We will replace the certificate of the radius server for wireless LAN today.
After the replacement, when you connect to SSID "JAIST" or "eduroam", you will be shown a confirmation screen that says "Continue connecting?"
Click "Connect" to connect to the wireless LAN.
We have confirmed that some devices cannot connect even if you click "Connect".
In this case, please delete the SSID and try connecting to the wireless LAN again.
