Hi I want to set up a wifi network on the ground floor of a condominium building I live in. 3 APs will be indoors, 1 outdoors, and possibly another indoor AP I'm not sure about. So 4-5 total APs. Ideally I would like a wired backhaul to all APs since the walls are concrete and a wireless backhaul is only possible for 2 of the APs (if wireless it would come from another AP getting a wired backhaul). What do you guys recommend for this? Should I mix and match wired AP conventional routers of the same make and model except for the outdoor AP or do I stand to benefit from some sort of wifi system like Ubiquiti? What are my options? The most important thing is roaming capability, speed is not that important and coverage is only important for the outdoor AP; the indoor ones don't have much area to cover. Thanks!
