How Do I Install My New Modem from Comcast?

Setting Up the Modem and Router

To set the modem up, follow these steps:

  1. Put the modem in a convenient location.
  2. Plug the coaxial cable into the cable outlet jack.

  5. Connect the Ethernet cable to the modem.
  6. Connect the other end of the Ethernet cable to the Ethernet port on the back of the wireless router.

  8. Connect another Ethernet cable to one of the four boards on the back of the wireless router.
  9. Connect the other end of it to the Ethernet port on your computer.
  10. Turn your computer on.
  11. Type your router's IP address into the URL field.
  12. Press Enter. You will be taken to an authentication screen.
  13. Enter the router's username.
  14. Enter the router's password. You will be taken to the router's setup page.
  15. Set the internet connection type to Automatic Configuration (DHCP).
  16. Enter a name for your new wireless network, its SSID.
  17. Save the settings.
  18. Go to the router's security page.
  19. Select your connection's SSID.
  20. Click on Connect. Your wireless router and modem will now be ready to use. You can disconnect the Ethernet cable between the computer and router.
  21. Open your web browser and check that everything is working properly.
