Iphone and IPAD intermitently disconnects with wireless

Hi all friend and expert !
 
I have some confused issues:
I used IAP 325 and controller 7205
All of my devices are running well, except iphone/ipad/IOS (apple devices), I met some following phenomena:
After connected, it already got IP from DHCP server, but it disconnected and then reconnected.
All of my laptop window, android still run well
 
Please give me some ideas to troubleshooting this issue
 
Thank you so much

What kind of encryption do you have on that WLAN?

 

Please make sure you don't have 802.11r, k or v enabled on that SSID.

Re: Iphone and IPAD intermitently disconnects with wireless

Dear Colin,

 

For encryption im using:

Mix mode : WPA-AES,WPA-TKIP,WPA2-AWS

For authentication im using:802.1X via Cisco ACS (EAP)

Already disable : 802.11r,k and v

 

Thank you so much

Re: Iphone and IPAD intermitently disconnects with wireless

You should not be using WPA-AES or WPA-TKIP.  WPA-AES is insecure and WPA-TKIP is also insecure, but forces the client association rate to be 54 megs or less.  In addition, some clients have problems with a mixed-encryption SSID.  You should standardize on WPA2-AES which provides the best speed and security.  To find out what clients could be using WPA-AES or WPA-TKIP, you should use the command:

 

show dot1x supplicant-info list-all 

 That will tell you how many of your clients are using WPA-AES or WPA-TKIP that you need to reconfigure to match WPA2-AES.

Re: Iphone and IPAD intermitently disconnects with wireless

Dear Colin, and all

 

My topology

Master

Local

master and local different geography.

 

I have just deloyed in a new building, all the users here will be connected in controller local.

According to my understandings, user connecting into WLAN will be authenticated on Local controller.

But when I check log access on Radius sever (ACS), it is always authenticated by controller master.

I didn’t find any user authenticated on Local at all. However, I still see user list of new buildings connecting into WLAN on local controller.

 

Please give me some advices

 

Thank you so much
