What is an Access Point?

Internet access points are devices that create a wireless local area network, or WLAN, usually in an office or large building. An access point connects to a wired router, switch, or hub via an Ethernet cable, and projects a Wi-Fi signal to a designated area.
For example, if you want to enable Wi-Fi access in your company’s reception area but don’t have a router within range, you can install an access point near the front desk and run an Ethernet cable through the ceiling back to the server room.

What Is a Range Extender?
As its name implies, a range extender lengthens the reach of an existing Wi-Fi network. Since range extenders connect wirelessly to Wi-Fi routers, they must be placed where the Wi-Fi router’s signal is already strong, not in the location of the actual dead spot.
For instance, if your router is in the basement of a two-story building, installing a range extender on the ground floor (where coverage from the Wi-Fi router is still strong) will eliminate potential dead zones on the second floor.
