So a buddy of mine wants to do mesh networking for his house. It's a two story 2500 square foot house and has a decently big backyard that he wants to have range there too. We're looking at the Google mesh thingy for his house since he has the Netgear N900 that does a decent job but he needs more range. The office is pretty much on one side so obviously the range needs to hit a good distance to get outside and to the upstairs. It's a solid house for sure. Any suggestions? Powerline isn't an option and the entire house is more of a "smart house" of wifi.
