D-Link's DIR-2660 and DAP-1820 offer a great way to start your mesh network. As with many mesh networks, this setup can be configured with a wired backhaul which would help some of the bottle neck issues I mentioned, but most people are resistant to running wires. So where this unit shines is in its scalability. You can start with just one extender or add several to cover even more area. Also a big benefit of this mesh system is having a few Ethernet ports on the router.
