Hi @Palmhead,

Question #1:

I don't think a pure AP Mesh solution is advisable (or even possible) based on the mesh guidelines:

• Minimize the number of APs connected to the same upstream link "Uplink AP"
• Ensure that wireless clients are connected to the root AP or 1-hop AP as much as possible

Question #2:

Not sure what you mean by wired mesh.  If you're asking if you can use the wired network port on a meshed client AP to extend the network to another wired client, I think that's possible.

Question #3:

A full wireless soluton would require using EAP211 Bridge to extend the network to various points and then use the AP mesh expand coverage from there.  One EAP211 "Main" unit can have up to four remote "Clients" within 1km (70°) line of sight.  The topology would look something like this...

(EAP211 Main)>>Wireless Bridge>>(4xEAP211 Client)-Wired-(EAP625)>>Mesh>>(EAP625)

Note that the first two points in Question #1 would still apply to the "Mesh" at each bridged client so to improve performace you would need to decrease the number of EAP265s meshed together by adding more sets of EAP211 (Main/Clients).  If you have no budget, then start with 2 EAP211 Mains and 8 EAP211 Clients to bridge to each block and mesh the 625s together on each block.  You can increase the backhaul bandwidth and latency by adding more EAP211 Mains (decrease the client to main ratio) and/or eliminating the EAP625 mesh, by adding additonal EAP211 Mains/Clients.  Basically, reduce wireless hops and use wired links for the backhaul segments where possible.
