Introduction
On the latest operating systems for Mac and iPad (such as macOS Sequoia 15 / iPadOS 14 or later), a feature that automatically creates and changes a temporary MAC address (Private Wi-Fi Address) is enabled by default for security protection.
Due to this feature, even for devices that have already completed the user registration for the “MUSIC Network,” the automatic changes to the MAC address are causing technical issues where devices suddenly lose their internet connection.
If you experience issues such as “Suddenly unable to connect to the campus wireless LAN (MUSIC Network) despite having completed registration” or “The connection drops frequently,” please follow the steps below to set the Private Wi-Fi Address to “Off.”
