Even though the registration procedure for the on-campus Wi-Fi “MUSIC Network” has been completed, if you cannot connect to the Internet (such as an “!” appearing on the Wi-Fi icon, or pages failing to open), the primary cause is that “the applied MAC address” does not match “the actual MAC address of the computer.”
If there is even a single character error in the input, the on-campus system will automatically block communication. Before coming to the Help Desk service window, please first verify and re-apply according to the following three procedures (you can resolve this yourself in about 3 minutes).。
Procedure 1: Confirmation of Application Details
Open the automatic reply email that arrived immediately after applying for network use, and check the value of the MAC address you entered.
- Target Email:『フォームにご記入いただきありがとうございます: 無線LAN（MUSICネットワーク）利用申請フォーム(学生用)』
Procedure 2: Confirmation of the Correct MAC Address and “Comparison”
Refer to the link below to check the actual MAC address of your computer. Be sure to compare and verify whether it “completely matches” the value stated in the email from Step 1. 👉 Click here for how to check your MAC address
🚨 【Most Important】To Those Using a MacBook (Apple Product)
If the device’s Private Address feature is enabled (Fixed / Rotating), the correct MAC address will not be displayed, resulting in a mismatch with your application details. Please make sure to turn “Off” the Private Address before checking the address.
💡 Points Prone to Mistakes—Check Before Copying! A MAC address consists only of “numbers 0–9” and “letters A–F.” You will not be able to connect if even one character is incorrect.
- Beware of Misreading: “8 and B” and “0 (Zero) and D” are very easily confused, so please double-check them carefully.
- Is it “for Wi-Fi”?: If multiple addresses are displayed, please choose the address labeled as “Low Power Wi-Fi,” “Wireless LAN,” or “Wi-Fi.” Addresses listed as “Ethernet” or “Bluetooth” will not allow connection even if registered.
Procedure 3: Correction of Application Details (Re-application)
If you find that the values were different (there was an input error) as a result of your check, please submit the correct address again using the form below.
👉 MUSIC Network Use Application Form
*When you re-apply, only the latest application details will become valid (overwritten). *It takes up to 2–3 business days (usually 1 business day) for the re-application to be reflected in the system and for the connection to become available.
💡 If the Issue Is Still Not Resolved / If You Are in a Hurry
- Consulting at the Service Window: If you still cannot connect after trying the steps above, please bring your laptop computer itself to the “MUSIC Help Desk” at your respective campus.
- When You Need to Use the Internet Immediately (In case of emergency): If you are in a hurry because a class is about to start, etc., you can connect to the on-campus network “MU-NET” as a temporary workaround.
