin. Connect your router to a computer via ethernet cable, open internet explorer, firefox, safari, etc. doesn't really matter which browser you use and type in the address bar 192.168.1.1 and press Enter. it will ask for a username and a password, type admin for both.
Now you have accessed your router(don't worry about the CD). Go to wireless and then wireless security and select WPA2 Personal as your encryption type then choose a password, it's has to be at least 8 characters long(letters, number or both). Hit Save settings on the bottom. You now have a secured wireless network. Connect your cable/DSL modem to your router, reset the router by unplugging it and plugging it back in and wait till both your modem and router are up. Now try to connect and you should be able to go online :)
Good luck and let us know how that worked out for you ;)

Step 1:
Connect the broadband modem to the router's WAN or Internet port.
Step 2:
Connect the computer to any available numbered port (1, 2, 3 or 4).
NOTE: In this example, we'll connect the computer to port number 3.

NOTE: It is advisable to connect the computer to one of the Ethernet (1, 2, 3 or 4) ports when setting up the router for the first time.

Hello friend,
i guess that you are talking about wireless code, in this case you will need to connect the laptop to the router via Ethernet cable to configure it and then unplug the cable and use the wireless.
so you connect the ethernet cable between the laptop and one of the ports on the router from 1 to 4. then access to the router web interface which is usually 192.168.1.1. then go the wireless tab and name your wireless access point and put a password to secure your network. After that you can unplug your Ethernet cable and use the wireless on your laptop to connect your router wirelessly.
Best Regards,

set the printer up manually with a static IP address. To do so, go to the setup menu under network settings and select manual.

First try connection the Yellow ethernet cable from the rca modem to your computer's network connection. If you get a connection this way, then your modem will work with a ethernet cable. If not, then call Comcast for help. The modem ethernet out to computer port must be connected to the wan line of the router. Then you can connect an ethernet cable from your computer network connection to one of the 4 ports of the router. For wireless connections you must set up the router and wireless adaptor with the same settings to connect. Follow the routers directions.
Good Luck

Hi!

Try these steps:

1. Make sure the wireless is disabled when you're doing that. It might cause a confusion between the wired and wireless connection.
2. Try to plug it at other ports (1-4)
3. Try another known working ethernet or CAT-5 cable.
4. Set the laptop's LAN card's speed to 10-hald duplex.

Try these and hope it will help you ;-)
