iPhone 15 Pro Max and similar models are unable to connect to the AP configuration hotspot broadcast by an IoT oven equipped with the MediaTek MT7682 chip. The connection interface remains in a spinning/loading state indefinitely, preventing the completion of the device’s network provisioning workflow.

Based on log analysis, we suspect the root cause is as follows: During the connection authentication phase, the EAPOL packet sent by the MT7682 has a Group Key ID of 0, while the iPhone 15 Pro series does not support a Group Key ID of 0. This causes the encrypted DHCP Offer packet replied by the MT7682 in the subsequent DHCP phase to fail decryption, resulting in the phone never obtaining an IP address. The issue will not be triggered if the AP is unencrypted. However, we would like to know if there is a corresponding setting on the iPhone to enable support for this feature (Group Key ID=0).
