Each wireless access point (WAP) must be configured with the according settings (see Table: Required wireless access point settings).
If your wireless access point does not support wireless session settings from the configured RADIUS server, change the default reAuthPeriod configuration setting to the required period before a fast reconnect should be attempted. One hour is the recommended period.
Configure the supplicant to request authentication details for every full authentication whenever possible. If this is not configured, each automatic full reconnection attempt (not fast reconnect) will cause a failed authentication.
