4.  Select "Modem Status."

5.  Select "Wireless Status" in the menu on the left sidebar.

6.  Select "2.4 GHz" or "5 GHz" according to your modem's wireless network setup.

The best available WiFi channel can change based on factors in your environment. The modem will looks for the best channel whenever you plug in the power cord — to refresh the best channel available, you can reboot your modem.
