01.Critical Router Settings
Access your router (usually 192.168.0.1 or 192.168.1.1) and check:
Disable WPS (Wi-Fi Protected Setup)
WPS is a massive security flaw. It allows intruders to discover your password in minutes via PIN brute force.
Use WPA3 or WPA2-AES
Never use WEP or WPA-TKIP (they are obsolete and insecure). If your router supports WPA3, enable it.
Don't do it Manually.

02.Guest Network and IoT
Smart devices (bulbs, Alexa, fridges) often have weak security. If a hacker breaks into your smart bulb, can they access your PC?
Yes, if they are on the same network. The Solution:
- Create a Guest Network on the router.
- Connect all visitors and IoT devices to this network.
- Most routers isolate the guest network from the main network ("AP Isolation").
Don't do it Manually.
