5.4.1

Security Settings

When you configure the NWD-270N to act as an AP and wireless security is activated, the

Configuration

screen varies according to the encryption method used by your network.

5.4.1.1

Disable

This option indicates that no security services are enabled. Anyone within range of your AP

can connect to it without having to enter a pre-shared key.

When security settings are disabled in

AP Mode

and if you have a shared

Internet connection via the

Bridge

feature (see

page 70

) or any shared folders

on the computer that is hosting the AP, they will be available to anyone who is

connected.

Output Power

Set this field if you need to conserve power consumption (especially for notebook

computers). This control changes the strength of the NWD-270N’s antenna gain or

transmission power. Antenna gain, listed here as a percentage, is the increase in

coverage. Higher antenna gain improves the range of the signal for better commu-

nications.

•

100%

- Sets the antenna gain at maximum output power. This has the highest

level of power consumption. If you are using the NWD-270N on a notebook

computer running on battery power, then using this power setting will drain the

battery the fastest.

•

75%

- Sets the antenna gain to medium-high output power. This is a decent

comprimise between signal strength and power consumption.

•

50%

- Sets the antenna gain to medium output power. The range is reduced

but the power consumption is much less.

•

25%

- Sets the antenna gain to low output power. This significantly reduces the

transmission range but save considerable power.

•

Lowest

- Sets the antenna gain to minimal output power. You are trading

decent transmission range for significant power savings.

Bridge

Select the check box and an Ethernet adapter (network interface card (NIC)) on

your computer from the drop-down list box. This allows you to connect your wire-

less network to the specified wired network.

Note: This feature is not supported in Windows 2000.

Security type

Select a security type for your AP. Options are

DISABLE

,

WEP

,

WPA-PSK

and

WPA2-PSK

.
