I recently purchased an 1142 N AP for testing on our network. It is an AIR-LAP1142N-A-K9 and our controllers are running version 18.104.22.168. I was trying to set up the scope in our DHCP server for option 43, but I do not see this model. We are running microsoft DHCP on a 2003 server. Any suggestions?
Thanks for the information. I had been doing some research after I posted and came to the same conclusion. I will inevitably need to upgrade my controllers. As far as I understand the upgrade is seemless and will not require any downtime to our wireless infrastructure. Is this what you observed when you upgraded your controllers?
No in fact you will have some downtime. Remember, your APs are on 4.x code today. When you upgrade to 5.x the APs will need to take the NEW code and reboot. So the APs will be offline for a few minutes.
If you have a backup controller, perhaps you can fail all the APs to the backup 4.x controller. Upgrade the controller and move a few APs over at a time to the new controller so its not a all down situation.
Also if you upgrade from 4.x to 5.x, you may want to consider a WCS upgrade as well.
If you are using AP groups under 4.x and move to 5.x i (HEARD)you may need to reconfigure the groups.

1. Upgrade the WLC firmware. As what's posted by others, particularly George's comment, it is noteworthy to also upgrade the bootstrap. Unfortunately, the upgrading the bootstrap isn't straightforward and you need to upgrade everyone of them.
2. You can also wait for the Autonomous IOS version to be released. I guess this option is moot since you already have a WLC. But if this is just a one-and-only model and no further model is needed, then I guess this is the "lesser of two evil".
