WLC5508 wifi dropping

We gave a problem with ipad/imacs droping wifi every day. DHCP is set on the controller. Firmware version is 7.4.110.0. Most AP are AIR-CAP36021

 

After drop, I have to add security key manually. I saw people having problem if external DHCP was used. Lease time is set to 43200. 

 

Where I can start troubleshoot the issue?

Things to make sure you have

Things to make sure you have:

  1. Only only use either WPA/TKIP or WPA2/AES.  Don't use both or a mix
  2. Upgrade to v7.4.121.0
  3. Make sure you have uploaded FUS 1.9.0.0
  4. Disable client load balancing on the WLAN if enabled

The settings we have are: 

The settings we have are:

 

[WPA2][Auth(PSK)]

 

Still have some IPADs loosing connection I mean I have to put password again. The problem is is not happening to all of them. They are on the os v 7 - all same version. Where can I check the logs in the controller?

 

Thank You

If you are having to

If you are having to reconfigure the iPad, the WLC logs are not going to help you as that is an issue with the iPad not the WLC.

 

ehat you can try on the iPads is forget the network, then disable wireless for 1o seconds. Then tenable the wireless and put the psk in

Thank You Steve, I have

Thank You Steve,

 

I have already tried a couple workarounds and none of them works. If I use only one ipad that would not be a problem but we use around 400 ipads so ..... retyping the password every a couple days is really pain .....

 

Most of them are connected for a couple of days, and then dropped the wifi. So I have to take the ipad and retype ssid password.
