Chapter 5 ZyXEL Utility - AP Mode

NWD-211AN User’s Guide

Wireless

Mode

Select the wireless networking protocol used by your AP. Supported

protocols are:

• A - Supports an operational frequency of 5 GHz.

• B - Supports an operational frequency of 2.41 GHz and dynamically

shifts up to 11 Mbps network speed.

• B/G - Supports an operational frequency of 2.4 GHz and

dynamically shifts up to 54 Mbps network speed.

• B/G/N - Supports an operational frequency of 2.4 GHz, dynamically

shifts up to 300 Mbps network speed, and supports significantly

boosted throughput.

• A/B/G/N - Supports an operational frequency of 5 GHz and 2 GHz,

dynamically shifts up to 300 Mbps network speed, and supports

significantly boosted throughput.

When selecting a wireless mode, try to choose one that matches the

mode of all the connecting computers. For example, if you know that

five different computers will be connecting to your AP and they all are

using the A protocol, set your AP to broadcast in the same mode to

reduce the likelihood of transmission interference.

If you are not certain which mode to use, select the A/B/G/N mode to

ensure maximum compatibility with all potential incoming connections.

Note: This option is not available in Windows Vista.

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 NWD-

211AN’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 communications.

• 100% - Sets the antenna gain at maximum output power. This has

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

211AN 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 wireless network to the specified wired network.

Note: This feature is not supported in Windows 2000.
