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.
