Wi-Fi Setup for Homes and Offices

In this lesson you will

Choose good Wi-Fi settings
Secure a wireless network

Setting up Wi-Fi correctly the first time prevents most day-to-day connectivity complaints and keeps the network reasonably secure.

SSID (network name): Choose a clear, unique name so it's easy to identify among neighboring networks.
Router placement: Central, elevated, away from thick walls and metal objects gives the best coverage.
Encryption: Use WPA2 or WPA3 security (never "Open"/no password) to prevent unauthorized access.
Guest network: Many routers support a separate guest Wi-Fi network, keeping visitors off your main network where your other devices live.

Practical Skill: Set up (or review) a home or office router: rename the default SSID, set a strong WPA2/WPA3 password, and change the default admin password.

Practice exercise

Check your router's Wi-Fi security mode, channel and admin password, and list the changes that would make it more secure.

Key takeaways

Use WPA3 or WPA2-AES
2.4 GHz reaches further; 5 GHz is faster
