Cisco air (wireless) questions

Hi Experts,

I have 3 Cisco AIR-AP1242AG-A-K9 devices and one Cisco Wireless LAN Controller (AIR-WLC2006-K9). do you think these 3 devices would work with this cisco controller model perfectly?

If they do, how do I set them up? I've setup cisco router/switches but never done with wireless so if you can provide any documents how to set these up I'd really appreciate. Thanks.

No, the AP's are currently autonomous and they need to be "upgraded" to Lightweight to work with the controller.
Cisco has a utility to upgrade the AP's. You have to have the lightweight IOS image as well as the the utility.

I think you'd have to convert them to lightweight access points with a different image.
By default AIR-AP* devices are configured as autonomous access points that don't need a controller, but can be converted to lightweight. AIR-LAP* devices are 'lightweight' (requiring a controller) from the factory, and cannot be converted to stand-alone (autonomous) access points.

That controller should handle up to 6 of those (or any other 1000 series) AIR access points.

Oh, and if I recall correctly, that 'upgrade tool' doesn't work when run on vista/7.

I found a Cisco video that walks you through converting autonomous to lightweight and vice-versa.

Hi There,

I was able to upgrade this device to the image you mentioned above. After the upgrade, the device is booted fine but the 3 LED lights (1 big & 2 small) are kept flashing, before upgraded they weren't like that. Are these normal?

There are also few logs which I've found from the device:

What steps do I need to do next? Are these logs are normal?

Is the 2006 controller setup and configured?
Do you have DHCP/DNS on your network? The AP should get an IP address from DHCP, with the domain name and DNS server IP.
The DNS server should have an A record for CISCO-LWAPP-CONTROLLER with the IP address of the WLC2006 controller

Hi there,

Sorry for late reply. The controller has not setup yet. I've been busy lately. I'm going to close this one and hopefully open a new one when the controller is ready. Thanks.
