Access point Settings: These are the settings of the access point. You can configure the  
rules to allow wireless-equipped computers and other devices to communicate with a wireless  
network.  
Access point: Select Activated to allow wireless station to associate with the access  
point.  
Channel: Select your region and the channel you want to use from the drop-down List of  
Channel. This field determines which operating frequency will be used. It is not  
necessary to change the default channel unless you notice interference problems with  
another nearby access point.  
Transmit Power: Here you can specify the transmit power of Router. You can select  
High, Medium or Low which you would like. High is the default setting and is  
recommended.  
Beacon Interval: Enter a value between 20-1000 milliseconds. The Beacon Interval  
value indicates the frequency interval of the beacon. A beacon is a packet broadcast by  
the Router to synchronize the wireless network. The default value is 100.  
RTS/CTS Threshold: 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. In most cases,  
keep its default value of 2347.  
Fragmentation Threshold: This value specifies the size for a packet. When packet size  
exceeds the fragmentation threshold, the packet will be fragmented into multiple packets.  
Setting the Fragmentation Threshold too low may result in poor network performance. In  
most cases, it should remain at its default value of 2346.  
DTIM: This value, between 1 and 255, indicates the interval of the Delivery Traffic  
Indication 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 messages 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 messages. The default value is 1.  
Wireless Mode: In the drop-down list you can select “802.11b”, “802.11g”, “802.11n”,  
“802.11b+g”, “802.11g+n” and “802.11b+g+n”. “802.11b+g+n” allows 802.11b, 802.11g  
and 802.11n wireless stations to connect to the Router.

4.4.5 VLAN  
Choose “Advanced SetupVLAN”, you can activate the VLAN function in the next screen.  
Virtual LAN (VLAN) is a group of devices on one or more LANs that are configured so that they  
can communicate as if they were attached to the same LAN, when in fact they are located on a  
number of different LAN segments. Because VLANs are based on logical instead of physical  
connections, it is very flexible for user/host management, bandwidth allocation and resource  
optimization. There are two types of VLAN as follows:  
Port-Based VLAN: Each physical switch port is configured with an access list specifying  
membership in a set of VLANs.  
ATM VLAN: Using LAN Emulation (LANE) protocol to map Ethernet packets into ATM cells and  
deliver them to their destination by converting an Ethernet MAC address into an ATM address.
