Because this modem can operate the Wireless connection on two radio bands, you can choose which bandwidth you want to enable/disable the WiFi connection.
Note: WiFi 2.4GHz has better range in your home than 5GHZ. The primary differences between the two frequencies are the range (coverage) and bandwidth (speed) that the bands provide. The 2.4 GHz band provides coverage at a longer range but transmits data at slower speeds. The 5 GHz band provides less coverage but transmits data at faster speeds.
In the WiFi Settings section, click the WiFi 2.4GHz entry to access the 2.4GHz WiFi network settings, or click the WiFi 5GHz entry to access the WiFi network settings on the 5GHZ band.
In the Wireless Settings section, click the Disable button or Enable button to disable or enable WiFi connection.
Click on the Apply button to make the new settings active.
