What Is WPA, WPA2, and WPA3?

by Priya Nakamura Updated Apr 12, 2026

WPA (WiFi Protected Access) is a family of security protocols that encrypt your WiFi network to prevent unauthorized access. WPA3 is the latest and most secure version.

WPA vs WPA2 vs WPA3

WPA was introduced in 2003 as a replacement for the insecure WEP protocol. WPA2 followed in 2004 with stronger AES encryption and has been the standard for almost 20 years. WPA3, released in 2018, adds protection against brute-force attacks and improves security on public networks.

Which Should You Use?

Use WPA3 if your router supports it, or WPA2-AES as a minimum. Never use WEP or WPA-TKIP — they can be cracked in minutes. See our guide to enable WPA3.

Pro Tip: Understanding the OSI model isn't just academic — it helps you troubleshoot by isolating which layer a problem occurs at.

Key Takeaways

Private IPs (192.168.x.x, 10.x.x.x) are used inside your home network
DNS translates domain names to IP addresses
DHCP automatically assigns IPs so you don't have to
Your default gateway is your router's IP address

Frequently Asked Questions

What is the difference between WPA2 and WPA3?

WPA3 provides stronger encryption, protection against offline password guessing attacks, and better security on open networks compared to WPA2.

Is WPA2 still secure?

WPA2-AES is still considered secure for most home networks, but WPA3 is recommended if available. Avoid WPA2-TKIP.
