LABEL | DESCRIPTION |
Preamble Type | Select Dynamic to have the AP automatically use short preamble when wireless adapters |
| support it, otherwise the AP uses long preamble. |
| Select Long if you are unsure what preamble mode the wireless adapters support, and to |
| provide more reliable communications in busy wireless networks. |
|
|
RTS/CTS | (Request To Send) The threshold (number of bytes) for enabling RTS/CTS handshake. |
Threshold | Data with its frame size larger than this value will perform the RTS/CTS handshake. |
| Setting this attribute to be larger than the maximum MSDU (MAC service data unit) size |
| turns off the RTS/CTS handshake. Setting this attribute to its smallest value (1) turns on |
| the RTS/CTS handshake. |
|
|
Fragmentation | The threshold (number of bytes) for the fragmentation boundary for directed messages. It |
| is the maximum data fragment size that can be sent. |
|
|
Extension | You can use CTS to self or |
Channel | wireless networks or hidden wireless clients. The throughput of |
Protection Mode | than CTS to self. Using this mode may decrease your wireless performance. |

|
This field is available only when 802.11 b/g/n is selected as the Wireless Mode. | |
Aggregation | Select to enable |
| |
| Message Protocol Data Unit (MPDU) aggregation collects Ethernet frames along with their |
| 802.11n headers and wraps them in a 802.11n MAC header. This method is useful for |
| increasing bandwidth throughput in environments that are prone to high error rates. |
|
|
Short GI | This field is available only when 802.11 b/g/n is selected as the Wireless Mode. Select |
| Enabled to use Short GI (Guard Interval). The guard interval is the gap introduced |
| between data transmission from users in order to reduce interference. Reducing the GI |
| increases data transfer rates but also increases interference. Increasing the GI reduces |
| data transfer rates but also reduces interference. |
|
|
MCS Rate | The MCS Rate table is available only when 802.11 b/g/n is selected in the Wireless |
| Mode field. |
| 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 |
| rate. |
| Clear the Enabled check box if you do not want the |
| Turn on the Auto option to have the |
| optimize the throughput. |
