I also keep things fairly simple. Despite being a consumer grade unit, I use a Linksys WRT 1900AC in my bedroom. 2.4G for my mobile phone and 5.0G for my Microsoft Surface devices. 75M up & down.
I also placed various Linksys routers and a few Range Extenders around my church. No complaints other than Verizon won't give us FiOS, forcing us to make due with 7M down 768K up DSL service.
