What is Wi-Fi?

Wi-Fi is a wireless technology that lets devices connect to the Internet and to each other without using cables.

How Wi-Fi Works

A router sends out a wireless signal. Devices like phones and laptops connect to this signal and share the Internet connection.

Things That Affect Wi-Fi

• Distance: The signal weakens farther from the router.
• Walls: Thick walls block the signal.
• Interference: Other devices can slow it down.

Staying Secure

Always use a strong password on your Wi-Fi. Use WPA2 or WPA3 security so others cannot use your connection.

Why It Matters

Wi-Fi makes the Internet available anywhere at home, school or work. It is one of the most useful technologies of modern life.
