and a wireless client. The default value is Auto.
Select the basic transmission rate ability for the AP.
Packets that are larger than this threshold are fragmented into multiple
packets. Try to increase the fragmentation threshold if you encounter
high packet error rates. Do not set the threshold too low, since this can
result in reduced networking performance.
This value should remain at its default setting of 2347.Should you
encounter inconsistent data flow, only minor reductions are
recommended. Should you encounter inconsistent data flow, only
minor reduction of the default value, 2347, is recommended. 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 RTS Threshold value should remain at
its default value of 2347.
Enter a value between 1 and 255 for the Delivery Traffic Indication
Message (DTIM.) A DTIM is a countdown informing clients of the next
window for listening to broadcast and multicast messages.
A beacon is a packet of information that is sent from a connected
device to all other devices where it announces its availability and
readiness. A beacon interval is a period of time (sent with the beacon)
before sending the beacon again. The beacon interval may be adjusted
in milliseconds (ms). Default (100) is recommended.
Select Enable or Disable. This is a special accelerating technology for
IEEE802.11g. The defaule is Disabled.
Adjust the transmission range here. This tool can be helpful for security
purposes if you wish to limit the transmission range.
Select whether WMM is enable or disabled. Before you disable WMM,
you should understand that all QoS queues or traffic classes relate to
wireless do not take effects.
Select whether ACK in WMM packet. By default, the 'Ack Policy' for
each access category is set to Disable, meaning that an acknowledge
packet is returned for every packet received. This provides a more
reliable transmission but increases traffic load, which decreases
performance. To disable the acknowledgement can be useful for Voice,
for example, where speed of transmission is important and packet loss
is tolerable to a certain degree.
APSD is short for automatic power save delivery, Selecting enable will
