This section introduces advanced configuration for the wireless access point. If you are not familiar with the
following functions, keep the default parameters. In some cases, incorrect settings may reduce wireless
performance.
Wireless Settings → Advanced
Authentication Type: Select the type of authentication.
Open System - Any wireless client can associate with the wireless access point but the client must
have the same WEP key to exchange data.
Shared Key - Wireless clients must have the same WEP key to associate with wireless access point
and exchange data.
Auto – Auto-detect the authentication type.
Fragmentation: A packet can be fragmented into small units to pass over a network medium that can not
support the original packet size. If you encounter a busy network, a lower value of Fragment Threshold
could improve performance. If the traffic flows are not very busy, a higher Fragment Threshold provides
good network performance. In most case, keeping the default value=2346 is recommended.
RTS Threshold: RTS Threshold is a mechanism to implement in collision avoidance. In a large wireless
network, two stations do not hear each other but can hear wireless access point. When the two send data
to Access Point at the same time, it may result in data collision and a loss of messages for both wireless
stations. In most case, keeping the default value=2347 is recommended.
Beacon Interval: The default value is 100. The Beacon Interval indicates the frequency interval of target
beacon transmission time which can be found in a packet body. The Gateway transmits the beacon packet
to help a wireless client to identify the existence of nearby access point. If the beacon intervals are too long,
it would be hard to access the network. If the beacon intervals are too short, the resources would be
wasted.
