How to Configure a Comcast Router

By Michelle Miley

Many people use wireless routers to connect several home or office computers together. Networked computers can share information and a single Internet connection. Although any appropriate router can be used, Comcast supplies primarily Netgear brand routers to its customers. New routers must be configured before they can be used.

Things You'll Need

  • Comcast Internet service
  • Netgear / Comcast router
  • 2 ethernet cables
  • Access to an electrical outlet
  • Computer

Step 1

Plug one end of an ethernet cable into the back of the cable modem and the other end into the input jack on the back of the router,

Step 2

Plug the second ethernet cable into the output jack on the router and into the ethernet port on your computer. Even though you are setting up a wireless network, a computer must be wired directly to the router while it is being configured.

Step 3

Plug the router into an electrical outlet.

Step 4

Boot the computer and open your Internet browser. Type "" into the browser's address bar and press "Enter."

Step 5

When the password screen pops up, enter the username "admin" and the password "password." Then press "Enter."

Step 6

The Set Up Wizard should now be open. Click on the words "Wireless Settings" on the left side of the screen.

Step 7

Under the "Security Options" heading, select the WEP setting.

Step 8

Select the automatic authentication type and choose 64 or 128 bit encryption strength under the heading "Security Encryption."

Step 9

Enter your router's WEP key in the "Key 1" box under the "Security Encryption Key" heading.

Step 10

Click "Apply" and close the Set Up Wizard.

Step 11

If necessary, configure your computer for wireless network access in the manner appropriate for your operating system. Some computers will automatically detect the new network and will ask you for the WEP key in order to connect to it.
