I am looking to upgrade my Wireless network. The house is large and I have an ASUS 3100. It doesn't reach well into other areas and we have a lot of wireless devices...Give or take we have between 20-30 devices at anytime connected to the wireless. Generally multiple TVs, xboxes, ipads, phones etc. Would it be better to install a mesh network like Amplifi HD Gaming model or add to the router using AiMesh from ASUS?
