A Study Of Mac Address Randomization In Mobile Dev Pdf Pdf Wi Fi Learn how apple’s newest beta version of ios 14 has the possibility to change the way people connect and stay connected to wi fi networks with mac randomization. This document lists various network environments and a range of network services that may be affected by such randomization. this document then examines settings where the user experience may be affected by in network state disruption.
How Mac Address Randomization Can Affect The Wi Fi Experience While mac randomization benefits users in public spaces, it can disrupt the operation of enterprise wi fi environments that rely on stable device identities. the consequences manifest in several critical areas of it infrastructure:. In environments where mac randomization could impact network performance, configuring wpa2 (aes only) or wpa3 password protection on hotspot ssids ensures that devices use a fixed private address. this approach prevents mac address rotation, providing a more stable and consistent connection experience. In response to these privacy vulnerabilities, most oss—including android, ios, and windows—began to implement their own variant of mac address randomization while probing the wi fi network. this probe mode guarantees anonymity until the client gets associated with an ap. Mac randomization can also cause connectivity issues on public wifi. having to repeatedly login, being unable to reconnect to previous networks, and losing network services that rely on static mac addresses are all potential issues that guests might run into.

Mac randomization can also cause connectivity issues on public wifi. having to repeatedly login, being unable to reconnect to previous networks, and losing network services that rely on static mac addresses are all potential issues that guests might run into. To prevent this kind of tracking, apple’s latest changes causes their devices to have a rotating mac address. with these changes, devices will rotate their mac addresses every two weeks. while this update protects user anonymity, it poses challenges for wi fi service providers who rely on stable mac addresses for network management. Finally, we provide a list of attacks that can be used to track wi fi devices despite the use of mac address randomization, including attacks based on the content and the timing of wi fi frames. What if devices randomize only within assigned oui? i.e., first three octets “fixed”?. For long stay guests, ios 18’s mac address randomization will cause them to see the login page again every two weeks, even if they’ve previously connected. as the network no longer recognizes their device, this disrupts what should be a seamless reconnection process.
