Double entry in the device list

Michael_c

Hi,
Strangely enough, since a few days, my iPhone Xs Max appear twice in my device list with 2 different IP addresses and two different MAc addres....I deleted both, but they came back. They are never "together" on the network...

Any idea why?

Michael, 
Do you have two different SSIDs, one for 2.4WIFI and one for 5ghz WIFI? 
I suspect that the iPhone has a different mac for each network 2.4 and 5ghz. The iPhone uses mac randomization for an extra layer of security so each different network gets a different mac address.

Hi David,

thanks for your answer. I don't think I have two different SSID for the  2.4 and 5 Wifi (but I will check). But as I installed the Beta Version of IOS 14, I suspect that they have introduced this as a security layer as you mentioned...

Cheers

@Michael_c you can disable this random address in iOS by clicking on the the i next to the wifi name and there is an option to disable the random address for that network.
