Slot Time: Choose short or long slot time. The slot time is the amount of time a device waits
after a collision before retransmitting.
Protection Mode:
None: There is no protection before sending out any packet.
Always: There is always a protection frame sending out before actual data packet transmitting.
The exact protection frame sending out depends on the protection type.
Auto: The protection frame depends on RTS/CTS threshold and size of packet. When packet size
is bigger than threshold the protection frame is sending out.
Protection Type:
RTS-CTS : If enable RTS/CTS on a particular station, it will refrain from sending a data frame
until the station completes a RTS/CTS handshake with another station, such as an access point.
A station initiates the process by sending a RTS frame. The access point receives the RTS and
responds with a CTS frame. The station must receive a CTS frame before sending the data
frame. The CTS also contains a time value that alerts other stations to hold off from accessing the
medium while the station initiating the RTS transmits its data.
The RTS/CTS handshaking provides positive control over the use of the shared medium. The
primary reason for implementing RTS/CTS is to minimize collisions among hidden stations.
CTS only : A node send CTS frame itself. This feature no need to wait receiving RTS frame.
RTS/CTS Threshold: RTS/CTS packet size threshold is 0-2347 octects. If the packet size the
node wants to transmit is larger than the threshold, the RTS/CTS handshake gets triggered. If the
packet size is equal to or less than threshold the data frame gets sent immediately.
Wireless > MAC Address Control
This page allows you to specify which wireless computer can access the Internet and which
wireless computer cannot access the Internet. The specified MAC address and the policy for the
computer are reflected in the table.
Enable Wireless MAC Control: Tick to enable Wireless MAC Control.
Default Policy: This policy determines whether computers, whose MAC addresses are not in the
table, are able to access the Internet. If you choose Deny All, all computer associated to the
Router will not be able to access the Internet other than those specified in the table.
MAC Address: Enter the MAC address of the computer. The format for the MAC address is
aa:bb:cc:dd:ee:ff.
Policy: Choose to deny or allow the computer to access the computer. Click on the Add button to
add the policy.
