Add Additional Wireless Network Name (SSID)
To add additional Wireless Network Names simply add the name to the Multiple SSID field and click on
apply at the bottom of the page. When finished, go to the Security section in this Users Guide for wireless
security configuration.
Multiple SSIDs
Broadcast Network Name (SSID)
This option allows you to hide your wireless network. When this option is set to enable, your wireless
network name is broadcast to anyone within the range of your signal. If you're not using encryption then
they could connect to your network. When this mode is disabled, you must enter the Wireless Network
Name (SSID) on the client manually to connect to the network.
Frequency (Channel)
A wireless network uses specific channels in the wireless spectrum to handle communication between
clients. Some channels in your area may have interference from other electronic devices. Choose the
clearest channel to help optimize the performance and coverage of your wireless network.
Page 31
WDS Mode
When WDS is enabled, this access point functions as a wireless bridge and is able to wirelessly
communicate with other access points via WDS links. A WDS link is bidirectional; both end points must
support WDS and each access point must know the MAC Address of the other. Each access point will be
configured with the remote access point’s MAC address and vice versa. Make sure all access points are
configured with the same SSID, channel and wireless encryption settings.
WDS configuration option enabled
Operating Mode
If you have both wireless g and wireless n client devices included on your wireless network at the same
time, you should choose Mixed Mode. And if you only have wireless n client devices on your wireless
network, you can choose Green Field to enjoy high throughput.
Channel Bandwidth
The "20/40” MHz option is usually best. The other option is available for special circumstances.
Guard Interval
Page 32
Using “Auto” option can increase throughput. However, it can also increase error rate in some
installations, due to increased sensitivity to radio-frequency reflections. Select the option that works best
for your installation.
MCS
The Modulation and Coding Scheme (MCS) is a value that determines the modulation, coding and
number of spatial channels. This parameter represents transmission rate. By default (Auto) the fastest
possible transmission rate will be selected. You have the option of selecting the speed if necessary.
Fix MCS rate for HT rate 0-15
Reserve Direction Grant (RDG)
Disable or enable reserve direction grant. Default is enabled.
Extension Channel
When 20/40 channel bandwidth has been chosen, you should select extension channel to get higher
throughput.
Page 33
Wireless Advanced
Beacon Interval
Beacons are packets sent by a wireless Access Point to synchronize wireless devices. Specify a Beacon
Period value between 20 and 1000. The default value is set to 100 milliseconds.
Data Beacon Rate (DTIM)
A DTIM is a countdown informing clients of the next window for listening to broadcast and multicast
messages. When the wireless Access Point has buffered broadcast or multicast messages for associated
clients, it sends the next DTIM with a DTIM Interval value. Wireless clients detect the beacons and
awaken to receive the broadcast and multicast messages. The default value is 1. Valid settings are
between 1 and 255.
Fragment Threshold
This setting should remain at its default value of 2346. Setting the Fragmentation value too low may
result in poor performance.
RTS Threshold
Page 34
This setting should remain at its default value of 2347. If you encounter inconsistent data flow, only
minor modifications to the value are recommended.
Short Preamble
Use to synchronize communication timing between devices on a network. Disable by default.
Short Slot
Enable or disable short slot. Default is enabled.
Tx Burst
Enable or disable Tx burst. Default is enabled.
Pkt_Aggregate
Enable or disable Pkt aggregate. Default is enabled.
Wi-Fi Multimedia
WMM Capable
Enabling WMM can help control latency and jitter when transmitting multimedia content over a wireless
connection.
APSD Capable
Enable or disable APSD (Adaptive power scheduling protocol) capable. Default is enabled.
*Maximum wireless signal rates are referenced from IEEE 802.11 theoretical specifications. Actual data throughput and
coverage will vary depending on interference, network traffic, building materials and other conditions
Page 35
Wireless MAC Filter
