IEEE 802.11ai is a Wireless LAN standard from IEEE that since June 2017[1] provides fast initial link setup (FILS) methods that enable a wireless LAN client to achieve a secure link setup within 100ms, designed to improve dense environments.[1] FILS provides fast roaming without 802.11r.[2]

The Intel wireless daemon IWD that is slated to replace wpa_supplicant in Linux added support for FILS in May 2019.[3]

A denial-of-service attack has been reported for 802.11ai.[4]
