Hi alzhao, thank you for your fast replay.
Because I have activated “WPA2-PSK/WPA3-SAE” (192.168.8.111) in the private WLAN and all devices except my camera recognize “WPA2-PSK/WPA3-SAE”. However, the camera only sees the WLAN 2.4Ghz with “WPA2-PSK” (192.168.9.123). I therefore had to create a guest WLAN 2.4Ghz that is set to “WPA2-PSK”.

My camera connects to the guest WLAN 2.4Ghz (192.168.9.123), which works. But I would like to access the camera with the browser and that is not possible because it is connected to the guest WLAN.
