Chapter 8 Wireless LAN
EMG1302-R10A User’s Guide
76
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 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 EMG1302-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 EMG1302-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 6.2 on page 41.
8.4 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 EMG1302-R10A from a computer connected to the
wireless LAN and you change the EMG1302-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
EMG1302-R10A’s new settings.
