At work we happened to have a Cisco 1130AG left over. I decided to use it in our lab setup so I went on to configure it. After about 30 minutes troubleshooting, getting hang of a serial cable and googling for how to actually connect and configure it I realized that it was in what Cisco calls “lightweight” mode. This means that the AP has a minimal operatingsystem and gets all its configuration from a Cisco controller. Well, we only have one AP so I didn’t see the need to install all that into our infrastructure. So how do you get your lightweight AP to a fullblown one so that you can configure it?
You’ll need a tftp-server with an ip between 10.0.0.2 – 10.0.0.30 (this is most likely hardcoded into the rom of the AP).
You’ll need to obtain the file from Cisco. This took the longest since their form is “really well constructed”.
Rename the file, place it in the root of the tftp-server and reset your AP by unplugging the power, pressing the mode-button and plug it back in. Hold the mode-button for 20 seconds (until the R-light turns red).
Verify in the tfpt-log that the AP has gotten the image, it’ll then reboot and you can configure it normally. See link to the manual at the bottom of this post.
Oh, and don’t miss the small but important part of allowing TFTP through the firewall on your workstation… I won’t say that I missed it, but it’s a crucial part of making it work.
Obtaining your iOS-image:
(You’ll need to register first, that takes a while considering the very nice form Cisco has made… Make sure to repeatedly fill in your password, don’t use international characters in any field, and be quick so you can submit that form before your session expires. Maybe some of all that R&D budget should go to the web-guys?)
