I've been playing with both the EAP211 and EAP215 kits for bridging - implementing a large-area camera system. 

These devices seem to have great bridge connectivity, and the controller is getting there (I come from the Unifi realm).

I'm curious - can I set up multiple units to connect to a single unit?  Think of it as multiple telephone poles sending back to a single hut.  Is there a limit to the number of extra connections?

I thought I saw somewhere in the controller software somewhere today that 1/5 connections were used (while trying to pair of EAPs).  But I did not find a "bridge" section that indicated I change those specific settings.

Would I have to do it by setting up on pair in the default way, then access the 3rd unit directly, and manually connect it to the hut EAP, then do the same for the 4th, 5th, etc?
