I need help determining how best to maximize the speed and throughput offered by FIOS and also ensure strong wireless coverage throughout the house. FIOS enters and the cable modem is situated at the west end of the basement. The footprint The home has wired Ethernet throughout. Currently, an ASUS RT-N66 wireless router is located on the first floor about 20 feet southeast of the modem location and is set as an Access Point. Sometimes the 5G signal from the router doesn't even reach 15 feet line of site or around the corner in another room. There are two gaming consoles in use over wireless and several wireless devices (iPhones and iPads). I would like strong wireless coverage throughout the house and also desire minimal performance degradation over the wired network. There are several wired switches in use for 3 printers, 6 computers/laptops and 2 NAS devices. I would also like to be able to stream video from network storage without issue. Not sure if I would need two or three access points, the house is 3,500 sq ft and basically 3 floors - there is a bedroom in the basement at the opposite end from the cable modem, and a sunroom, also wired, above the bedroom. I am not well versed in networking, so I am quite confused as to what I actually need here - a better router? What type of dual band access point will suffice as a cost effective solution? It's possible to wire one, maybe both gaming consoles, but that is the only change I could make in that regard. We also use Netflix via wired blu-ray player. Any help would be appreciated, especially specifics as to brand/model of equipment to purchase. I wouldn't be able to mount ceiling AP's. Thanks.
