I am experiencing issue - Phone16 cannot to connect to WPA3-Enterprise Transition Mode SSID on Wi-Fi 7 AP. While iphone17 do not have this issue. And I have already created ticket - FB20924263.
Here are the details below: Product: iOS 26.1, Device Models: iPhone 16 (fails), iPhone 17 (works) Network: Wi-Fi 7 AP, 2.4 GHz and 6 GHz disabled, only 5 GHz enabled Feature Area: WPA3-Enterprise Transition Mode connectivity
Expected Behavior:
Both iPhone 16 and iPhone 17 running iOS 26.1 should successfully connect to a WPA3-Enterprise Transition Mode SSID when configured according to the standard.
Actual Behavior:
iPhone 16 (iOS 26.1) fails to connect to the SSID.
iPhone 17 (iOS 26.1) connects successfully under the same conditions.
Steps to Reproduce:
Configure a Wi-Fi 7 AP:
Disable 2.4 GHz and 6 GHz bands, keep only 5 GHz active.
Add an SSID using WPA3-Enterprise Transition Mode.
Attempt to connect with iPhone 16 (iOS 26.1) → fails.
Attempt to connect with iPhone 17 (iOS 26.1) → succeeds.
Additional Notes:
When I disable 11be mode and make the DUT run under 11ax mode, then iPhone16 can also connect to the WPA3-Enterprise Transition Mode SSID
As I’m a WiFi router developer, then I did one more thing, keep DUT under 11be mode, but do not enable MLO for that SSID (Remove MultiLink relate IE in beacon), then iPhone16 can also connect to the WPA3-Enterprise Transition Mode SSID
It seems Iphone16 with Broadcom wifi chip solution has some specific policy for MLO + WPA3-Enterprise Transition Mode, while iphone17 with apple wifi chip solution do not add such limitation
Also test other android devices and not found this issue
