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 > 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.

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.
