WiFi Guard forgets or does not recognize my iPhone

WiFi Guard forgets or does not recognize my iPhone 20 January 2026, 08:39

WiFi Guard forgets or does not recognize my iPhone 16 Pro each time after computer reset. Any idea why this happens?

I have many devices connected to my network and everything works well: WiFi Guard correctly recognizes them all, except iPhones.
I am using DHCP and it is valid for all devices on the network. What could be the reason for such behaviour with iPhones?

Thx for reply

This behaviour is caused by the MAC address randomisation feature in modern iPhones. It is normal and expected in iOS devices unless you disable MAC randomisation for the network in question.

WiFi Guard identifies devices by their MAC address. By default, iOS assigns a random MAC address for increased privacy. When that MAC address changes, WiFi Guard detects the iPhone as a new or different device, which is why it appears as unknown again after a restart or rescan. DHCP itself is working correctly and is not the cause of the issue.

To ensure your iPhone is consistently recognised, please choose the "fixed" Private Wi-Fi Address option for your Wi-Fi network in your iPhone settings. This is a safe choice for a trusted home network that allows WiFi Guard to identify your iPhone reliably. You can find detailed instructions and additional information in our Knowledge Base.
