Setting up a Wi-Fi connection 

Note:

 

Before setting up a Wi-Fi connection, ensure that a wireless network adapter 

has been installed on your computer. If the wireless network adapter is 

functioning correctly, you will be able to find a wireless network connection in 

your computer's connection manager application. 

Method 1: Set up a Wi-Fi connection. 

Step 1 

Ensure that 

  is steady on. 

Step 2 

Scan for available wireless network connections using your computer's 

connection manager application. 

Step 3 

Connect to the wireless network that has the same service set 

identification (SSID) as the device. 

Note:

 

 

If a security mechanism has been enabled for the wireless network 

connection, enter the correct Wi-Fi key. 

 

The SSID and the Wi-Fi key are printed on the device label. 

 

To protect your wireless network from unauthorized access, change the 

SSID and Wi-Fi key a regular intervals. For details, see the help information 

on the web management page. 

Method 2: Set up a WPS connection. 

If the client to which your device connects supports WPS, a Wi-Fi key is generated 

automatically. For details about the client's operations, see its user guide. 
To set up a WPS connection: 

Step 1 

Ensure that 

  is steady on. 

Step 2 

Press and hold 

  until 

  blinks to activate the WPS 

connection on your device. 

Step 3 

Activate the WPS connection on the client.
