Click Apply button at the bottom of the screen to save the above configurations. You can now configure
other advance sections or start using the Access Point.
There are two authentication types: "Open System" and "Shared Key".
When you select "Open System", wireless stations can associate with this
access point without WEP encryption. When you select "Shared Key", you
should also setup WEP key in the "Encryption" page and wireless stations
should use WEP encryption in the authentication phase to associate with
this access point. If you select "Auto", the wireless client can associate with
this access point by using any one of these two authentication types.
"Fragment Threshold" specifies the maximum size of packet during the
fragmentation of data to be transmitted. If you set this value too low, it will
result in bad performance.
When the packet size is smaller than the RTS threshold, the access point
will not use the RTS/CTS mechanism to send this packet.
The interval of time that this access point broadcast a beacon. Beacon is
used to synchronize the wireless network.
The "Data Rate" is the rate this access point uses to transmit data packets.
The access point will use the highest possible selected transmission rate to
transmit the data packets.
Preamble type defines the length of CRC block in the frames during the
wireless communication. "Short Preamble" is suitable for high traffic
wireless network. "Long Preamble" can provide more reliable
communication.
If you enable "Broadcast ESSID", every wireless station located within the
coverage of this access point can discover this access point easily. If you
are building a public wireless network, enabling this feature is
recommended. Disabling "Broadcast ESSID" can provide better security.
If you enable "IAPP", the access point will automatically broadcast
information of associated wireless stations to its neighbors. This will help
wireless station roaming smoothly between access points. If you have more
than one access points in your wireless LAN and wireless stations have
roaming requirements, enabling this feature is recommended. Disabling
"IAPP" can provide better security.
This is also called CTS Protection. It is recommended to enable the
protection mechanism. This mechanism can decrease the rate of data
collision between 802.11b and 802.11g wireless stations. When the
protection mode is enabled, the throughput of the AP will be a little lower
due to many of frame traffic should be transmitted.
