If you’ve never used a Cisco Access point ( Aironet ) by default out of the box or after a factory reset the dot11rad 0 interface will be set to shutdown and will no broadcast any of your SSID’s

Also by default only webpage administration is available, you can enable SSH through the website Administration

Enabled through SSH :  

ap(config)#interf dot11rad 0

ap(config)#no shutdown

Depending if you have 1 or 2 SSID you will need to enable Guest mode or MutliGuest Mode
