A laptop user reports that they cannot see the SSID or connect to their company's wireless network. Which of the following should the technician try FIRST?
The correct answer is C. Check the wireless on/off switch. When a laptop cannot detect any wireless networks, the simplest and most likely cause is a physical wireless on/off switch being in the off position. Checking physical controls before software settings follows the principle of starting with the simplest solution.

Why each option
When a laptop cannot detect any wireless networks, the simplest and most likely cause is a physical wireless on/off switch being in the off position. Checking physical controls before software settings follows the principle of starting with the simplest solution.
Checking OS wireless settings is a valid step but should come after verifying the physical switch, as a hardware-disabled adapter cannot be enabled through software alone.
Replacing internal hardware is an invasive, expensive step that should only be done after exhausting simpler troubleshooting options.
Many laptops have a physical toggle switch or keyboard shortcut (Fn key combination) that enables or disables the wireless adapter at the hardware level. If this switch is off, the adapter will not transmit or receive signals, making all SSIDs invisible regardless of OS settings, making it the first item to check.
Checking signal strength is irrelevant if no SSIDs are visible at all, which indicates the adapter is not active rather than a signal problem.
