Roaming seems broken since 4.1 update for Apple devices

  • 1.  Roaming seems broken since 4.1 update for Apple devices

    Posted Aug 07, 2014 11:00 AM

    When I was running my five IAPs on 4.0.0.6, roaming was working great and I got lots of compliments. 

     

    Ever since upgrading to 4.1.0.0 and now 4.1.0.1, people have been complaining wifi dropouts on iMac/Macbook and roaming just doesn't work on iPhones (all iPhone 4s and above). When the iPhone tries to roam, it connects but the user has no internet at all. This seems to be a problem for multiple users including my boss, so not good.

     

    802.11k was turned on by default it seems after the 4.1.0.0 upgrade, 802.11r was not so I enabled that thinking it would help. Unfortunately it seems to have had zero effect on roaming abilities. 

     

    Is anyone else noticing this since the upgrade? I'm actually thinking of downgrading the devices because I had way fewer problems and complaints.

    How is your settings on Client Match?

    I havent messed with the defaults at all, but here they are:

     

    Client match: Enabled

    calc interval: 30 seconds

    neighbor matching: 75%

    threshold: 2

     

    Thanks.

    OKC was enabled by default in 4.0.0.x but is now disabled in 4.1.  I have not checked, though, to see what happens to that setting on an SSID to see if once enabled it stays enabled through the upgrade.    Check it under the security settings on the SSID.   This only applies if you are doing WPA2-Enterprise.  I don't think the Macs support 802.11r yet.

     

    Also, is this a single cluster or are the users roaming from one cluster to another?

    Marcus,

     

    This is a single cluster of five IAPs on one floor. Thanks for the reply.

    OKC was turned on before and verified it is still turned on after the upgrade. I did turn off 802.11k/r on our SSID used for mobile devices, still contemplating turning it off on the user laptops SSID.

    Did you have any luck disabling 802.11r & k? with Client Match enabled?

    Hi, 

     

    I have had success with disabling 802.11r, 802.11k, and client match enabled, somehow iDevices have trouble roaming with the settings on.

    Ive seen that SK too. All devices on the network are compatible with it, so not sure why there are more problems with it enabled.

     

    Thanks.
