We’ve changed our istwlan certificate to a new issuer as the previous one as expires 01/12/2021. This may prompt your device to request that you trust the new certificate to continue to use the istwlan wifi connection.
The new certificate to expect is: ‘wlan.ist.ac.at’; issuer ‘GEANT OV RSA CA 4’
If you’re unable to reconnect to istwlan you may need to manually forget the network and reconnect. Instructions on how to forget a network per operating system can be found here. As always please feel free to visit us in the IT Support office if you require assistance.
