ADVANCE WIRELESS SETTINGS
Wireless Channel:
The Wireless Channel can let you select the channel of
your access point. Channel availability is different for different
countries due to their regulation.
Fragmentation Threshold:
Maximum frame size. Frame larger than the threshold are
fragmented into multiple packets and transmitted. The
range is 256~2346 bytes.
If a network packet is smaller than the preset
RTS Threshold:
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
1~2347 bytes.
Interval of the Delivery Traffic Indication
DTIM Interval (ms):
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,
This value indicates the frequency
Beacon Interval (ms):
interval of the beacon. A beacon is a packet broadcast by the
router to synchronize the wireless network. The value is
1~65535 milliseconds.
5-levels of transmit power are available:
Transmit Power:
20%, 40%, 60%, 80% and 100%.
