4 way handshake timeout

ittechk4u1
Level 4
Level 4

Hello experts,

I am getting the eeor on a WLAN

"Client Deauthenticated: MACAddress:xxxxxxxxxxx Base Radio MAC:yyyyyyyyyyyyyy Slot: 0 User Name: unknown Ip Address: unknown Reason:Authentication rejected because of challenge failure ReasonCode: 15"

 

I read somewhere that its a issue of 4-way handshake timeout. This means that during the initial phase of authentication the wireless client didn't respond or didn't respond within the time frame.

 

How can i  increase the 4 way Handshake timeout on WLC or in WLAN?

 

Thanks
