- The Wireless radio may have been disabled using a hardware switch in the PC. This feature is implemented by the PC manufacturers in different ways and may be a switch at the side or front of the laptop, button around the keyboard, or key combination.
- Wireless may have been set off using the icon in the Notification area of the desktop.
- The PC may be set to airplane mode in Windows, or the adapter may be set off from the OS.
This can be checked in the Charms menu, Settings, Network. Or by going to PC settings, Network pane, Airplane mode.
