Oc200 version below:

I did just discover that there is newer firmware for the Oc200 and EAP211 on tplinks website. Perhaps I'll try to manually update them myself. But I'm still hoping someone will answer my previous questions. Release notes for the eap211 firmware pasted below:

 Hi @Vincent-TP 

This is wrong and misleading on TPlink's part. They need to correct this. 

I just bought an EAP215 V2 bridge kit to find out the answer for myself. They are labeled with stickers "Main AP" and "Client AP".

I had to wire the Main AP to the network in order to find it and adopt it. Even after being adopted it will not connect wirelessly.

The Client AP was able to be adopted wirelessly. But requires that at least one Main AP bridge is already adopted. The EAP215 Client AP was able to be adopted by the EAP211 Main AP.

I updated the OC200 to 5.15.8.12 and the EAP211 V2 and EAP215 V2 to 1.0.2. Still no way to turn a Main AP into a client. What am I supposed to do with this Main AP I bought? I just wanted to buy 2 more clients. I'm replacing old Ubiquiti Airgrids and I am starting to regret that decision.

Thank you for trying to help. Below is the UI I am looking at. I cannot find any such setting anywhere.
