Ist beim Iphone evtl die funktion zum Wechseln der MAC Adresse angestellt?
Das würde dieses Verhalten erklären.
Evtl. mal mit ausgeschaltenem “Private Wi-Fi Adress” versuchen.

Open the Settings app and tap on Wi-Fi.
Now tap the i button from the right side of the Wi-Fi network for which you want to use your real MAC address.
Find the Private Wi-Fi Address switch and turn it off to disable MAC address spoofing on your iPhone. Note that, when the switch is on, under it, you can see the spoofed Wi-Fi Address.
When you disable the MAC address randomization feature on an iPhone, for the Wi-Fi to which you’re currently connected, iOS notifies you that “Turning off private address will temporarily interrupt your Wi-Fi connection.” Tap Continue to apply the change.
When the Private Wi-Fi Address switch is off, the Wi-Fi Address underneath it shows you your real MAC address instead of a spoofed one.
Also, on the Wi-Fi screen, if you disabled the MAC address spoofing for the network to which you’re connected, iOS will show a “Privacy Warning” message under it. The only way to make it go away is to enable MAC randomization again.
