• PA = Powerline Adapter
• APN = Your existing wireless router or AP wireless Network
• PL = Powerline connection
Using a PE is desirable when you want to expand your existing wireless network, there is a power
connnection to it, and the PE is located beyond the Wi-Fi range of the AP, or there are obstructions,
such as thick walls, impeding Wi-Fi signals between them.
These are some ways to configure the PLA4231 for Wi-Fi access in the PE location.
• Use the default PLA4231 wireless settings (SSID = ZyXEL, no Wi-Fi key). No configuration is
necessary, but the PLA4231 wireless network is open (no Wi-Fi key) and vulnerable.
• Copy the AP settings to the PLA4231 using the WPS button. When using WPS to copy wireless
settings, the PLA4213 must be within 5 meters of the AP. After a successful copy, position them
where you want them in your Powerline network. This allows seamless wireless roaming between
APN and PEN networks but some wireless clients may have problems if they discover duplicate
SSIDs. You also won’t know if your wireless device is connecting to the APN or the PEN.
• Use the web configurator to configure a different SSID and Wi-Fi key on the PLA4231 (SSID-2,
Wi-Fi Key-2). Roaming is not seamless as you need to manually connect to the PEN when the
signal from the APN becomes weak (and vice-versa).

10.2 What You Can Do
•Use the General screen (Section 10.4 on page 70) to turn the wireless connection on or off,
enter the SSID, select the channel, and configure wireless security between the PLA4231 and the
wireless clients.
•Use the MAC Filter screen (Section 10.6 on page 76) to allow or deny wireless stations based on
their MAC addresses from connecting to the PLA4231.
•Use the Advanced screen (Section 10.7 on page 78) to configure wireless advanced features,
such as set the RTS/CTS Threshold and HT physical mode.
•Use the QoS screen (Section 10.8 on page 78) to enable Wifi MultiMedia Quality of Service
(WMMQoS). This allows the PLA4231 to automatically set priority levels to services, such as e-
mail, VoIP, chat, and so on.
•Use the WPS screen (Section 10.9 on page 79) to quickly set up a wireless network with strong
security, without having to configure security settings manually.
•Use the WPS Station screen (Section 10.10 on page 81) to add a wireless station using WPS.
