DESCRIPTIONS
Set the output power of the NWA in this field. If there is a high
density of APs in an area, decrease the output power of the NWA to
reduce interference with other APs. Select from 100% (Full
Power), 50%, 25%, 12.5% and Minimum. See the product
specifications for more information on your NWA's output power.
Note: Reducing the output power also reduces the NWA's
effective broadcast radius.
This section controls the data rates permitted for clients.
For each Rate, select an option from the Configuration list. The
options are:
• Basic (1~11 Mbps only): Clients can always connect to the
access point at this speed.
• Optional: Clients can connect to the access point at this speed,
when permitted to do so by the AP.
• Disabled: Clients cannot connect to the access point at this
speed.
The MCS Rate table is available only when 802.11n/g or
802.11n/a is selected as the 802.11 Radio Mode.
IEEE 802.11n supports many different data rates which are called
MCS rates. MCS stands for Modulation and Coding Scheme. This is
an 802.11n feature that increases the wireless network performance
in terms of throughput.
For each MCS Rate (0-15), select either Enable (default) to have the
NWA use the data rate. Select Disable if you do not want the NWA
to use the data rate.
Select this to turn on security for the NWA's Wireless Distribution
System (WDS). A Wireless Distribution System is a wireless
connection between two or more APs. If you do not select the check
box, traffic between APs is not encrypted.
Note: WDS security is independent of the security settings
between the NWA and any wireless clients.
When you enable WDS security, also do the following:
• Select the type of security you want to use (TKIP or AES) to
secure traffic on your WDS.
• Enter a pre-shared key in the PSK field for each access point in
your WDS. Each access point can use a different pre-shared key.
• Configure WDS security and the relevant PSK in each of your
other access point(s).
Note: Other APs must use the same encryption method to
enable WDS security.
