function. In the following example we will explain the use of WPS with the combination

Right click the green ‘R’ or the red ‘R’ if there is no connection. 

2. 

Select ‘Use RaConfig as Configuration Utility’. 

3. 

Right click the green or red ‘R’ once more and choose ‘Launch Config Utility’. 

4. 

The software program ‘RaUI’ will be displayed. 

5. 

Click ‘WPS’. 

6. 

Press the reset/wps button on the back of the wireless router for about 1 second. 

7. 

The WLAN led goes out. This is normal. 

8. 

Now press the WPS button on the EM4554 for about 3 seconds. 

9. 

The EM4554 will search for the wireless router’s signal. 

10.  The wireless router and the EM4554 will ‘agree’ to use an encrypted key. The 

moment this process is done you will see the notification ‘Get WPS profile 
successful’. 

11.  The WLAN led will light up again. 
12.  Congratulations! You have now secured your network and you can use the 

internet wirelessly.

other wireless receiver with WPS support. 

8.0 Frequently asked questions 

Q

:  Can I increase the range of my wireless network adapter? 

A

For wireless devices the rule is that at a lower speed a greater distance can be 
bridged. By default your wireless card is set to a higher speed. If the distance 
between your wireless card and your router is rather large, you might want to 
consider setting the wireless card to a lower speed of 54 Mbps (802.11G) or 11 
Mbps (802.11B). The lower speed allows the signal to travel a greater distance 
but also limits the maximum speed of your connection. Follow these steps:  
1. 

Open the Ralink utility  

2. 

Click the ‘Advanced’ button.    

3. 

Select ‘802.11 B/G’ or “802.11 B’.  

4. 

Click ‘Apply’ to save the settings. 

 

Q: 

The EM4554 is a wireless N receiver. Can I use this adapter on a wireless  router 
which only supports the wireless ‘B’ or ‘G’ standards? 

A:  

The EM4554 is specially designed for use with a 300 N router. However, the 
EM4554 will work without any problems when using the older ‘B’ or ‘G’ standards.
