Configuring the Wireless Access Point
Configuring Security Profile (Virtual AP) Settings
WIth VAP, you can set hierarchical management for different categories of
users. A wireless access point can virtualize eight different virtual wireless
access points (AP). Each virtual wireless access point has a different MAC
address, different security access policy (WEP, WPA, WPA-PSK, etc.), and
Channel Mode
Select from three kinds of channel mode: 20MHz, 20/40MHz and
40MHz.
Short GI
Short guard interval (GI) ensures the reliability of data transmis-
sion by enabling the receiving side to parse out the individual data
blocks correctly.
AMPDU
AMPDU (Aggregate MAC Protocol Data Unit) aggregates packets
to improves system throughput.
AMSDU
AMSDU (Aggregate MAC Service Data Unit) aggregates packets
into larger loads increase transmission rates of sending packets.
HT Protect
When enabled, improves transmission rate among 802.11n
devices, and decrease transfer rate of 802.11b/g.
MIMO
MIMO stands for Multiple Input Multiple Output. It refers to the use
of multiple antennas at both the transmitter and receiver to
improve communication performance.
Channel Protection
When enabled, implements protection rules to guarantee that
802.11n transmissions do not cause interference with legacy sta-
tions or access points.
Output Power
Adjust the transmit power of the radio signal. The greater the out-
put power is, the wireless signal coverage is greater, but it also
means higher power consumption and greater interference with
neighboring devices.
Enable Auto Power
Automatically adjust output power depending on the signal
strength of the wireless terminal that the wireless access point is
connected or trying to connect to.
Enable Auto
Frequency Adjust
Detect all available channels, and select a relatively clean chan-
nel (least occupied by other APs) to work.
When the signal strength of neighboring wireless access points is
below the minimum threshold, the wireless access point will
ignore the device.
User Control Mode
Users: When the connected station exceeds the set number of
users, the device will refuse to connect new users.
Flux: When the bandwidth exceeds the set flux rate, the device
will reject the new user's connection.
Throughput Control
Mode
MAC Address mode: Set the appropriate bandwidth in the
Access Control page according to the MAC address of the client.
AP mode: Restrict all the bandwidth access to the AP client. You
can limit client bandwidth by setting the maximum throughput.
VAP (SSID) mode: Restrict the client's bandwidth attached to this
profile (SSID).
