Introducing the NWA

This chapter introduces the main applications and features of the NWA. It also discusses the ways you can manage your NWA.

1.1 Introducing the NWA

This User’s Guide covers the following models: NWA1121-NI, NWA1123-NI and NWA1123-AC. Your NWA is an IPv6 wireless AP (Access Point) that can function in several wireless modes. It extends the range of your existing wired network without additional wiring, providing easy network access to mobile users.

The NWA controls network access with MAC address filtering and RADIUS server authentication. It also provides a high level of network traffic security, supporting IEEE 802.1x, Wi-Fi Protected Access (WPA), WPA2 and WEP data encryption. Its Quality of Service (QoS) features allow you to prioritize time-sensitive or highly important applications such as VoIP.

Your NWA is easy to install, configure and use. The embedded Web-based configurator enables simple, straightforward management and maintenance.

See the Quick Start Guide for instructions on how to make hardware connections.

1.1.1 Dual-Band

The NWA1123-NI or NWA1123-AC is a dual-band AP and able to function both 2.4G and 5G networks at the same time. You could use the 2.4 GHz band for regular Internet surfing and

NWA1120 Series User’s Guide

10

Chapter 1 Introducing the NWA

downloading while using the 5 GHz band for time sensitive traffic like high-definition video, music, and gaming.

Figure 1 Dual-Band Application

1.2 Wireless Modes

The NWA can be configured to use the following WLAN operating modes:

	OPERATING MODE	NUMBER OF	REPEATER FUNCTION	AP FUNCTION
		SUPPORTED SSID
	MBSSID	8	No	Yes
	Client	1	No	No
	Root AP	5	Yes	Yes
	Repeater	1	Yes	Yes

Applications for each operating mode are shown below.

1.2.1 MBSSID

A Basic Service Set (BSS) is the set of devices forming a single wireless network (usually an access point and one or more wireless clients). The Service Set IDentifier (SSID) is the name of a BSS. In Multiple BSS (MBSSID) mode, the NWA provides multiple virtual APs, each forming its own BSS and using its own individual SSID profile.

You can configure multiple SSID profiles, and have all of them active at any one time.

You can assign different wireless and security settings to each SSID profile. This allows you to compartmentalize groups of users, set varying access privileges, and prioritize network traffic to and from certain BSSs.

NWA1120 Series User’s Guide

11

Chapter 1 Introducing the NWA

To the wireless clients in the network, each SSID appears to be a different access point. As in any wireless network, clients can associate only with the SSIDs for which they have the correct security settings.

For example, you might want to set up a wireless network in your office where Internet telephony (VoIP) users have priority. You also want a regular wireless network for standard users, as well as a ‘guest’ wireless network for visitors. In the following figure, VoIP_SSID users have QoS priority, SSID01 is the wireless network for standard users, and Guest_SSID is the wireless network for guest users. In this example, the guest user is forbidden access to the wired Land Area Network (LAN) behind the AP and can access only the Internet.

Figure 2 Multiple BSSs

1.2.2 Wireless Client

The NWA can be used as a wireless client to communicate with an existing network.

Note: The NWA1123-NI or NWA1123-AC is a dual-band AP which contains two different types of wireless radios to transmit at 2.4 GHz and 5 GHz bands separately and simultaneously. If one of the NWA1123-NI wireless radio is set to work in client mode, the other radio will be disabled automatically.

12

NWA1120 Series User’s Guide

Chapter 1 Introducing the NWA

In the figure below, the printer can receive requests from the wired computer clients A and B via the NWA in Client mode (Z) using only the 2.4 GHz band.

Figure 3 Wireless Client Application

NWA1120 Series User’s Guide

13

Chapter 1 Introducing the NWA

1.2.3 Root AP

In Root AP mode, the NWA (Z) can act as the root AP in a wireless network and also allow repeaters (X and Y) to extend the range of its wireless network at the same time. In the figure below, both clients A, B and C can access the wired network through the root AP.

Figure 4 Root AP Application

On the NWA in Root AP mode, you can have multiple SSIDs active for reqular wireless connections and one SSID for the connection with a repeater (repeater SSID). Wireless clients can use either SSID to associate with the NWA in Root AP mode. A repeater must use the repeater SSID to connect to the NWA in Root AP mode.

When the NWA is in Root AP mode, repeater security between the NWA and other repeater is independent of the security between the wireless clients and the AP or repeater. If you do not enable repeater security, traffic between APs is not encrypted. When repeater security is enabled, both APs and repeaters must use the same pre-shared key. See Section 6.6 on page 73 for more details.

Unless specified, the term “security settings” refers to the traffic between the wireless clients and the AP. At the time of writing, repeater security is compatible with the NWA only.

1.2.4 Repeater

14

The NWA can act as a wireless network repeater to extend a root AP’s wireless network range, and also establish wireless connections with wireless clients.

Using Repeater mode, your NWA can extend the range of the WLAN. In the figure below, the NWA in Repeater mode (Z) has a wireless connection to the NWA in Root AP mode (X) which is connected to a wired network and also has a wireless connection to another NWA in Repeater mode (Y) at the same time. Z and Y act as repeaters that forward traffic between associated wireless

NWA1120 Series User’s Guide

Chapter 1 Introducing the NWA

clients and the wired LAN. Clients A and B access the AP and the wired network behind the AP throught repeaters Z and Y.

Figure 5 Repeater Application

When the NWA is in Repeater mode, repeater security between the NWA and other repeater is independent of the security between the wireless clients and the AP or repeater. If you do not enable repeater security, traffic between APs is not encrypted. When repeater security is enabled, both APs and repeaters must use the same pre-shared key. See Section 6.6 on page 73 for more details.

Once the security settings of peer sides match one another, the connection between devices is made.

At the time of writing, repeater security is compatible with the NWA only.

1.3 Ways to Manage the NWA

Use any of the following methods to manage the NWA.

•Web Configurator. This is recommended for everyday management of the NWA using a (supported) web browser.

•FTP (File Transfer Protocol) for firmware upgrades and configuration backup and restore.

•SNMP (Simple Network Management Protocol). The device can be monitored by an SNMP manager.

NWA1120 Series User’s Guide

Chapter 1 Introducing the NWA

1.4 Configuring Your NWA’s Security Features

Your NWA comes with a variety of security features. This section summarizes these features and provides links to sections in the User’s Guide to configure security settings on your NWA. Follow the suggestions below to improve security on your NWA and network.

1.4.1 Control Access to Your Device

Ensure only people with permission can access your NWA.

•Control physical access by locating devices in secure areas, such as locked rooms. Most NWAs have a reset button. If an unauthorized person has access to the reset button, they can then reset the device’s password to its default password, log in and reconfigure its settings.

•Change any default passwords on the NWA, such as the password used for accessing the NWA’s web configurator (if it has a web configurator). Use a password with a combination of letters and numbers and change your password regularly. Write down the password and put it in a safe place.

•See Section 11.5 on page 113 for instructions on changing your password.

•Configure remote management to control who can manage your NWA. See Chapter 9 on page 94 for more information. If you enable remote management, ensure you have enabled remote management only on the IP addresses, services or interfaces you intended and that other remote management settings are disabled.

1.4.2Wireless Security

Wireless devices are especially vulnerable to attack. Take the following measures to improve wireless security.

•Enable wireless security on your NWA. Choose the most secure encryption method that all devices on your network support. See Section 6.6 on page 73 for directions on configuring encryption. If you have a RADIUS server, enable IEEE 802.1x or WPA(2) user identification on your network so users must log in. This method is more common in business environments.

•Hide your wireless network name (SSID). The SSID can be regularly broadcast and unauthorized users may use this information to access your network. See Section 6.5 on page 71 for directions on using the web configurator to hide the SSID.

•Enable the MAC filter to allow only trusted users to access your wireless network or deny unwanted users access based on their MAC address. See Section 6.9 on page 83 for directions on configuring the MAC filter.

1.5Good Habits for Managing the NWA

Do the following things regularly to make the NWA more secure and to manage it more effectively.

•Change the password. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters.

•Write down the password and put it in a safe place.

16

NWA1120 Series User’s Guide

Chapter 1 Introducing the NWA

•Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the NWA to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the NWA. You could simply restore your last configuration.

1.6Hardware Connections

See your Quick Start Guide for information on making hardware connections.

Chapter 2 Introducing the Web Configurator

2.3 Resetting the NWA

If you forget your password or cannot access the web configurator, you will need to use the RESET button at the rear panel of the NWA. This replaces the current configuration file with the factorydefault configuration file. This means that you will lose all the settings you previously configured. The password will be reset to “1234”.

Figure 9 The RESET Button

2.3.1 Methods of Restoring Factory-Defaults

You can erase the current configuration and restore factory defaults in two ways:

Use the RESET button to upload the default configuration file. Hold this button in for about 3 seconds (the light will begin to blink). Use this method for cases when the password or IP address of the NWA is not known.

Use the web configurator to restore defaults (refer to Section 11.8 on page 116).

Tutorial

This chapter first provides an overview of how to configure the wireless LAN on your NWA, and then gives step-by-step guidelines showing how to configure your NWA for some example scenarios.

4.1 How to Configure the Wireless LAN

This section illustrates how to choose which wireless operating mode to use on the NWA and how to set up the wireless LAN in each wireless mode. See Section 4.1.2 on page 28 for links to more information on each step.

4.1.1Choosing the Wireless Mode

•Use MBSSID (Multiple Basic Service Set Identifier) operating mode if you want to use the NWA as an access point with some groups of users having different security or QoS settings from other groups of users. See Section 1.2.1 on page 11 for details.

•Use Client operating mode if you want to use the NWA to access a wireless network. See Section 1.2.2 on page 12 for details.

•Use Root AP operating mode if you want to allow wireless clients to access your wired network through the NWA and also have repeaters communicate with the NWA to expand wireleass coverage. See Section 1.2.3 on page 14 for details.

•Use Repeater operating mode if you want to use the NWA to communicate with the root AP or other repeaters. See Section 1.2.4 on page 14 for details.

4.1.2Further Reading

Use these links to find more information on the steps:

•Choosing 802.11 Mode: see Section 6.4 on page 57.

•Choosing a wireless Channel ID: see Section 6.4 on page 57.

•Choosing a Security mode: see Section 6.6 on page 73.

•Configuring an external RADIUS server: see Section 6.7 on page 79.

•Configuring MAC Filtering: see Section 6.9 on page 83.

4.2How to Configure Multiple Wireless Networks

In this example, you have been using your NWA as an access point for your office network. Now your network is expanding and you want to make use of the MBSSID feature (see Section 6.4.4 on

NWA1120 Series User’s Guide

28

Chapter 4 Tutorial

page 68) to provide multiple wireless networks. Each wireless network will cater to a different type of user.

You want to make three wireless networks: one standard office wireless network with all the same settings you already have, another wireless network with high priority QoS settings for Voice over IP (VoIP) users, and a guest network that allows visitors to access only the Internet and the network printer.

To do this, you will take the following steps:

1Edit the SSID profiles.

2Change the operating mode from Root AP to MBSSID and reactivate the standard network.

3Configure different security modes for the networks.

4Configure a wireless network for standard office use.

5Configure a wireless network for VoIP users.

6Configure a wireless network for guests to your office.

The following figure shows the multiple networks you want to set up. Your NWA is marked Z, the main network router is marked A, and your network printer is marked B.

B

A

Z

The standard network (SSID01) has access to all resources. The VoIP network (VoIP_SSID) has access to all resources and a high QoS priority. The guest network (Guest_SSID) has access to the Internet and the network printer only, and a low QoS priority.

Chapter 4 Tutorial

To configure these settings, you need to know the Media Access Control (MAC) addresses of the devices you want to allow users of the guest network to access. The following table shows the addresses used in this example.

Table 5 Tutorial: Example Information

Network router (A) MAC address	00:AA:00:AA:00:AA
Network printer (B) MAC address	AA:00:AA:00:AA:00

4.2.1Configure the SSID Profiles

1Log in to the NWA (see Section 2.2 on page 18). Click Wireless LAN > SSID. The SSID screen appears.

2Click the Edit icon next to the Profile1.

3 Rename the Profile Name and SSID as SSID01. Click Apply.

4 Repeat Step 2 and 3 to change Profile2 and Profile3 to VoIP_SSID and Guest_SSID.
