How Do I Configure My DOCSIS Residential Gateway?

 

Field Name

Description

 

 

Afterburner

Allows you to enable or disable Afterburner Technology

 

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

Allows you to set the fragmentation threshold. This

 

Threshold

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
