* 802.11r mixed mode support – Untill this code(8.0), if you enable 802.11r fast secure roaming, only that feature supported clients (eg Apple iDevices) can join this SSID, all non-802.11r clients cannot join. But in 8.0 both types of clients able to join, but only 802.11r clients get fast roaming.

如果啟用802.11r快速安全漫遊，只有該功能支援的客戶端（例如Apple iDevices，iPhone or iPad (running iOS6 or above).）可以加入此SSID，所有非802.11r客戶端都無法加入。 但在8.0中，兩種型別的客戶端都能夠加入，但只有802.11r客戶端可以快速漫遊。

1. 802.11r mixed mode support in 7.6 & 8.0 (both codes)
2. Still few supplicants  (Mac OSX, Netgear,ect) does not like mixed mode WLAN, so they may have trouble associate if you enable FT
