How to Enable WPA3 on Your Router

Understand WPA3 before you change settings

WPA3 is the current Wi-Fi security generation. It offers stronger authentication, more robust encryption, and it is mandatory for Wi-Fi CERTIFIED devices. WPA3 networks use the latest security protocols, disallow outdated legacy protocols, and require Protected Management Frames. This makes them a stronger choice than WPA2 for most home networks.

The Wi-Fi Alliance describes WPA3 as simplifying Wi-Fi security while enabling more robust authentication and delivering increased cryptographic strength for sensitive data markets. For home users, the practical benefit is that WPA3-Personal adds stronger protection against password guessing attempts. If your router supports it, switching to WPA3 is usually a good next step. You can read more in WPA3 explained.

Find the wireless security menu

To turn on WPA3, start in the part of the router interface that controls Wi-Fi security. On many routers this is called Wireless, Wi-Fi, Security, or Security Mode. If your router has a companion app, the same settings usually appear in the app under Wi-Fi settings. On routers with separate menus for the 2.4 GHz and 5 GHz bands, check whether the security mode is configured separately for each band.

Open the security settings and look for a security mode or security type menu. A router with WPA3 support will list an option called WPA3-Personal, WPA2/WPA3 mixed, WPA2/WPA3 transition, or sometimes WPA3 as the only personal option. Some routers place the WPA3 setting in a more advanced security section. If you cannot find it, look at the router model number and the current firmware version before you decide the router does not support WPA3.

• Log in to the router interface using your admin credentials.
• Open the wireless setup, Wi-Fi, security, or wireless security page.
• Look for a security mode dropdown or radio buttons.
• Choose WPA3-Personal or WPA2/WPA3 mixed mode.
• Enter a secure Wi-Fi passphrase if it is not already saved.
• Save the changes and allow the router to restart the wireless radios.

Choose WPA3-Personal or WPA2/WPA3 mixed mode

WPA3-Personal is designed for networks that use a shared passphrase. It increases protection from password guessing attempts compared with earlier personal Wi-Fi security. WPA3-Enterprise uses higher-grade security protocols for sensitive data networks, so it is more relevant for businesses than for most homes.

WPA2/WPA3 mixed mode is a useful transition setting. It lets older devices continue to use WPA2 while WPA3-capable devices connect with WPA3. Use it as a temporary step, then move devices to WPA3-only once they are compatible. If every device you own supports WPA3, choose WPA3-Personal to get the strongest protection. For more background, see WPA3 transition mode vs WPA3-only.

Check device compatibility before you switch

Before selecting WPA3-only, confirm that each device on the network supports WPA3. Current Wi-Fi CERTIFIED devices include WPA3, but older phones, laptops, smart home gadgets, and some printers may not. WPA3 networks use the latest security protocols, disallow outdated legacy protocols, and require Protected Management Frames. If a device cannot handle those requirements, it will not connect to a WPA3-only network.

Try updating the device operating system, drivers, or firmware first. If the device still cannot connect, use WPA2/WPA3 mixed mode until the device is replaced. For help with connection issues, see WPA3 device connection failures.

If your router does not offer WPA3

First update the router firmware. WPA3 support is sometimes added to existing routers through firmware updates, so check the router maker's support page for the current version. After updating, look through the wireless security menu again. If the menu still shows only WPA2 or older options, the hardware may not support WPA3.

The most direct fix is to replace the router with a current Wi-Fi 6 or Wi-Fi 7 model, since WPA3 is mandatory for Wi-Fi CERTIFIED devices. Compare options in the Wi-Fi 6 router guide or the Wi-Fi 7 router guide.

Save changes and reconnect devices

When you save the security setting, the router will usually restart the wireless radios. Every device on the network will drop for a few seconds and then reconnect. Some devices may ask for the Wi-Fi passphrase again, especially if you changed from WPA2 to WPA3. Enter the same passphrase you configured in the router security menu.

After the devices reconnect, you can check the network details on a phone or laptop to confirm which security mode is active. Many clients display the security type next to the network name. If you see WPA2/WPA3 or WPA3 listed, the router is using the new mode. A device still connected with WPA2 does not mean WPA3 is broken; it likely means that client does not support WPA3 and is using the transitional mode.

Keep other security habits strong

WPA3 is a strong foundation, but it is not the only setting that matters. Keep the router admin password unique, change the default login if you have not already, install firmware updates, and disable services you do not use.

NIST publishes cybersecurity standards, guidelines, and best practices for networks, identity, and access management. The same layered approach applies at home: use a long Wi-Fi passphrase and review the devices connected to your network from time to time. See router security basics and how to change the router admin password for more.

What to pick for your setup

If your current router supports WPA3, enable it in the security menu before you shop. If you are already looking for a new router, choose one from a current Wi-Fi generation and check that the spec page lists WPA3. Most routers designed for modern homes, gaming, or mesh systems will include WPA3 support.

For a small home, one Wi-Fi 6 router is usually enough. For a larger home, a mesh Wi-Fi system lets you apply the same security mode across all nodes. Use the table below to match your situation to the relevant buying guide.

Questions

Does enabling WPA3 slow down my Wi-Fi?

WPA3 focuses on authentication and encryption. It does not change the advertised speed class of your router. When you switch to WPA3, devices may need to reconnect, but the security protocol itself should not lower your internet speed.

What if older devices cannot connect after I enable WPA3?

Use WPA2/WPA3 mixed mode to let older clients stay on WPA2 while newer devices use WPA3. Also update the device operating system, drivers, or firmware. If the device still cannot connect, it may need to be replaced.

Can I enable WPA3 on any router?

Only routers that support WPA3 will show the option in their security menu. A firmware update sometimes adds WPA3 support to an existing router, but if the hardware was not designed for it, you will need a newer router.

Is WPA3-Personal better than WPA2-Personal?

Yes. WPA3-Personal adds stronger authentication and is mandatory for Wi-Fi CERTIFIED devices. It also requires Protected Management Frames, which helps protect against some types of wireless attacks.

Do I need WPA3-Enterprise at home?

Most homes do not need WPA3-Enterprise. WPA3-Personal gives strong protection for a network secured by a passphrase. WPA3-Enterprise is designed for organizations that need higher-grade security protocols for sensitive data networks.

Can I run WPA2 and WPA3 at the same time?

Yes, through WPA2/WPA3 mixed mode. This lets older WPA2 devices and newer WPA3 devices connect to the same network. WPA2-only devices continue to use the older security level, so use mixed mode as a transition rather than a permanent setup.
