I am at my wits end. I have my NCA5123-NI access points, and one NCA5123-AC-HD, setup with a security profile to use 802.11r. According to Apple, all new iPads support this. I understand that the iPads themselves drop a connection a -70. I have setup my APs, to require a minimum -70 and to drop connections at -75. My Wi-Fi was never a problem w/laptops, but since adding iPads, it has been a nightmare. I have done testing, and my signal strength seems to be fine. The issue seems to be that as my users roam, they iPads are not smoothly transitioning APs. Sometimes, I have seen them completely lost connectivity, and even know they are right next to a strong AP, I have to toggle the Wi-Fi on the iPad to get it to transition. Other times, it seems to work fine transitioning as expected. I am starting to think that Zxyel is just not a good fit for use with the iPads. I have seen this article below and I am wondering if it isn't because with the the default Over-the-DS the the client is not able to always "communicate with the target AP through the current AP". I am thinking about switch over to Cisco devices, but up until now, have been happy with the ZyXel solution. Does anyone have any suggestions. Thanks.
For a client to move from its current AP to a target AP by using the FT (Fast Transition) protocol, the message exchanges are performed by using one of the following two methods:
• Over-the-Air FT Roaming
The client communicates directly with the target AP by using the IEEE 802.11 authentication with the FT authentication algorithm.
• Over-the-DS (Distribution System) FT Roaming (by default)
The client communicates with the target AP through the current AP.
The communication between the client and the target AP is carried in a FT action frame between the client and the current AP. Then it is sent through the Ethernet.
