Securing Your Home Wi-Fi Router

Change the router's default admin password — many models ship with well-known factory credentials.

Use WPA3 (or WPA2 if WPA3 isn't available) for your Wi-Fi encryption, not the outdated WEP standard.

Rename your network so it doesn't reveal the router make/model, and choose a passphrase that isn't personally identifiable.

Keep router firmware updated — many routers can check and install updates automatically.

Set up a separate guest network for visitors and smart-home devices, isolating them from your main computers.
