Frequently Asked Questions
Why is WEP considered insecure?
WEP uses weak RC4 key handling and short initialisation vectors, so keys can be recovered from captured traffic in minutes. It has been replaced by WPA2 and WPA3.
What is the difference between WPA2 and WPA3?
WPA3 replaces the pre-shared key handshake with SAE, which resists offline guessing, and adds stronger encryption and protected management frames. WPA2 is still common but more exposed.
What does 802.1X add to Wi-Fi security?
802.1X with EAP authenticates each user or device individually, usually through a RADIUS server, instead of sharing one password. This free Codelivly room covers it in WPA-Enterprise.
