WPA3 security shortcomings
Those rules have security limitations, including a hacker's ability to guess your password. Changing to the new system may help, but it won't provide perfect protection. WPA3 shortcomings include: Ongoing security risks.
Windows 11 supports Wi-Fi 6 and WPA3.
WPA3 provides a more secure connection than WPA2, but many WiFi devices might not yet detect WPA3 and support only WPA2. Similarly, WPA2 provides a more secure connection than WPA, but some legacy WiFi devices do not detect WPA2 and support only WPA.
WPA3 comes as a successor to WPA2 - a wireless network security algorithm used in Wi-Fi networks. Its introduction dates back to 2018, and after July 2020, all Wi-Fi devices that are certified must support it.
Although WPA3 is supported by devices with Wi-Fi 6, it is not supported by many older wireless devices such as: Android mobile devices with Android older than version 10. Apple iOS devices with Apple iOS older than version 13. Apple Macs with macOS older than version 10.15 (Catalina)
Secondly, if you have an older router, but not too old, that can get WPA3 with a firmware update, you're in luck. WPA3 is a software-based upgrade over WPA2, and many routers can support it with firmware updates.
As unfortunate as it is, devices that support WPA3 are still not ubiquitous. While the number of WPA3-compatible devices is increasing by the day, many older devices, particularly those released before 2018, still don't support this advanced security protocol.
Explanation: It is recommended to use WPA2 or WPA3 encryption standard as they are strong and more secure. WPA2 & WPA3 characterizes the protocols a router & Wi-Fi client devices use for performing “handshake” securely for communication.
However, WPA3 and WPA2 requires more processing power than WPA to protect your WiFi network, so you need more powerful hardware. As for the data encryption speed, WPA vs WPA2 vs WPA3, WPA3 is fastest while WPA is the slowest.
Windows 10 does support WPA3, but your wireless adapter's driver doesn't(WPA3 is implemented by the driver instead of the OS, so OS update won't do anything to this). And Qualcomm should already stop the future driver update for your AR938x, so it won't support WPA3 forever.
As the most up-to-date wireless encryption protocol, WPA3 is the most secure choice. Some wireless APs do not support WPA3, however. In that case, the next best option is WPA2, which is widely deployed in the enterprise space today.
Stronger encryption
WPA2 requires a 64-bit or 128-bit encryption key. But WPA3 uses a 192-bit encryption security suite for protecting WiFi users' networks with higher security requirements, such as government, industrial organisations and defence. Better encryption is better for us all!
WPA3 incorporates Simultaneous Authentication of Equals (SAE), a secure key establishment protocol between devices. By using a stronger 'handshaking' protocol, users should be protected from password guessing attempts.
Longer Encryption Keys
Most WPA2 implementations use 128-bit AES encryption keys. The IEEE 802.11i standard also supports 256-bit encryption keys. In WPA3, longer key sizes—the equivalent of 192-bit security—are mandated only for WPA3-Enterprise.
In January 2018, the Wi-Fi Alliance announced WPA3 as a replacement to WPA2. Certification began in June 2018, and WPA3 support has been mandatory for devices which bear the "Wi-Fi CERTIFIED™" logo since July 2020.
The Wi-Fi Alliance mandates support for WPA3 security for the Wi-Fi 6 certification, meaning that all 802.11ax radios must support WPA3.
If compatible, you only need to update the firmware to enjoy WPA3 Wi-Fi with WPA3-supported devices—no need to purchase a new router.
Select Wireless. Under Security Options in the Wireless Network (2.4GHz b/g/n/ax) section, select WPA3-Personal. Under the Security Options (WPA3-Personal) section, enter a password for your network. Repeat this process for the Wireless Network (5GHz 802.11a/n/ac/ax) section.
WPA3 support is purely based on software. There is no dedicated hardware required to run either WPA version. This clearly states that WPA3 support for proprietary devices can be added with a firmware upgrade - which is purely software, and not a hardware feature.
WPA3 is supported on the following Apple devices: iPhone 7 or later. iPad 5th generation or later. Apple TV 4K or later.
Note: Currently, only AX series provides WPA3-Personal features, and both 2.4GHz and 5GHz bands support WPA3-Personal option.
The researchers found that even with WPA3, an attacker within range of a victim can still recover the password to the Wi-Fi network. The two flaws – downgrade attacks and side-channel leaks – can be abused to recover the password used by the Wi-Fi network.
