For Windows Based Computers

If the drivers for the wireless adapter contain a setting to toggle wireless radio, it can be located using the

following path: Start > Settings > Control Panel > Right click Wireless Network Connection Icon > Properties >

Configure > Advanced tab

Here you will find a textbox with a list of selectable properties that are populated by the device driver. Once you

select a property there will be a value field with a dropdown box containing configuration options that apply to that

specific property. The name of the wireless radio property may vary because the listed properties are dependent on

each specific device driver. It should be fairly intuitive to determine the correct property if you simply have the user

read all the listed properties to you.

Many laptop manufacturers will place a physical switch on the outside casing of the laptop, so that the user can

easily toggle wireless radio. Sometimes these switches get accidentally turned off, or intentionally turned off and the

end user forgets to switch it back. The best practice in these situations is to ask the user to look for a physical switch

on the case of the laptop, possibly with a symbol of a radio tower next to it. After turning the wireless switch on, the

user will probably need to refresh their network list.

Laptops built by certain manufacturers may have a specific keystroke set up to toggle wireless radio.

Below are some examples of wireless radio software and hardware toggles that we have been able to
