In order to use fast roaming with IAPP, you need to assign an individual IAPP passphrase in the WLAN encryption settings for each interface. This is used to encrypt the pairwise master keys (PMKs). APs that share a matching IAPP passphrase (PMK-IAPP secret) are able to exchange PMKs between themselves and ensure uninterrupted connections.
To enter the IAPP passphrase in LANconfig, navigate to .
Important: Please note the use of IEEE 802.11r requires WPA2/3 key management in the encryption settings to be set to "Fast roaming".
