Apple Device Roaming

[jeremy_west_564]

I am having a problem with frequent disconnects on apple devices when signal strength is great. In looking into this further, I noticed that the apple devices in question are roaming at an alarming rate. This is happening across iPad, iPod, and MacBook platforms. For example, I looked at an apartment with an iPod touch that was roaming every 30 seconds or so. There is a Win7 laptop in the same apartment that has not roamed one time. I have about 40 Apple devices on the network and similar behavior is happening on 70% of them. I have about 40 other devices on the network and this is not happening with any of them that I have looked at so far. What is more, the Apple devices are roaming out from a nearby AP to an AP several hundred feet away with a few buildings between them. The user is not leaving the apartment but the device is roaming to APs throughout the campus, even APs it either should not see at all, or just barely.

Any ideas? Has anyone seen anything like this before?

I wrote this script to help me search for odd things in my ruckus logs:

Using this, I can see that the apple-branded device on my network that roamed the most yesterday had a mac address of 8c:58:77:19:4c:c9 and it roamed 192 times that day.
(it can take a long time to run)

I hope that helps someone.

Nice! Thanks for sharing!

This is a great conversation that's separate from the main topic, so I created a new topic to continue the discussion. Please reference the new topic here: Ruckus Log Search Script

Here's another script. (or set of scripts?)
https://github.com/bot779/ruckusconf

"ruckusconf" will automate an ssh login and download of configs from a controller, or get a supportfile from an AP, or from a group of APs.

"buildclientos" will build a database of wifi client mac addresses and the operating systems running on those clients.

I hope to update the zdroamers script (soon-ish?) so it can use this information to display operating systems of the clients that are roaming the most.
This won't tell me if it's "macbook air" machines that roam the most, but at least I'll be able to distinguish between ios devices and laptops.

The zdroamers script is now updated to display the operating systems running on clients that roam frequently.
