Netgear WAC720- ProSAFE® Business 2 x 2 Dual Band Wireless-AC Access Point 사용자 설명서

Placing an external antenna in a vertical position provides best side-to-side coverage. 
Placing an external antenna in a horizontal position provides best up-and-down 
coverage. (An external antenna does not come standard with the access point.)

If you are using multiple access points, it is better if adjacent access points use different radio 
frequency channels to reduce interference. The recommended channel spacing between 
adjacent access points is five channels (for example, use Channels 1 and 6, or 6 and 11, or 1 
and 11).

The time it takes to establish a WiFi connection can vary depending on both your security 
settings and placement. 

The access point connects to your LAN using twisted-pair Category 5 Ethernet cable with 
RJ-45 connectors.

For the initial configuration of your access point, you must connect a computer to the access 
point.

To connect to the access point on your network, your WiFi device must support 802.11b, 
802.11g, 802.11n, 802.11a, or 802.11ac. If your computer does not include an internal WiFi 
adapter, we recommend using the NETGEAR A6210 WiFi USB Adapter.

You do not need to change the operating frequency (channel) unless you notice interference 
problems or you place the access point near another access point. If you do change the 
operating frequency, observe the following guidelines:

Access points use a fixed channel. You can select a channel that provides the least 

interference and best performance. In the United States and Canada, 11 channels are 
available.

If you use multiple access points, it is better if adjacent access points use different 
channels to reduce interference. The recommended channel spacing between adjacent 
access points is five channels (for example, use Channels 1 and 6, or 6 and 11).

In infrastructure mode (which is the default mode for the access point), WiFi stations 
normally scan all channels, looking for a access point. If more than one access point can 
be used, the one with the strongest signal is used. This is possible only if the access 
points use the same SSID.
