Introduction

This quick start guide provides basic wireless configuration

information for the ProSafe UTM9S and UTM25S. For information

about advanced wireless features, and for complete configuration

steps, see the reference manual at downloadcenter.netgear.com.

Default Wireless Settings

The default wireless settings work well for most wireless networks,

but you need to configure the country of operation and wireless

security.

The country is initially set to the default country for the region where

the UTM is sold. You need to select the actual country of operation

from the country list. The countries in each region are listed in

alphabetic order.

These are the default settings:

•Asia. Azerbaijan

•Europe. Albania

•Middle East. Bahrain

•North America, Latin America, and The

Caribbean. United States

•Oceania. Australia

Item Description

Wireless Equipment Placement and Range

Guidelines

The range of your wireless connection can vary based on the location

of the UTM. The latency, data throughput performance, and notebook

power consumption of wireless adapters also vary depending on your

configuration choices.

Note: Failure to follow these guidelines can result in significant

performance degradation or the inability to connect wirelessly to the

UTM. For complete performance specifications, see the data sheet at

downloadcenter.netgear.com.

For best results, place your UTM according to the following general

guidelines:

•Near the center of the area in which your wireless devices

operate.

•In an elevated location such as a high shelf where the wirelessly

connected devices have line-of-sight access (even if through

walls).

•Away from sources of interference such as computers,

microwaves ovens, and 2.4 GHz cordless phones.

•Away from large metal surfaces or water.

•Placing the antennas in the upright position provides the best

horizontal coverage.

•If you are using multiple wireless access points such as the UTM,

it is better if access points use different radio frequency channels

to reduce interference. The recommended channel space

between adjacent access points is five channels (for example,

use Channels 1 and 6, or 6 and 11, or 1 and 11).

•The time that it takes to establish a wireless connection can vary

depending on both your security settings and placement. WEP

connections can take slightly longer to establish. Also, WEP

encryption can consume more battery power on a notebook

computer.

Configure the Country of Operation and

Operating Frequency

The region of operation is not configurable. It is set for the region in

which you purchased the UTM. The selection of the country is limited

to the countries in the region in which you purchased the UTM. As an

option, you can change the operating frequency from the default

setting of 2.4 GHz to 5 GHz.

To configure the country and frequency settings:

1. Select Network Config > Wireless Settings > Radio Settings.

The Radio Settings screen displays:

2. Select the country from the Country drop-down list.

3. (Optional) From the Operating Frequency drop-down list, select

5GHz to change the frequency from the default 2.4 GHz band to

the 5 GHz band.

Warning: When you change to the 5-GHz band, only 802.11na

devices can connect to the UTM. (In Greenfield mode, only 802.11n

devices can connect to the UTM.) 802.11b and 802.11g devices cannot

connect to the UTM.

4. Click Apply to save your settings. The wireless network module

(not the UTM9S or UTM25S) reboots.

Note: Other wireless settings that you can configure on the Radio

Settings screen are explained in “Configure the Basic Radio Settings”

in Appendix B, “Wireless Network Module for the UTM9S and

UTM25S,” of the reference manual.

Configure WPA+WPA2 with PSK Security

NETGEAR recommends that you configure wireless authentication

and encryption to secure your wireless traffic. WPA+WPA2 with a

pre-shared key (PSK) is easy to configure and works well in most

situations. However, if your network uses 802.11n devices only, select

WPA2 to enable the 802.11n devices to function at full speed.

To configure WPA+WPA2 with PSK security for the UTM9S or

UTM25S default wireless profile:

1. Select Network Config > Wireless Settings > Wireless

Profiles. The Wireless Profiles screen displays:

2. Click the Edit button in the Action column for the UTM9S or

UTM25S default wireless profile. The Edit Wireless Profiles screen

displays:

3. From the Security drop-down list, select WPA+WPA2.

The Encryption drop-down list automatically selects TKIP+AES,

which is the default encryption setting for WPA+WPA2.

4. From the Authentication drop-down list, select PSK.

5. In the WPA Password field, enter a password (also referred to as a

pre-shared key) of at least 8 characters.

Warning: If you use a wireless computer to configure the wireless

security settings, you are disconnected when you click Apply.

Reconfigure your wireless computer to match the new settings, or

access the UTM from a wired computer to make further changes.

6. Click Apply to save your settings.

Note: For other types of security (WEP, WPA, WPA2, and RADIUS

authentication) and for the other wireless profile settings, see

“Wireless Security Profiles” in Appendix B, “Wireless Network Module

for the UTM9S and UTM25S,” of the reference manual.

Test Wireless Connectivity

After you have configured the UTM as explained in the previous

sections, test your wireless clients for wireless connectivity before

you place the UTM at its permanent position.

To test for wireless connectivity:

1. Configure the 802.11 wireless clients so that they all have the

same SSID that you have configured on the UTM, for example,

netgear-1 (the default SSID). Make sure that the wireless mode

on the UTM supports the wireless capacity of the wireless

clients.

2. Verify that your wireless clients have a link to the UTM.

3. Verify network connectivity by using a browser such as Internet

Explorer 7.0 or later or Mozilla Firefox 4.0 or later to browse the

Internet, or check for file and printer access on your network.

If you have trouble connecting to the module, try to connect without

security by selecting OPEN from the Security drop-down list on the

Edit Wireless Profiles screen for the profile that you are using (see

the figure on page 9).
