Bug causes macOS Big Sur to incorrectly display "WPA/WPA2 weak security" warning after upgrading to 11.2

Anyone encounter this issue after upgrading to 11.2? I've had never noticed the problem on 11.0.1 and 11.1.


Everything looks OK since my wireless network is set to WPA2/WPA3 standards as expected. Sounds like a bug.


Mac mini 2018 or later

After hours of research I finally found the culprit: the Speedport Plus settings were set to WPA/WPA2. I switched to the more secure WPA2 encryption scheme and the warning message disappeared.
