you can check this link from Cisco to check which software could support your Access Point http://www.cisco.com/c/en/us/td/docs/wireless/controller/release/notes/crn80mr2.html

So i open a ticket with Cisco TAC and let me tell you i always enjoy working with such an Expert like Cisco TAC

I show in earlier blog how to install WLC

First i need to download the Image from Cisco Web Site https://software.cisco.com/download/navigator.html?i=!mmd

and Navigate to your WLC Model, we have 5508 but you should have a valid service contract 1i Choose the WLC Software

and i Choose the Firmware that Cisco Suggested Depend on Software quality, Stability and Longevity. i think this a new Cisco thing since i didn’t see this option last year were they suggest which one is better3

I Download it to my Laptop and Save it to a folder and used a TFTPD32 Open SOurce software which can be downloaded from http://tftpd32.jounin.net/

then in the WLC i go to Command Tab and choose Download
File Type: Code
Transfer Mode: TFTP
Server Detail

File Path: /
File Name: My Software Name in my Case (AIR-CT5500-K9-8-0-121-0.aes)
Then Press Download

you can see the under the TFTP transfer procces start in the TFTD32 Software and also in the Command Download Page in WLC

it took almost over 40 minute then go to Commands Tab then CHoose Config Boot You will see that the Primary Image Change from 7.4.110.0 to 8.0.121.0

    Hello, I’ve specified two new AP 2700 series to my company but I didn’t pay attention on the firmware version so I just found out that my WLC 5508 doesn’t have the firmware version it must have, at least 7.6.x. Could you help me? Do you have a copy of the last firmware version(AIR-CT5500-K9-8-0-121-0.aes) to share with me?
    Since right now thank you very much!

  2. Good afternoon. Thank you for your attention.. I should expect it. Actually we’re in process to buy the smartcare/smartnet and reactivate our service contract..
    Sooner or later we’ll sort it out.. so thanks again.
