Option	Description

Band	The new amendment allows IEEE 802.11g units to fall back to speeds of 11 Mbps, so IEEE 802.11b and IEEE 802.11g devices can coexist in the same
	network. The two standards apply to the 2.4 GHz frequency band. IEEE 802.11g creates data-rate parity at 2.4 GHz with the IEEE 802.11a standard,
	which has a 54 Mbps rate at 5 GHz. (IEEE 802.11a has other differences compared to IEEE 802.11b or g, such as offering more channels.)

Channel	Allows selection of a specific channel (1-14) or Auto mode.

Auto Channel	The Auto Channel times the length it takes to scan in minutes.
Timer

802.11n/EWC	An equipment interoperability standard setting based on IEEE 802.11n Draft 2.0 and Enhanced Wireless Consortium (EWC)

Bandwidth	Drop-down menu specifies the following bandwidth: 20MHz in 2.4G Band and 40 MHz in 5G Band, 20MHz in both bands and 40MHz in both bands

Control Sideband	This is available for 40MHz. Drop-down menu allows selecting upper sideband or lower sideband

802.11n Rate	Drop-down menu specifies the following fixed rates. The maximum rate for bandwidth, 20MHz, is 130MHz and the maximum bandwidth, 40MHz, is
	270MHz

802.11n Protection	Turn off for maximized throughput. Turn on for greater security

Support 802.11n	The option to provide wireless Internet access only to clients who are operating at 802.11n speeds
Client Only

54g Rate	In Auto (default) mode, your Router uses the maximum data rate and lowers the data rate dependent on the signal strength. The appropriate setting is
	dependent on signal strength. Other rates are discrete values between 1 to 54 Mbps.

Multicast rate	Setting for multicast packet transmission rate. (1-54 Mbps)

Basic Rate	Sets basic transmission rate.

Fragment	A threshold (in bytes) determines whether packets will be fragmented and at what size. Packets that exceed the fragmentation threshold of an 802.11
Threshold	WLAN will be split into smaller units suitable for the circuit size. Packets smaller than the specified fragmentation threshold value however are not
	fragmented.
	Values between 256 and 2346 can be entered but should remain at a default setting of 2346. Setting the Fragmentation Threshold too low may result in
	poor performance.

RTS Threshold	Request To Send (RTS) specifies the packet size that exceeds the specified RTS threshold, which then triggers the RTS/CTS mechanism. Smaller
	packets are sent without using RTS/CTS. The default setting of 2347 (max length) will disables the RTS Threshold.

DTIM Interval	Delivery Traffic Indication Message (DTIM) is also known as Beacon Rate. The entry range is a value between 1 and 65535. A DTIM is a countdown
	variable that informs clients of the next window for listening to broadcast and multicast messages. When the AP has buffered broadcast or multicast
	messages for associated clients, it sends the next DTIM with a DTIM Interval value. AP Clients hear the beacons and awaken to receive the broadcast
	and multicast messages. The default is 1.

Beacon Interval	The amount of time between beacon transmissions in is milliseconds. The default is 100 ms and the acceptable range is 1 – 65535. The beacon
	transmissions identify the presence of an access point. By default, network devices passively scan all RF channels listening for beacons coming from
	access points. Before a station enters power save mode, the station needs the beacon interval to know when to wake up to receive the beacon.

Global Max Clients	Here you have the option of setting the limit of the number of clients who can connect to your wireless network

Xpress Technology	Broadcom’s Xpress™ Technology is compliant with draft specifications of two planned wireless industry standards. It has been designed to improve
	wireless network efficiency. Default is disabled

Transmit Power	The option of decreasing the transmitting power of your wireless signal

WMM	You can choose the enable or disable WMM which allows for priority of certain data over the wireless network

WMM No	Refers to the acknowledge policy used at the MAC level. Enabling No Acknowledgement can result in more efficient throughput but higher error rates in a
Acknowledgement	noisy Radio Frequency (RF) environment

WMM APSD

Automatic Power Save Delivery. Enable this to save power
