Advanced Wireless

AP Isolaton

This isolates all wireless clients and wireless

devices on your network from each other. Wireless devices

will be able to communicate with the Router but not

with each other. To use this function, select Enabled. AP

Isolation is disabled by default.

Frame Burst

Enabling this option should provide your

network with greater performance, depending on the

manufacturer of your wireless products. To use this option,

keep the default, Enabled. Otherwise, select Dsabled.

Authentcaton Type

The default is set to Auto, which

allows either Open System or Shared Key authentication

to be used. With Open System authentication, the sender

and the recipient do NOT use a WEP key for authentication.

With Shared Key authentication, the sender and recipient

use a WEP key for authentication. Select Shared Key to

only use Shared Key authentication.

Basc Rate

The Basic Rate setting is not actually one rate

of transmission but a series of rates at which the Router

can transmit. The Router will advertise its Basic Rate to the

other wireless devices in your network, so they know which

rates will be used. The Router will also advertise that it will

automatically select the best rate for transmission. The

default setting is Default, when the Router can transmit

at all standard wireless rates (1-2Mbps, 5.5Mbps, 11Mbps,

18Mbps, and 24Mbps). Other options are -2Mbps, for

use with older wireless technology, and All, when the

Router can transmit at all wireless rates. The Basic Rate

is not the actual rate of data transmission. If you want to

specify the Router’s rate of data transmission, configure

the Transmission Rate setting.

Transmsson Rate

The rate of data transmission should

be set depending on the speed of your wireless network.

You can select from a range of transmission speeds, or you

can select Auto to have the Router automatically use the

fastest possible data rate and enable the Auto-Fallback

feature. Auto-Fallback will negotiate the best possible

connection speed between the Router and a wireless

client. The default is Auto.

N Transmsson Rate

The rate of data transmission

should be set depending on the speed of your Wireless-N

networking. You can select from a range of transmission

speeds, or you can select Auto to have the Router

automatically use the fastest possible data rate and enable

the Auto-Fallback feature. Auto-Fallback will negotiate the

best possible connection speed between the Router and a

wireless client. The default is Auto.

CTS Protecton Mode

The Router will automatically

use CTS (Clear-To-Send) Protection Mode when your

Wireless-N and Wireless-G products are experiencing

severe problems and are not able to transmit to the

Router in an environment with heavy 802.11b traffic. This

function boosts the Router’s ability to catch all Wireless-

N and Wireless-G transmissions but will severely decrease

performance. The default is Auto.

Beacon Interval

Enter a value between 20 and 999

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 00.

DTIM Interval

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 .

Fragmentaton Threshold

This 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

Should you encounter inconsistent data

flow, only minor reduction of the default value, 234, 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. The RTS

Threshold value should remain at its default value of

234.

Security > Firewall

The Firewall screen is used to configure a firewall that can

filter out various types of unwanted traffic on the Router’s

local network.
