WiFi Connection

Hi

I have two iPhone and a WiFi network with Huawei EchoLife HG8245H5 modem. In this modem, SSID is in hidden mode (No broadcast). In this mode, my iPhone SE (1st) with ios 15.7 dos not have problem and connect carefully. But my iPhone 13 mini with ios 16.0.3 that I bought about 1 month ago, does not connect automatically and each time I must set it manually. For testing , I change my modem mode to broadcast and iPhone 13 mini connect carefully.

What is the problem? I must hidden my ssid and this is very bad for me to connect each time manually.

Thanks
