Hi,

To make sure the WR902AC itself is okay I suggest you connect it to another network first. If no other wireless network is readily available, then use the Hotspot feature of a smartphone.

Don't bother with all the Quick Setup stuff. Go straight to either the "Wireless 2.4GHz" or "Wireless 5GHz" menu, in the "Client Setting" section click the [Scan] button, pick the network of your choice, enter the correct password in the "Wireless Password" field and then click the [Save] button.

In case the WR902AC connects fine to another wireless network, then it must be something about the Unifi network that the WR902AC doesn't like.
 

thanks for the tip, i packed it up and figured it was something relating to my home network. I will try again at the hotel. I got my clients set up by connecting the TPLINK to an ethernet port. I was hoping there would be some wifi logs to at least show if I had successfully connected to the my home WAP, and if not, why it was failing (bad password, etc). I never saw a connection on the unifi side, nothing in the security logs, etc. but the TPLINK was requesting DHCP, so it sort of implies it thinks it was connected. I'm sure it's something stupid, hopefully I have better luck at the hotel.
