We have Cisco Wireless controller 2504 running with the firmware Software Version 184.108.40.206 and we often face issue with new Apple Iphone with IOS 7.0 face issue when they try to login to the wifi-ssid, its gets connected and disconnected. Following are the details..
LAN Controller: Cisco WLAN 2504
Acces-Points Model:- AIR-LAP1141N-E-K9
Software Version 220.127.116.11
Field Recovery Image Version 1.0.0
My question is we are using a trial license of 25 AP supported. We are facing lot of issue with the controller with the Apple Devices and the Wireless Speed is slow like maximum we are getting a speed of 45Mbps...... Is this normal?
I would like to upgrade the Cisco Wireless Lan controller to the recent one which will even support the model number Acces-Points Model:- AIR-LAP1141N-E-K9 as one of my friend advised we need to double check before uprating the firmware.
I would like to know is their any way to increase the speed and want advise regarding the firmware of the Cisco WLAN 2504 which will support the AP Acces-Points Model:- AIR-LAP1141N-E-K9
Why I am getting this message *dot1xMsgTask: May 16 22:00:17.494: %DOT1X-3-MAX_EAPOL_KEY_RETRANS: 1x_ptsm.c:444 Max EAPOL-key M5 retransmissions exceeded for client b8:76:3f:42:7b:b1
can you post your WLC configuration? the Speed depends of many factor as a goods RF desing or if your ap is N or not. are you try with no security on your WLAN?
I know about the upgrade path...
U never answered my question?

I was referring the document and found that Cisco firmware release recent one is also supported with AIR-LAP1141.. My question, if we purchase it will that affect our free license that can have 25 AP with the device. Please advise.....
I would recommend (if possible) disabling all the rates below 12Mbps. Set 12 and 24Mbps to Manditory and enable "Fast SSID Change" in the Controller tab General section.
You mention that you are "only" getting 45Mbps. If this is your actual throughput and it is not good enough then you should have bought the 1142. The fastest connected data rate for the 1141 (2.4Ghz only radio) is going to be 150Mbps and real TCP thoughput is always way slower then the connected data rate and will vary depending on your configuration and the type of traffic you are sending.
If you upgrade the code your trial license will not suddenly expire.
I hope this helps.
DOT1X-3-MAX_EAPOL_KEY_RETRANS: Max EAPOL-key M1retransmissions exceeded for client message is seen when during the 4 way handshake of the device and the WLC, the AP is unable to send the packet to the client.
You can try upgrading the controller on he client software. Try disabling the lower data rates.. Please check for interference and coverage holes..
