Cisco WAPS/ 2100 WLAN controller

We have a Wifi setup currently using 3 standalone Cisco AIR-AP1242AG devices.

We are experiences several issues with the setup and off the back of this want to incorporate a Cisco WLAN controller to manage them and also add a 4th AP to expand the range across the office.

I'm confused about which firmware needs to be applied to the AP's in order to link them to a controller. I've read they need to be configured in a specific way to achieve this setup?

Thanks

You need to install lightweight code on the APs in order to link them to a controller.

If you have a support contract for your APs you can download the lightweight recovery image from the Cisco website.

You can tell for sure which file is lightweight by checking the filename.  If it contains k9w8 in the name it's lightweight.

You should look for a file with rcvk9w8 in the filename.  That tells you the file is a recovery image for lightweight code.

ours are on k9w7

for some reason I'm having problems hitting the management port IP after the initial controller config so I can get into the GUI.

Yes, k9w7 is autonomous code.

Did you set a management VLAN ID?  If so, can you post the switch port config where the WLC connects?  If the WLC connects to an unmanaged switch you need to set the management VLAN ID to 0.
