Access Point (AP) mode is basically when your router isn’t acting like a full router anymore — it just becomes a Wi-Fi hub. Think of it as stripping away the extra stuff (firewall, DHCP, routing, NAT) and just letting your existing main router handle the brains. The AP just throws out a clean wireless signal. That’s it. https://netgerext.net/netgear-r7000-with-ex7000-extend-the-same-wifi-as-access-point/
