Set the transmit power of the antennas.

Beacons are packets sent by an Access Point to synchronize a wireless network. Specify a value. 100 is the default setting and is recommended.

This value should remain at its default setting of 2432. If inconsistent data flow is a problem, only a minor modification should be made.

The fragmentation threshold, which is specified in bytes, determines whether packets will be fragmented. Packets exceeding the 2346 byte setting will be fragmented before transmission. 2346 is the default setting.

(Delivery Traffic Indication Message) 1 is the default setting. A DTIM is a countdown informing clients of the next window for listening to broadcast and multicast messages.

Select Short or Long Preamble. The preamble defines the

length of the CRC block (Cyclic Redundancy Check is a common technique for detecting data transmission errors) for communication between the wireless router and the roaming wireless network adapters. Note: High network traffic areas should use theShort Preamble type.

Use the drop-down menu to select the wireless modes you want to enable on the router. The available options are 802.11n only, 802.11 Mixed(g/b), and 802.11 Mixed(n/g/b).

This setting can be used to adjust the bandwidth of the wireless signal. The default setting is 20/40 MHz (Auto).

Check this box to reduce the guard interval time therefore increasing the data capacity. However, it’s less reliable and may create higher data loss.
