DESCRIPTION

Wireless Set-

tings

SSID

Enter a name for your AP This name is broadcast to all wireless-capable

devices in range and can be used to connect to your AP.

You can enter up to 32 printable ASCII characters in this field.

Hide SSID

Select this option to keep your AP’s SSID private. Only users who

explicitly enter the SSID name in their connection window while con-

necting will be able to “see” it.

While effective at deterring the casual user from inadvertantly connect-

ing to your AP, it is the weakest of all wireless security. Anyone with a

basic sniffer program will be able to detect the channel.

Wireless

Mode

This displays a list of available wireless modes. As of this writing, the

N220 only supports 2.4 GHz.

Channel

Select a channel on which on broadcast your AP’s wireless signal.

If there are a high number of APs broadcast within range of one

another, try to use a channel that is either not in use or that has the

fewest number of broadcasters. Too many APs using the same channel

can interfere with one another.

Output

Power

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

notebook computers). This control changes the strength of the N220’s

antenna gain or transmission power. Antenna gain, listed here as a per-

centage, is the increase in coverage. Higher antenna gain improves the

range of the signal for better communications.

•

100%

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

the highest level of power consumption. If you are using the N220 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 consump-

tion.

•

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 wireless network to the specified wired network.

Note: This feature is not supported in Windows 2000.
