Chapter 1 - Configuration
Connecting with a Wired Connection
The print server can be set up using a wired connection. Refer to the procedures below. The print server cannot use both
a wired and a wireless connection at the same time.
1 Connect the print server to an access point using an Ethernet cable.
2 Connect the AC adapter to the print server.
3 After it powers on, check the side of the print server.
Connecting to a Wireless Connection
There are three ways to connect the print server to a wireless connection: selecting the wireless access point from print
server’s Settings, WPS PIN method, or WPS push-button method. Refer to the procedures below.
The print server cannot use both a wired and a wireless connection at the same time. WPA2-PSK (TKIP) encryption is also
not supported.
Select Wireless Access Point from Settings
Once the print server is connected to a wired network, you can manually select the wireless access point to connect to
from the print server’s Settings. To open Settings, refer to the “Accessing Settings” section below.
Before starting, the print server’s connection method should be set to “Auto”. The access point should also have SSID
broadcast enabled and is not using WPA2-PSK (TKIP) encryption. Refer to Chapter 4 for more information.
1 Set up the print server on a wired connection then log in to Settings.
2 Navigate to Network - Wireless LAN.

6
3 Select a wireless access point; enter the encryption key and click Apply.
4 After saving, the print server reboots automatically.
5 Disconnect the Ethernet cable from the print server.
6 Disconnect the AC adapter from the print server; wait about 10 seconds and reconnect it.
7 Check the LEDs on the side of the print server.
Note: If the wireless LED is blinking, the connection could not be established. Check the access point and its
encryption key and try again.

7
Connect Using WPS PIN Method
You can use WPS to connect the print server wirelessly by registering the print server’s WPS PIN with your wireless
access point. The print server’s WPS PIN can be obtained from Settings. To open Settings, refer to the “Accessing Settings”
section below.
Before starting, the print server’s connection method should be set to “Auto”.
1 Set up the print server on a wired connection then log in to Settings.
2 Navigate to Network - Wireless LAN - WPS Settings and click Execute WPS.
3 Within 2 minutes, register the displayed PIN with the target access point.
4 Confirm that “WPS Success” is displayed from Settings. If the following window is not displayed, the connection
could not be established. Try again.
5 Disconnect the Ethernet cable from the print server.
6 Disconnect the AC adapter; wait about 10 seconds and reconnect it.

8
7 Wait about 30 seconds and check the LEDs on the side of the print server.
Note: If the wireless LED is blinking, the connection could not be established. Check the access point and its
encryption key and try again.
Connect Using WPS Push-Button Method
If your wireless access point has a WPS/AOSS button, you can use it to connect the print server wirelessly.
Before starting, the print server’s connection method should be set to “Auto”.
1 Connect the AC adapter to the print server. If the print server was using a wired connection, disconnect both the
Ethernet cable and the AC adapter from the print server and then re-connect the AC adapter only.
2 Wait for about 30 seconds, then press and hold the WPS button for about 5 seconds.
3 Press the access point’s WPS or AOSS button.
Note: If you are using Buffalo router, press and hold the AOSS button for at least two seconds to start WPS. This may
be different for other access point devices.

9
4 Wait about 30 seconds, then check the LEDs on the side of the print server.
Note: If the wireless LED is blinking, the connection could not be established. Try again from step 3.
Accessing Settings
Configuration of the print server is done from Settings, the web-based configuration GUI.
Note: Supported browsers include Internet Explorer 8 and later, Firefox 20 and later, and Safari 5 and later.

10
Access Using IP Address
If you know the IP address of the print server on your network, just type it in to the URL field of your browser and
press the enter key to open Settings. If you don’t know the print server’s IP address, refer to “Access from Network USB
Navigator” below.
1 Open a web browser.
2 Enter the print server’s IP address in the address field and press the enter key.
3 When the security window appears, enter “admin” for the username and “password” for the password, then click
OK.

11
Access from Network-USB Navigator
If Network-USB Navigator has been installed on your PC, you can use it to open Settings.
