Chapter 9 Wireless LAN For example, if the wireless network has a RADIUS server, you can choose WPA or WPA2. If users do not log in to the wireless network, you can choose no encryption, Static WEP, WPA-PSK, or WPA2-PSK. Usually, you should set up the strongest encryption that every wireless client in the wireless network supports. For example, suppose the AP does not have a local user database, and you do not have a RADIUS server. Therefore, there is no user authentication. Suppose the wireless network has two wireless clients. Device A only supports WEP, and device B supports WEP and WPA. Therefore, you should set up Static WEP in the wireless network. Note: It is recommended that wireless networks use WPA-PSK, WPA, or stronger encryption. IEEE 802.1x and WEP encryption are better than none at all, but it is still possible for unauthorized devices to figure out the original information pretty quickly. Note: It is not possible to use WPA-PSK, WPA or stronger encryption with a local user database. In this case, it is better to set up stronger encryption with no authentication than to set up weaker encryption with the local user database. When you select WPA2-PSK in your EMG2306-R10A, you can also select an option (WPA Compatible) to support WPA as well. In this case, if some wireless clients support WPA and some support WPA2, you should set up WPA2-PSK (depending on the type of wireless network login) and select the WPA Compatible option in the EMG2306-R10A. Many types of encryption use a key to protect the information in the wireless network. The longer the key, the stronger the encryption. Every wireless client in the wireless network must have the same key. WPS WiFi Protected Setup (WPS) is an industry standard specification, defined by the WiFi Alliance. WPS allows you to quickly set up a wireless network with strong security, without having to configure security settings manually. Depending on the devices in your network, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (Personal Identification Number) in the devices. Then, they connect and set up a secure network by themselves. See how to set up a secure wireless network using WPS in the Section 7.2 on page 40. 9.4 General Wireless LAN Screen Use this screen to configure the SSID of the wireless LAN and configure the wireless security mode. The screen varies depending on what you select in the Security Mode field. Note: If you are configuring the EMG2306-R10A from a computer connected to the wireless LAN and you change the EMG2306-R10A's SSID, channel or security settings, you will lose your wireless connection when you press Apply to confirm. You must then change the wireless settings of your computer to match the EMG2306-R10A's new settings. EMG2306-R10A User's Guide 73

EMG2306-R10A User’s Guide

For example, if the wireless network has a RADIUS server, you can choose

WPA

WPA2

. If users

do not log in to the wireless network, you can choose no encryption,

Static WEP

WPA-PSK

, or

WPA2-PSK

Usually, you should set up the strongest encryption that every wireless client in the wireless

network supports. For example, suppose the AP does not have a local user database, and you do

not have a RADIUS server. Therefore, there is no user authentication. Suppose the wireless network

has two wireless clients. Device A only supports WEP, and device B supports WEP and WPA.

Therefore, you should set up

Static WEP

in the wireless network.

Note: It is recommended that wireless networks use

WPA-PSK

WPA

, or stronger

encryption. IEEE 802.1x and WEP encryption are better than none at all, but it is

still possible for unauthorized devices to figure out the original information pretty

quickly.

Note: It is not possible to use

WPA-PSK

WPA

or stronger encryption with a local user

database. In this case, it is better to set up stronger encryption with no

authentication than to set up weaker encryption with the local user database.

When you select

WPA2-PSK

in your EMG2306-R10A, you can also select an option (

WPA

Compatible

) to support WPA as well. In this case, if some wireless clients support WPA and some

support WPA2, you should set up

WPA2-PSK

(depending on the type of wireless network login)

and select the

WPA Compatible

option in the EMG2306-R10A.

Many types of encryption use a key to protect the information in the wireless network. The longer

the key, the stronger the encryption. Every wireless client in the wireless network must have the

same key.

WPS

WiFi Protected Setup (WPS) is an industry standard specification, defined by the WiFi Alliance. WPS

allows you to quickly set up a wireless network with strong security, without having to configure

security settings manually. Depending on the devices in your network, you can either press a

button (on the device itself, or in its configuration utility) or enter a PIN (Personal Identification

Number) in the devices. Then, they connect and set up a secure network by themselves. See how

to set up a secure wireless network using WPS in the

Section 7.2 on page 40

General Wireless LAN Screen

Use this screen to configure the SSID of the wireless LAN and configure the wireless security mode.

The screen varies depending on what you select in the

Security Mode

field.

Note: If you are configuring the EMG2306-R10A from a computer connected to the

wireless LAN and you change the EMG2306-R10A’s SSID, channel or security

settings, you will lose your wireless connection when you press

Apply

to confirm.

You must then change the wireless settings of your computer to match the

EMG2306-R10A’s new settings.
