Thanks for letting me know. I've emailed you directly with some firmware files, we'll want to update before the AP will work with the HiveManager. This guide will walk you through how to update the AP via their Web UI: https://thehivecommunity.aerohive.com/s/article/Upgrading-AP-firmware-via-web-UI
To push a new SSID to an AP, you'd want to go to Monitor> Select the check box next to the AP you want to update> Update Devices> Choose Complete update. Is that what you are looking for?
