The Wireless Tab - Wireless MAC Filter

Wireless access can be filtered by using the MAC addresses of the wireless devices transmitting within your

network’s radius.

Wireless MAC Filter

. To filter wireless users by MAC Address, either permitting or blocking access, click

Enable

.

If you do not wish to filter users by MAC Address, select

Disable

.

Prevent

. Clicking this button will block wireless access by MAC Address.

Permit Only

. Clicking this button will allow wireless access by MAC Address.

Edit MAC Address Filter List

. Clicking this button will open the MAC Address Filter List. On this screen, you can

list users, by MAC Address, to whom you wish to provide or block access. For easy reference, click the

Wireless

Client MAC List

button to display a list of network users by MAC Address.

The Wireless Tab - Advanced Wireless Settings

Wireless-G Broadband Router with SpeedBooster

The Wireless Tab - Advanced Wireless Settings

This tab is used to set up the Router’s advanced wireless functions. These settings should only be adjusted by an

expert administrator as incorrect settings can reduce wireless performance.

Authentication 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.

Basic 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

1-2Mbps

, 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.

Transmission 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 value is

Auto

.

CTS Protection Mode

. CTS (Clear-To-Send) Protection Mode should remain disabled unless you are having

severe problems with your Wireless-G products not being 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-G transmissions but will

severely decrease performance.

Frame Burst

. Enabling this option should provide your network with greater performance, depending on the

manufacturer of your wireless products. If you are not sure how to use this option, keep the default,

Disable

.

Beacon Interval

. The default value is

100

. Enter a value between 1 and 65,535 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.

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

1

.

Fragmentation 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,

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. The RTS Threshold value should remain at its default value

of

2347

.

The Security Tab - Firewall

Firewall Protection

. Enable this feature to employ Stateful Packet Inspection (SPI) for more detailed review of

data packets entering your network environment.

Block WAN Requests

. Enable the Block WAN Request feature by checking the box beside

Block Anonymous

Internet Requests

and you can prevent your network from being “pinged,” or detected, by other Internet users.

The Block WAN Request feature also reinforces your network security by hiding your network ports. Both

functions of the Block WAN Request feature make it more difficult for outside users to work their way into your

network. This feature is enabled by default.

The Security Tab - VPN Passthrough

Use the settings on this tab to allow VPN tunnels using IPSec, PPTP, or L2TP protocols to pass through the

Router’s firewall.

IPSec Pass-through

. Internet Protocol Security (IPSec) is a suite of protocols used to implement secure

exchange of packets at the IP layer. To allow IPSec tunnels to pass through the Router, click

Enable

.

IPSec Pass-

Through is enabled by default.

PPTP Pass-through

. Point-to-Point Tunneling Protocol (PPTP) allows the Point-to-Point Protocol (PPP) to be

tunneled through an IP network. To allow PPTP tunnels to pass through the Router, click

Enable

. PPTP Pass-

Through is enabled by default.

L2TP Pass-through

. Layer 2 Tunneling Protocol is the method used to enable Point-to-Point sessions via the

Internet on the Layer 2 level. To allow L2TP tunnels to pass through the Router, click

Enable

. L2TP Pass-Through

is enabled by default.
