2. Beacon Interval

The device broadcasts beacon frames regularly to announce its existence. The
beacon Interval specifies how often beacon frames are transmitted in time unit of
milliseconds. The default value is 100, and a valid value should be between 1 and
1000.

3. Transmit Power

4. RTS Threshold

RTS/CTS frames are used to gain control of the medium for transmission. Any unicast
(data or control) frames larger than specified RTS threshold must be transmitted
following the RTS/CTS handshake exchange mechanism. The RTS threshold should
have a value between 256-2347 bytes, with a default of 2347. It is recommended that
this value does not deviate from the default too much.

5. Fragmentation

When the size of a unicast frame exceeds the fragmentation threshold, it will be
fragmented before the transmission. It should have a value of 256-2346 bytes, with a
default of 2346. If you experience a high packet error rate, you should slightly
decrease the Fragmentation Threshold.

6. DTIM interval

The AIRMAX5 buffers packets for stations that operate in the power-saving mode.
The Delivery Traffic Indication Message (DTIM) informs such power-conserving
stations that there are packets waiting to be received by them. The DTIM interval
specifies how often the beacon frame should contain DTIMs. It should have a value
between 1 to 255, with a default value of 3.

7. WMM Capable

Enable or disable WMM Capable.

8. TX Rates

You can adjust the transmit output power of the N450R. The higher the output power,
the larger coverage N450R can deliver. However, it is advised that you use just
enough output power so it will not create excessive interference for the environment.
Also, using too much power at close distance can create serious performance drop
due to signal distortion.
