How do I Display Comcast Signal Levels on a Modem?

Comcast is a cable service provider throughout several different regions in the United States. In addition to providing cable television service, Comcast also offers cable Internet service. In order to access the cable Internet, it is necessary to install a cable modem, which is connected to a cable wall outlet via a coaxial cable and then connected to your computer with an Ethernet cable. If the Internet is running slowly on your computer, it is possible to check the signal levels to determine whether there is a problem with your cable Internet service.

  Verify that your cable modem is turned on -- there should be illuminated lights on the front panel -- and that it is connected to your computer or router.

  Click the "Start" or "Windows" button in the lower left corner of your screen, then select "Programs" or "All Programs."
