The Wireless Tab - Wireless Security

The Wireless Security settings configure the security of your wireless network. There are four wireless security

mode options supported by the Router: WPA Personal, WPA Enterprise, WPA2 Personal, WPA2 Enterprise,

RADIUS, and WEP. (WEP stands for Wired Equivalent Privacy, WPA stands for Wi-Fi Protected Access, which is a

security standard stronger than WEP encryption. WPA2 is stronger than WPA. WPA Enterprise is WPA used in

coordination with a RADIUS server. RADIUS stands for Remote Authentication Dial-In User Service.) These are

briefly discussed here. For detailed instructions on configuring wireless security for the Router, turn to “Appendix

B: Wireless Security.”

Wireless Security

WPA Personal

. WPA gives you two encryption methods, TKIP and AES, with dynamic encryption keys. Select the

type of algorithm,

TKIP

or

AES

. Enter a WPA Shared Key of 8-63 characters. Then enter a Group Key Renewal

period, which instructs the Router how often it should change the encryption keys.

After you have made your changes, click the

Save Settings

button to apply your changes, or click the

Cancel

Changes

button to cancel your changes. For detailed instructions on configuring wireless security for the Router,

turn to “Appendix B: Wireless Security.”

WPA Enterprise

. This option features WPA used in coordination with a RADIUS server. (This should only be used

when a RADIUS server is connected to the Router.) First, select the type of WPA algorithm you want to use,

TKIP

or

AES

. Enter the RADIUS server’s IP Address and port number, along with a key shared between the Router and

the server. Last, enter a Key Renewal Timeout, which instructs the Router how often it should change the

encryption keys.

After you have made your changes, click the

Save Settings

button to apply your changes, or click the

IMPORTANT:

If you are using WPA, always remember

that each device in your wireless network MUST use

the same WPA method and shared key, or else the

network will not function properly.

WPA2 Enterprise

. This option features WPA2 used in coordination with a RADIUS server. (This should only be

used when a RADIUS server is connected to the Router.) First, select the type of WPA algorithm you want to use,

RADIUS

. This option features WEP used in coordination with a RADIUS server. (This should only be used when a

RADIUS server is connected to the Router.) First, enter the RADIUS server’s IP Address and port number, along

with a key shared between the Router and the server. Then, select a Default Transmit Key (choose which Key to

use), and a level of WEP encryption,

64 bits 10 hex digits

or

128 bits 26 hex digits

. Last, either generate a

WEP key using the Passphrase or enter the WEP key manually.

WEP

. WEP is a basic encryption method, which is not as secure as WPA. To use WEP, select a Default Transmit Key

(choose which Key to use), and a level of WEP encryption,

64 bits 10 hex digits

or

128 bits 26 hex digits

. Then

either generate a WEP key using the Passphrase or enter the WEP key manually.

The Wireless Tab - Advanced Wireless Settings

Wireless-G Media Storage Link 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.

Advanced Wireless

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
