Passwords are a major cause for user disruption today. Itís not the wi-fi, but the password resets and disconnected devices that are creating all the furore. If every student uses anywhere up to seven devices, and they get disconnected from the network, each device will try to reconnect with the network leading to up to 210,000 authentication requests per day per student. Certificate-based wi-fi is the answer to this. Here, connectivity continues to function in spite of password changes. So, a device registered one time continues to function throughout the year without disruption!
