Running the 'latest' aruba instant and im finding most clients will not automatically join the AP while in power save, ie locked, when they come within range after being away for a few hours. The only way they will join is if they are unlocked.
This has also happened when ARM has shifted channels, even with the channel switch announcement count set at 3.
Clients in particualr are iphone6s and this affects both the 2.4 & 5 networks.
Thanks for any pointers.
I dont think i have twekaed any settings that would cause this although i'd appreicate it if anyone could tell me if is one/some that i should check.
