What an access point actually does
A wireless access point (WAP or AP) plugs into your wired network and broadcasts WiFi from that point. It is not a router — it does not handle your internet connection or hand out IP addresses — and it is not a range extender, which rebroadcasts an existing signal and halves throughput. An AP delivers full-speed WiFi from a fresh wired connection, which is why business sites use several rather than one big router. From $15, all covered by a 12-month Reboot IT warranty.
