You are able to turn the WiFi off by accessing the settings through the quick menu. Select the double arrows on either side of the screen and open the settings cogwheel.  

From here you are able to toggle the WiFi 'enabled' switch to off. This only temporarily disables the WiFi.  

If you would like to permanently disable the WiFi capabilities of your CommBox Classic please advise us before purchase.

 In this case, we are able to arrange for your panel AD board to be swapped with an AD board without WiFi capabilities. 

Please note that this will incur additional costs.
