Advanced Wireless - D-Link DSL-2640B User Manual

Section 4 - Troubleshooting
These options are for users that wish to change the behavior of their 802.11g wireless radio from the standard setting. D-Link does not recommend
changing these settings from the factory default. Incorrect settings may impair the performance of your wireless radio. The default settings should
provide the best wireless radio performance in most environments.
To access the ADVANCED WIRELESS setting window, click on the Advanced Wireless button in the ADVANCED directory.
ADVANCED WIRELESS SETTINGS
Transmit Power:
3-levels of transmit power are available: High, Medium and
Low.
Beacon Period:
This value indicates the frequency interval of the beacon.
A beacon is a packet broadcast by the router to
synchronize the wireless network. The value is 20~1000
milliseconds.
RTS Threshold:
If a network packet is smaller than the preset RTS
threshold size, the RTS/CTS mechanism will not be
enabled. The router sends Request to Send (RTS) frames
to a particular receiving station and negotiates the sending
of a data frame. After receiving an RTS, the wireless
station responds with a Clear to Send (CTS) frame to
acknowledge the right to begin transmission. The range is
0~2347 bytes.
Fragmentation
Maximum frame size. Frame larger than the threshold are
fragmented into multiple packets and transmitted. The
Threshold:
range is 256~2346 bytes.
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 range is 1~255 milliseconds,
