where do I find my Mac address on my phone

To find your iPhone MAC address -> go to Settings -> General -> About -> the Wi-Fi address.

1. Open the Settings app.
2. Select General.
3. Select About.
4. Scroll down and note Wi-Fi Address.
5. The Wi-Fi address is your Mac address.

Already answered that question above. Here it is again:

This happens because the iPhone disguises itself. If you don't want it to do this.

Tap Settings

Tap Wi-Fi

Tap on the blue "i" circle next to the name of the Wi-Fi network

Scroll down and turn off Private Wi-Fi Address

Your iPhone Wi-Fi connection is now not as secure as before....and you may see a Privacy Warning.....but it is your call.

I found this information, but my router registers a different number. Why does that happen?
