Step

Determine your router or gateway. Your manufacturer, model and number should be on the equipment. See Reference below for the list of Comcast supported equipment.

Step

Open your Internet browser.

Step

Enter the IP address in your browser’s address bar. This will bring up a pop up asking for your "username" and "password." For the Linksys WCG200, for instance, the IP address is http://192.168.0.1.

Step

Fill in the requested information. For a Linksys WCG200, the Comcast defaults are "username:" Comcast and "password:" 1234.

Step

Click on the tab marked "wireless" from your Gateway status page. This will take you to "basic wireless settings." On the toolbar, you will see a selection marked "wireless security." Click on the link.

Step

Set your Security Mode. The default for Linksys WCG200 is disabled. However, on the drop down menu, there are several options. The most common option is WEP (Wired Equivalent Privacy). Selecting WEP from the drop down menu will give you the option to have keys generated and then select which key you prefer. If you don't want to use a generated key, you can enter your own key so long as it fills up the space.
