Device: iPhone 17 Series
System: iOS 26.0.0
Wi-Fi: TKIP encryption protocol
Question: Unable to join the network

We have several products that are used by connecting to iPhone via Wi-Fi.

Recently, many customers who have purchased the iPhone 17 series have reported that they are unable to connect to Wi-Fi.

For Wi-Fi with TKIP encryption, after entering the password correctly to connect to the Wi-Fi, a pop-up appears stating "Unable to join the network.".

Only Wi-Fi with WPA2-AES can be used normally. Before that, during the iPhone 11 era or even earlier, the TKIP encryption method was in normal use. However, the new iPhone models were incompatible with it, which obviously caused great inconvenience.

I hope the engineers can fix this issue to support Wi-Fi with older encryption protocols.

I haven't received the iPhone 17 I purchased yet, so I cannot provide the diagnostic logs. I will attach the diagnostic logs once I receive it

Is this error happening when you connection the iPhone to a Wi-Fi accessory that you’ve created? Or are you seeing with a Wi-Fi hardware from some other developer?
