How to Interpret the Reports:

  • Avoid the high device count channels. In this images, those will be Channels 1, 6 and 11
  • Take note of 2.4GHz channels (1 through 11) that are not listed because they have no routers broadcasting over them within your scan range. In this image those will be Channels 2, 5, 7, 9
  • If you're configuring your modem yourself, you want to avoid the channels of the top 5 WiFi networks besides your own. 
  • Your recommended channels will be those with the fewest or no devices on them, which are not adjacent to the top 5 WiFi networks next to your own.

10. REMEMBER: go back into the Settings and turn off the WiFi-Scanner to conserve your device's battery.
