Modem Utilities Step 1-3

1.  Connect a device, such as a computer or tablet, to the internet through WiFi or using an Ethernet cable connected to your modem.

2.  Open a web browser and type into the web address field.

3.  Log in to the modem's online user interface (Modem GUI) using your Administrator Username and Administrator Password. Unless you have changed the default settings, you can find this information on the modem's sticker. Note that these are different from your wireless SSID and security key.

4.  Select "Utilities."

5.  Select "Wireless Diagnostics" in the left sidebar.

6.  Select a Wireless Tool from the dropdown menu. The list of diagnostic tools varies from model to model, so your particular router may not offer all of the options listed below. Click on the tool name to view a sample.

  • Shows you a list of devices connected to your WiFi network
  • AP Scans show you the access points (AP) near you, specific to 2.4 GHz or 5 GHz
  • Client Diagnostics gives you data specific to each device connected to your WiFi. This is helpful when one device is having WiFi problems.
  • Channel Analysis gives you data about available WiFi channels, including non-WiFi noise, noise from other access points, total channel noise, and channel rank. This can help you choose and set the optimal channel.
