The Cisco 37021 AP with a Standalone Image

The following steps allow you reuse a Cisco AP; in my case the AIR-CAP3702I-A-K9 802.11AC.

Resetting Configuration

Hold down the MODE button while applying power. Release after you see the message 

button is pressed, wait for button to be released...

Then run 

dir flash:
delete flash:private-multiple-fs
reset

Log in and clear the rest of the config 

Username: Cisco
Password Cisco
enable
clear capwap private-config
clear lwapp private-config
reload

Loading Standalone Software

Find the recommended release for your AP. This page will also include checksums to make sure you have the correct image. After applying power, tap ESC repeatedly until you see the boot loader prompt (ap:)

Load the image from your TFTP server 

set IP_ADDR 192.168.0.99
set NETMASK 255.255.255.0
set DEFAULT_ROUTER 192.168.0.1
ether_init
tftp_init
tar -xtract tftp://192.168.0.11/ap3g2-k9w7-tar.153-3.JD.tar flash:

After 15 minutes the AP should complete. Take note of the image name and try booting from the new image 

BOOT=flash:/ap3g2-k9w7-mx.153-3.JD/ap3g2-k9w7-mx.153-3.JD
boot

Final Configuration

Now that we have a standalone image running. Now we can add configuration 

config t
