It is better, but notice this list is only on specific devices. For example, I have an iPad 4th gen that works great and runs iOS 10 fine, but doesn’t get this roaming improvement. I also know of a number of iPhone 5 users.
Since users don’t often know what they have, we often ask them to turn WiFi off and back on and see if it improves the signal or performance. That is interesting that the AirPort utility has a WiFi scanner; having an iPhone myself that can come in handy.

Apple's phones seem to be the smartest about this, in my experience. They even released a document detailing their roaming logic: https://support.apple.com/en-us/HT203068 On Thu, May 11, 2017 at 1:39 PM Thomas Carter <tcar...@austincollege.edu<mailto:tcar...@austincollege.edu>> wrote: And mobile devices, especially Apple’s, tend to be very sticky clients and stay connected to an AP as long as they can see it. We don’t have Cisco, but I’m sure there are settings to help encourage roaming of clients.

If you don’t have it, I’d look at getting it. Your life will be far better. That said, a few comments: • SSIDs – have you confirmed that they are all setup identically? Lots of knobs can be turned for each SSID that can impact the client • Do you have client band steering or load balancing enabled? In general, while clients have gotten better about honoring the trickery, many still don’t. In most cases, clients (especially Apple’s) do a great job now in picking the best SSID, so the need for controller tricks is diminished. In other words, disable these if you have them enabled and see if client happiness improves. • Code – Get off of 8.0 (or at least get to 8.0.140.0). Preferably, get to 8.2MR5 where you will benefit from a lot of improvements, not only in client-AP compatibility, but additional features that will make your life a lot easier.

Scenario 2 Physical area: In-doors in Dorms/reshall Infrastructure : Cisco 702W(80%) AND 3702I(20%) with WISM 8.0.133 Customer report: I get slow internet Observation: Customer device not connected to the strongest/closest AP • They might have been until an event happened (rogue AP or channel change) , but they don’t go back Client devices – Apple/Samsung/ laptops/tablets/smartphones Troubleshooting – it is not intuitive to find root cause via status codes Additional notes: I am using RF profiles controller power and data rates in an attempt to force them to connect to the strongest and closest AP Recommendations -?
