How to Enable WPA3 Encryption
WPA3 is the current standard for Wi-Fi security. If your router and devices support it, enabling it takes under two minutes and meaningfully improves your network protection.
What Is WPA3 and Why Does It Matter?
WPA3 (Wi-Fi Protected Access 3) is the Wi-Fi security protocol that replaced WPA2. It was introduced in 2018 and addresses several known weaknesses in WPA2, particularly around offline dictionary attacks against captured handshakes. With WPA2, an attacker who captures the connection handshake can attempt to crack your password offline at their leisure. WPA3's Simultaneous Authentication of Equals (SAE) eliminates this attack vector entirely.
WPA3 also introduces Forward Secrecy, which means that even if someone captures your encrypted traffic today and later cracks the password, they cannot retroactively decrypt the captured data. This is a meaningful protection improvement for anyone on a network where others might be passively capturing packets.
If some of your devices do not support WPA3, set your router to WPA3/WPA2 Transition Mode (sometimes called WPA3-Personal Transition). This allows WPA3 devices to connect with WPA3 while older devices use WPA2 — no devices are left out.
How to Enable WPA3
Go to http://192.168.1.1 in a browser. Enter your admin credentials.
Look in Wireless > Security, Advanced > Wireless Settings, or similar. You need the security mode or encryption type dropdown.
Choose WPA3-Personal if all your devices support it. If you have older devices (pre-2019 phones, some smart home devices), choose WPA3/WPA2 Transition Mode or WPA3/WPA2 Mixed Mode instead.
After saving, devices will disconnect and need to reconnect. Most modern devices connect automatically. Older devices may need manual reconfiguration.
WPA3 Compatibility
WPA3 on the router requires client devices that also support WPA3. Devices that do not support WPA3 will fail to connect if the router is set to WPA3-only mode. Use Transition Mode to support both.
| Device Type | WPA3 Support |
|---|---|
| Windows 10/11 laptops (2019 or newer Intel/AMD Wi-Fi adapter) | Yes |
| iPhone 11 and later (iOS 14+) | Yes |
| Android 10+ devices with Wi-Fi 6 or newer | Yes |
| Mac with Apple Silicon (M1/M2/M3) or 2018+ Intel Mac | Yes |
| Smart home devices, older IoT sensors | Usually No — use Transition Mode |
| Devices before 2019 | Unlikely — use Transition Mode |
FAQ
Will WPA3 slow down my Wi-Fi?
No, WPA3 does not reduce throughput. The authentication process is slightly more computationally intensive but this happens only at connection time, not during data transfer. You will not notice any speed difference in practice.
My router does not show WPA3 — how can I get it?
Routers sold before 2018 do not support WPA3. Some 2018-2019 routers received WPA3 support via firmware update. Check your router manufacturer's support page for a firmware update. If no WPA3 firmware is available for your model, a hardware upgrade is the only option.
