Turn off for maximized throughput. Turn on for greater security.
The option to provide wireless Internet access only to clients who are operating at 802.11n
speeds.
Reduced Inter Frame Spacing (RIFS) is a required 802.11n feature that improves
performance by reducing the amount of dead time required between transmissions. We
recommend this option Off unless your network administrator advises otherwise.
Overlapping Basic Service Sets (OBSS) co-existence provides a method for basic service
sets to share a single frequency.
This option provides a means to save power on the receiving wireless signal.
The time interval before Rx Chain Power Save is implemented.
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.
Setting for multicast packet transmission rate. (1-54 Mbps).
Sets basic transmission rate.
A threshold (in bytes) determines whether packets will be fragmented and at what size.
Packets that exceed the fragmentation threshold of an 802.11 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.
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.
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 value is 1.
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.
Here you have the option of setting the limit of the number of clients who can connect to your
wireless network.
Broadcom's Xpress™ Technology is compliant with draft specifications of two planned
wireless industry standards. It has been designed to improve wireless network efficiency. The
default value is disabled.
The option of decreasing the transmitting power of your wireless signal
WMM is a standard created to define quality of service (QoS) in WiFi networks. WMM adds
prioritized capabilities to WiFi networks and optimizes their performance when multiple
concurring applications, each with different latency and throughput requirements, compete
for network resources.
WMM No Acknowledgement gives you the option of whether to send acknowledgement
frames with WMM data packets.
WMM Automatic Power Save Delivery, a feature of that allows the router to save power. This
option is enabled by default.
