- 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.
It’s better to reply as a reply, rather than in the comments; see Quinn’s Top Ten DevForums Tips for this and other titbits.

OK. I can’t do much to help you with on-the-wire Wi-Fi problems here on the forums. My general advice is that you file a bug report about such issues. In the case of Wi-Fi issues specifically, follow the Wi-Fi for iOS/iPadOS instructions on our Bug Reporting > Profiles and Logs.
Please post your bug number, just for the record.
Share and Enjoy
