Thank you for you reply. I have tried a few different data rate
combinations including 12 mandatory and lower ones disabled. It didn't
seem to help.

How are your data rates configured? I seem to recall something about Apple
devices that used to be picky about it. We don't have Cisco, but we have 12 as
Mandatory and everything lower disabled for NG.

Subject: [WIRELESS-LAN] Older Apple devices and issues with 802.11N(2.4Ghz)
I'm having an issue with some Apple devices and was wondering if anybody has
experienced similar or if you have a similar environment and all is working
well...
My environment is 5508 controllers (8.0.140.17) with 1600 series and 1702i APs.
We have 1242 AP so cannot upgrade past 8.0..
I am having an issue with what seems to be only older Apple devices on
N(2.4Ghz). The devices authenticate/DHCP just fine but are very slow and only
seem to work for a few minutes until you have to restart the wireless card.
Loading a video is impossible...pings timeout and have very high latency. Most
the time the client cannot even ping the gateway. I have been able to recreate
this with iPad, 3rd and 4th Generations, an older Macbook Pro and an iPhone 5c
while using 1602i, 1602e, and 1702i APs. I haven't confirmed any other brands
having this problem.
The devices mentioned above work great if I disable the N data rates on the AP
radio. I had two users that were crippled with this issue, so I disabled the N
data rates for one building over the weekend. The users said their devices
worked great over the weekend. They also work well on the 5Ghz band but we
have areas that rely on the 2.4Ghz coverage. If this issue is not resolved
before school starts, then I'm afraid will have to disable N data rates
globally for the 2.4Ghz band.
Appreciate any feedback!
