How Do I Configure My DOCSIS Residential Gateway?
Field Name
Description
Afterburner
Technology
Allows you to enable or disable Afterburner Technology
Rate
Allows you to fix the data rate for wireless connections.
The following data rates are available:
Auto (factory default), 1 Mbps, 2 Mbps, 5.5 Mbps,
6 Mbps, 9 Mbps, 11 Mbps, 12 Mbps, 18 Mbps,
24 Mbps, 36 Mbps, 48 Mbps, 54 Mbps
Note:
In the automatic mode, data rate is a function of
signal strength and signal quality.
Output Power
Allows you to adjust the relative output power of your
gateway wireless transmitter. The following settings are
available:
100% (factory default), 75%, 50%, and 25%
Beacon Interval
Displays the time interval that the WAP uses to
announce itself to remote devices. The Beacon Interval
should be left at 100ms for compliance with most client
cards. The Beacon Interval specifies how often packets
are sent by the Access Point (AP) to synchronize a
wireless network and its clients
DTIM Interval
Displays the time interval between
Broadcasts/Multicast transmissions. The DTIM
(Delivery Traffic Indication Message) Interval is a
countdown informing the wireless 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 DTIM Interval should be left at
3 ms for compliance with most client cards
Fragmentation
Threshold
Allows you to set the fragmentation threshold. This
threshold should be set equivalent to the maximum
Ethernet frame size allowable on the link including
overhead (1536 bytes). Lesser settings can damage data
throughput as large frames could be fragmented or
collisions could occur. The factory default is 2346
RTS Threshold
Determines at what packet size beyond which the ready
to send/clear to send (RTS/CTS) mechanism is invoked.
The factory default is 2347
Short Retry Limit
The number of times the gateway transmits an
unacknowledged unicast frame that is shorter than the
RTS threshold before discarding the frame. The factory
default is 7
