1.4 How to Set Up a Wireless LAN
This tutorial applies only to models that include wireless LAN.
You can configure different interfaces to use on the wireless LAN card. This lets you have different
wireless LAN networks using different SSIDs. You can configure the WLAN interfaces before or after
you install the wireless LAN card. This example shows how to create a WLAN interface that uses WPA
or WPA2 security and the USG’s local user database for authentication.
1.4.1 Set Up User Accounts
Besides WPA-PSK, the USG also supports TTLS using PAP so you can use the USG’s local user
database with WPA or WPA2 instead of needing an external RADIUS server. For each WLAN user, set
up a user account containing the user name and password the WLAN user needs to enter to connect
to the wireless LAN.
1 Click Configuration > Object > User/Group > User and the Add icon.
2 Set the User Name to wlan_user. Enter (and re-enter) the user’s password. Click OK.
3 Use the Add icon in the Configuration > Object > User/Group > User screen to set up the
remaining user accounts in similar fashion.
1.4.2 Create the WLAN Interface
1 Click Configuration > Network > Interface > WLAN > Add to open the WLAN Add screen.
2 Edit this screen as follows.
A (internal) name for the WLAN interface displays. You can modify it if you want to.
The USG’s security settings are configured by zones. Select to which security zone you want the WLAN
interface to belong (the WLAN zone in this example). This determines which security settings the USG
applies to the WLAN interface.
Configure the SSID (ZYXEL_WPA in this example).
If all of your wireless clients support WPA2, select WPA2-Enterprise as the Security Type,
otherwise select WPA/WPA-2-Enterprise. Set the Authentication Type to Auth Method. The
