Network Address Translation (NAT) is a function of firewall/ routers. 
It translates many IP addresses on one or more networks (LAN, Wi-Fi) 
onto one shared IP address on another network (WAN).


The UniFi AP 6 Lite supports 1.5 Gbps aggregate over 2.4 GHz and 5 GHz 
Wi-Fi for $99:

One should be sufficient for most wood-frame residential/ SOHO 
applications, assuming the signal can get through the walls.  My UniFi 
AP AC Lite is the previous generation.  It is located on a high self 
near the center of our house, and works fine.


Adding more AP's to improve line-of-site (e.g. one AP per room or space) 
and/or to reduce the number of clients per AP (e.g. multiple AP's in 
large rooms or spaces) will help Wi-Fi performance.
