How Do I Configure the Cable Modem Gateway?

 

 

 

Field Name

Description

 

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

 

 

 

 

Configuring Wireless Access Point Access Control

Use the Setup Wireless - Access Control page to configure your configure your wireless access point access control.
