Wireless
N Transmission Rate
The rate of data transmission should be set depending on the speed of your
Wireless-N networking. Select from a range of transmission speeds, or select
Auto
to have the device automatically use the fastest possible data rate and enable the
Auto-Fallback feature. Auto-Fallback negotiates the best possible connection speed
between the device and a wireless client. The factory default setting is
Auto
.
Choose one of the following options for transmission rate:
Auto (factory default)
Use Legacy Rate
0: 6.5 or 13.5 Mbps
1: 13 or 27 Mbps
2: 19.5 or 40.5 Mbps
3: 26 or 54 Mbps
4: 39 or 81 Mbps
5: 52 or 108 Mbps
6: 58.5 or 121.5 Mbps
7: 65 or 135 Mbps
8: 13 or 27 Mbps
9: 26 or 54 Mbps
10: 39 or 81 Mbps
11: 52 or 108 Mbps
12: 78 or 162 Mbps
13: 104 or 216 Mbps
14:117 or 243 Mbps
15: 130 or 270 Mbps
CTS Protection Mode
CTS (Clear-To-Send) Protection Mode boosts the device's ability to catch all wireless
transmissions, but can severely decrease performance. Select
Auto
to use this
feature when needed, when the Wireless-N/G products are not able to transmit to
the device in an environment with heavy 802.11b traffic. Select
Disable
to
permanently disable this feature.
Beacon Interval
The Beacon Interval value indicates the frequency interval of the beacon. A beacon
is a packet broadcast by the device to synchronize the wireless network.
(Default: 100 msec, Range: 20-1000)

Field Description
DTIM Interval
The Delivery Traffic Indication Message (DTIM) indicates the interval between
Broadcasts/Multicast transmissions. DTIM field is a countdown field informing
clients of the next window for listening to broadcast and multicast messages. When
the device 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.
(Default: 1, Range: 1-255)
Fragmentation Threshold
The fragmentation threshold value specifies the maximum size for a packet before
data is fragmented into multiple packets. If you experience a high packet error rate,
you may slightly increase the Fragmentation Threshold. Setting the Fragmentation
Threshold too low may result in poor network performance. Only minor reduction
of the default value is recommended. In most cases, it should remain at its default
value of 2346.
RTS Threshold
The RTS Threshold determines at what packet size beyond which the ready to
send/clear to send (RTS/CTS) mechanism is invoked. Should you encounter
inconsistent data flow, only minor reduction of the default value, 2346, is
recommended. If a network packet is smaller than the preset RTS Threshold size,
the RTS/CTS mechanism will not be enabled. The device 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. The RTS Threshold
value should remain at its default value of 2347.

Wireless > WDS Settings
The Wireless Distribution System (WDS) Settings page allows you to expand the
coverage of your wireless network by deploying signal repeaters.
Make sure the
channel settings are the same for all WDS enabled devices.
Select the
WDS Settings
tab to open the Wireless WDS Settings page. Use this page
to configure the WDS settings.
Wireless WDS Settings Page Description
Use the descriptions and instructions in the following table to configure the wireless
distribution system settings for your residential gateway. After you make your
selections, click
Save Settings
to apply your changes or
Cancel Changes

Allow Wireless Signal To Be Repeated by a Repeater
Check this box to allow a wireless client to connect to a repeater and route
traffic between the wireless client and a repeater. A maximum of 3
repeaters are allowed.
Remote Access Point's MAC Address (MAC 1 through 3)
Use the three fields (MAC 1, 2, and 3) to enter the MAC address of the

Wireless > QoS
Quality of Service (QoS) ensures better service to high-priority types of network
traffic, which may involve demanding, real-time applications, such as video
conferencing. QoS settings allow you to specify priorities for different types of
traffic. Lower priority traffic will be slowed down to allow greater throughput or
less delay for high priority traffic. Select the
QoS
tab to open the Wireless QoS page.
Wireless QoS Page Description
Use the descriptions and instructions in the following table to configure each QoS
setting. After you make your selections, click

Field Description
No ACK
Allows you to enable or disable NO ACK. This feature is
recommended for data services where transmission is
important and packet loss is tolerable to a certain degree. If
you select
Disable
, an acknowledge packet is returned for
every packet received. This provides a more reliable
transmission, but it increases traffic load, which decreases
performance.
