Windows 11 will no longer allow connections to Wi-Fi WEP and TKIP
WEP is an encryption protocol in the IEEE 802.11i standard. The full name is Wired Equivalent Privacy. The meaning of the name is that wireless also provides confidentiality like wired. TKIP is an alternative security protocol in the IEEE 802.11 standard. The full name is the Temporal Key Integrity Protocol, which is used to replace the WEP protocol with security weaknesses. These protocols were released in 2003 and 2012 respectively, but both WEP and TKIP have been found by researchers to be vulnerable to eavesdropping. Therefore, based on security considerations, most new routers have completely phased out these encryption protocols, and the operating system and software are also gradually abandoning this protocol.
According to the support document released by Microsoft, since Windows 11 Build 22557, the system no longer supports connecting to WiFi encrypted by WEP and TKIP. In fact, Microsoft has listed this protocol as deprecated since Windows 10 v1903, and Microsoft said at the time that this protocol may not be supported in the future.
Currently, when users use Windows 10/11 to connect to WiFi WEP/TKIP, a warning message will appear to remind users that they should upgrade the router and encryption protocol. It is expected that starting from the new version of Windows 11 released this fall, Microsoft will officially deprecate the WEP and TKIP protocols, and if they continue to use this protocol, they will not be able to connect to the Internet. Microsoft reminds home users and business users who still use these insecure encryption protocols to replace routers as soon as possible.
At present, the latest security encryption protocol is the WPA3 version, which is already supported by new routers, and the WPA3 version is used by WiFi by default. Slightly older routers usually support the WPA2 version, and this protocol can continue to be used without being affected for the time being, but very old routers may not support it.
