What Is WPA3? Is Your Router Using It?
WPA3 is the current WiFi security standard that protects your wireless network. Here's what it does, why it matters, and how to check if your router supports it.

WPA3 (Wi-Fi Protected Access 3) is the current security protocol standard for WiFi networks, introduced in 2018 by the Wi-Fi Alliance. It replaces WPA2, which has been the standard since 2004 but has known vulnerabilities. WPA3 is now required on all new Wi-Fi 6 (802.11ax) certified devices.
Log into your router's admin panel (usually at 192.168.1.1 or 192.168.0.1). Go to Wireless Settings or Security Settings. Look for a security mode dropdown - options including "WPA3-Personal" or "WPA3/WPA2 Transition Mode" indicate WPA3 support. If you only see WPA2-PSK, your router does not support WPA3.
Use WPA3 if all your devices support it. Most devices from 2019 or newer support WPA3. If you have older devices (pre-2019 laptops, older smart home devices), use "WPA3/WPA2 Transition Mode" which supports both protocols simultaneously. Never use WPA, WEP, or "Open" networks - these are completely insecure.
Most routers released after 2019 support WPA3. Check your router's admin panel under Wireless Security settings. Wi-Fi 6 (AX) routers are required to support WPA3 as part of Wi-Fi 6 certification.
WPA2 with a strong, unique password is still adequate for most home networks. However, WPA3 is significantly stronger - particularly its resistance to offline dictionary attacks and KRACK. If your router and devices support WPA3, enabling it is recommended.
Use WPA3/WPA2 Transition Mode, which is offered by most WPA3-capable routers. This mode uses WPA3 for devices that support it and WPA2 for older devices. Your network is more secure than WPA2-only, and all devices can still connect.
WPA3 protects the wireless connection itself - it prevents attackers from cracking your WiFi password or intercepting your traffic in transit. It does not protect against router admin panel exploits, unpatched firmware CVEs, or attacks from inside your network. Both are needed.
