YNU students, faculty and staff members having a YNU User Account can use the YNU-WiFi.

For faculty and staff, please use the wireless LAN "YNU-STAFF-ONLY" exclusively for faculty and staff.

How to use the YNU-WiFi service (ITSC Wireless LAN)

  1. Change the network setting of your PC/mobile device to "Auto-Configuration".
  2. Select ITSC Wireless LAN station.
  3. Enter your YNU Login ID and password.

Can't Connect to the YNU Wi-Fi?

If you change your password, clear your network settings.
If your device remembers your old password, the connection may fail because the device may attempt to connect to Wi-Fi with the old password even after you update the password.

In Windows, open [ Network and Internet settings ] > [ Wi-Fi ] > [ Manage known networks ], then delete the YNU Wi-Fi network. When you next attempt to connect to the YNU Wi-Fi network, you will be prompted to enter your user name and password.
