in SSID
Symptom:
When connecting to a Captive Portal SSID broadcasted by WiFi 7 access points running firmware v7.20, the browser displays a certificate warning after October 21, 2025.
This occurs because some APs did not automatically synchronize the renewed captive portal certificate.
Solution:
Reboot the affected APs.
After the reboot, the APs will refresh the captive portal certificate, and the browser warning will no longer appear.
