Recent Apple updates include important wireless performance improvements.
Having many wireless customers, Ruckus tries to provide news to be helpful.
Reports on Apple support describe important improvements in Yosemite 10.10.4
and iOS 8.4, which you should consider if running an earlier version.
If unable to upgrade, to workaround 802.11h issues, consider using only channels 36,40,44,48
in 5GHz indoors.
