Our house is a 2 story brick place, 170m2 each story. The current wifi strength doesn't cut it, so the upstairs WRT54gs is boosted by an Ethernet Over Power wifi box downstairs. Running cat5/6 cable would be difficult, but not impossible given the construction of our house, so a wifi implementation is preferable.
After some considerable reading, I think I've narrowed my selection down to the mikrotik RB2011UiAS-2HND-IN or the ASUS RT-N66. I have no AC clients, and don't anticipate any for quite some time, so AC or dual band radios are not needed. Both routers have 600MHz CPUs and should have enough RAM/CPU power to run my OpenVPN network and route traffic around the house. Basicaly would be looking at a router for the next say 5 years, so it doesn't have to be the be-all-end-all right now.
Pros: cheaper, prosumer-quality, well reviewed, 1mw wifi transmitter with supposedly very good coverage possibly avoiding the need for an additional AP, PoE (could be useful if I need to add a Ubiqiti AP)
Cons: supposedly steep learning curve with RouterOS, limited openVPN implementation (no UDP, no compression)
Pros: I'm very familiar with dd-wrt (and its decent openVPN implementation), well reviewed & supposedly good quality (for a consumer-level box).
Cons: Lower transmit power, no PoE, more expensive.
I've also considered an appliance running pfsense with separate dedicated wireless APs (like the ubiquitis), but even I reckon this is probably overkill for our current and anticipated needs.
So, in your esteemed opinions - the ASUS or the mikrotik, or any others not here mentioned?
