Description
54g
TM
Mode
Auto by default.
Basic Rate Set
Select the wireless transmission rate to a particular speed or leave it
as default (Auto) to allow the AP adjusts speed automatically.
54g
TM
Protection
In Auto mode (Protection ON), the device will use RTS/CTS
control to improve 802.11g performance in mixed networks.
Turning protection OFF will maximize 802.11g throughput under
most conditions.
XPress
TM
Technology
When Xpress is turned on, aggregate throughput can improve
significantly.
Afterburner
TM
Technology
Afterburner technology is an enhancement for the 54g™ platform,
Broadcom's maximum performance implementation of the IEEE
802.11g standard.
Rate
Forces the transmission rate for the cable modem/router to a
particular speed. Auto will provide the best performance in nearly
all situations.
Beacon Interval
A beacon is a packet broadcast by the router to synchronize the
wireless network. The default interval is 100 ms.
DTIM Interval
Interval of the Delivery Traffic Indication Message (DTIM). A
DTIM field is a countdown field informing clients of the next
window for listening to broadcast and multicast messages. When
the router has buffered broadcast or multicast for associated clients,
it sends the next DTIM with a DTIM Interval value. Its clients hear
the beacons and awaken to receive the broadcast and multicast
message. The default value is 1.
Fragmentation Threshold
This value specifies the maximum size for a packet before data is
fragmented into multiple packets. If you experience a high packet
error rate, you may slightly increase the fragmentation threshold.
Setting the fragmentation threshold too low may result in poor
network performance. Only minor reduction of the default value is
recommended. In most cases, it should remain at its default value
of 2346.
RTS Threshold
Using this setting can regulate your wireless network if you
experience any inconsistent data flow. Make only minor
adjustments to the default value of 2347.
NPHY Rate
Set the Physical Layer (NPHY) rate. These rates are only applicable
when the
802.11n mode
is configured as
Automatic
.
802.11n Protection
The 802.11g standards provide a protection method so 802.11g and
802.11b devices can co-exist in the same network without
“speaking” at the same time. Do not disable 802.11n protection if
