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!
