I have lots of R600 v3 and a few v4. They runs well till now for me. I plan to purchase more v4 in the future.

Hi RS, where is the Exchange server? Is it behind TL-ER5120 LAN port? If it is, I think you should do port forwarding via virtual server for it.

If your PC IP acquirement type is dynamic IP, what the IP your PC get? And what's its default gateway? I think the gateway is router's Lan IP and you could use this IP to login.

router-----AP)))(((client, right? In fact they work in the same way wirelessly and wirely. The router will both do load balance.
