VigorAP 902 is a highly integrated wireless local area network (WLAN) for 5 GHz 802.11ac
or 2.4/5 GHz 802.11n WLAN applications. It supports channel operations of 20/40 MHz at
2.4 GHz and 20/40/80 MHz at 5 GHz. VigorAP 902 can support data rates up to 867 MBps
in 802.11ac 80 MHz channels.
Note :
*
The actual data throughput will vary according to the network conditions and
environmental factors, including volume of network traffic, network overhead and
building materials.
In an Infrastructure Mode of wireless network, VigorAP 902 plays a role as an Access Point
(AP) connecting to lots of wireless clients or Stations (STA). All the STAs will share the
same Internet connection via VigorAP 902. The
General Setup will set up the information
of this wireless network, including its SSID as identification, located channel etc.

WEP (Wired Equivalent Privacy) is a legacy method to encrypt each frame transmitted via
radio using either a 64-bit or 128-bit key. Usually access point will preset a set of four keys
and it will communicate with each station using only one out of the four keys.
WPA (Wi-Fi Protected Access), the most dominating security mechanism in industry, is
separated into two categories: WPA-personal or called WPA Pre-Share Key (WPA/PSK),
and WPA-Enterprise or called WPA/802.1x.
In WPA-Personal, a pre-defined key is used for encryption during data transmission. WPA
applies Temporal Key Integrity Protocol (TKIP) for data encryption while WPA2 applies
AES. The WPA-Enterprise combines not only encryption but also authentication.
Since WEP has been proved vulnerable, you may consider using WPA for the most secure
connection. You should select the appropriate security mechanism according to your needs.
No matter which security suite you select, they all will enhance the over-the-air data
protection and /or privacy on your wireless network. The VigorAP 902 is very flexible and
can support multiple secure connections with both WEP and WPA at the same time.
