I have two standalone 521AP and a 526 controller. I would like to change my standalone 521AP to controller mode. How do I get the the controller mode IOS? I have a CCO account but that won't let me download the software. Do I need to buy controller mode IOS again?
You have three choices you can try.
1. Contact your the vendor and ask if they can download the softwares for you; or
2. Contact the vendor and ask if they can provide you with a valid Service Contract so you will be able to download softwares ONLY (don't tell them about opening TAC/SRs or they'll refuse).
3. If #1, #2 fail, contact Cisco Service Centre and give them your CCO login and the S/N of your AP and controller and ask if they can provide you with a valid Service Contract.
I am in the same predicament as you so I did #3 option and now I can download softwares create SRs and TACs for RMA.
Hope they work.
NOTE: I hope you didn't buy your gear from [email protected] because the options will not work.
