PLA4231 User’s Guide 9CHAPTER 1Introducing the PLA42311.1 OverviewThis chapter introduces the main applications and features of the PLA4231 HomePlug AV compliant powerline adapter. In this User’s Guide the electrical wiring network is referred to as the “powerline network”. The HomePlug AV standard specifies how network devices communicate using standard electrical wiring. 1.2 Expand Your Network with the PLA4231The PLA4231 plugs into an ordinary power outlet to easily extend a cable or DSL broadband connection or existing Ethernet (LAN) network to any other electrical outlet in any room of a house, all without the need for any new cabling. Devices can securely communicate with each other at high data transfer rates. The PLA4231 uses 128-bit Advanced Encryption Standard (AES) to ensure safe transfer of information. Figure 1 Expand Your Network with the PLA4231Connect your PLA4231 to an Internet gateway such as a modem and plug it into an ordinary power outlet in your home. Plug a second PLA4231 into another power outlet and connect a computer to the PLA4231 for Internet access. You can also connect a computer to your existing wireless network through the PLA4231 which acts as an AP or wireless extender. Your network can be further
Chapter 1 Introducing the PLA4231PLA4231 User’s Guide10expanded by plugging additional PLA4231s into other outlets in your home and connecting other computers or network devices (for example, a printer) to them. Refer to your Quick Start Guide for hardware connection information. 1.3 Ways to Manage the PLA4231•Use the RESET/ENCRYPT button to add powerline devices to your powerline network if they have this button. See Chapter 3 on page 15 for instructions on using the ENCRYPT feature.•Use the PLA42xx Series Configuration Utility (or utility, for short) to manage the PLA4231. See Chapter 4 on page 23 for instructions on installing the utility.Note: This User’s Guide describes the latest version utility. This utility is only compatible with a PLA4231 which has the latest firmware installed. If you don’t already have them, download the latest firmware and utility from the ZyXEL website.• Use the Web Configurator for everyday management of the PLA4231 using a (supported) web browser. See Section 7.2 on page 49 for instructions on accessing the Web Configurator.• WPS (Wi-Fi Protected Setup) button. You can use the WPS button or the WPS section of the Web Configurator to set up a wireless network with your PLA4231. See Section on page 13 for instructions on using the WPS button.1.4 Good Habits for Managing the PLA4231Do the following things regularly to make the PLA4231 more secure and to manage the PLA4231 more effectively.• Change the password. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters.• Write down the password and put it in a safe place.• Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the PLA4231 to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the PLA4231. You could simply restore your last configuration.1.5 Powerline SecuritySince your powerline network may extend outside your premises, it is important to set up security on your PLA4231.
Chapter 1 Introducing the PLA4231PLA4231 User’s Guide 111.5.1 Powerline PasswordsYou use two types of passwords in the HomePlug AV powerline network. The following table describes the differences between the passwords.1.5.2 Setting Up Powerline SecurityThe ENCRYPT feature automatically sets up security on your powerline network. Use this feature if your powerline devices have the RESET/ENCRYPT button. If your devices do not have the RESET/ENCRYPT button, use the PLA42xx Series Configuration Utility to set up security on the PLA4231. Although the PLA4231 is a “plug-and-play” network expanding solution there are several reasons for enabling security on the powerline network in your home.1It’s easy and only requires you to change a network name.2It’s a good idea to ensure privacy of your communication. When you use the PLA4231 and other powerline adapters, the electrical wiring in your home becomes an extension of your Ethernet network. Your network traffic flows freely within the electrical circuit of your home and is bounded in most cases by a power meter. Without security (encryption) your information is accessible to anyone using a powerline adapter on the same electrical circuit. In some cases, a circuit can be shared by more than one household.To prevent compromising your network security, you can create a private network. A private network uses a secret password (Network Name) to make sure that only permitted powerline adapters can communicate in your network. See Section 5.3 on page 29 for information on setting up a private network.3You may need to change the Network Name to create multiple powerline networks. See the next section for more information on how to set up a multiple network.Table 1 Powerline Password SummaryPASSWORD DESCRIPTIONNetwork Name All powerline adapters that follow the HomePlug AV standard are shipped with the same powerline network name “HomePlugAV”. Change the network name via the PLA42xx Series Configuration Utility to create a private network. See Section 5.3 on page 29.DAK (Data Access Key) PasswordIn order to manage the powerline adapters on your powerline network you must enter the adapters’ DAK password in the PLA42xx Series Configuration Utility. This password is printed on the powerline adapter itself. You don’t need to add the password for the powerline adapter directly connected to the computer running the configuration utility (local powerline adapter), you only have to add the remote powerline adapters’ passwords (those on your circuit, but not directly connected to your computer).
Chapter 1 Introducing the PLA4231PLA4231 User’s Guide121.6 Multiple NetworksMultiple powerline networks can coexist on a single powerline circuit. You might want to implement multiple powerline networks in a small office environment where you have two separate Ethernet networks. 1Connect one powerline adapter to a router or switch on the first Ethernet network and assign a Network Name (for example “Password1”) to this powerline adapter. Add additional powerline adapters to your network by plugging them into your powerline outlets and assigning them “Password1”. This completes the configuration of your first powerline network.2Connect another powerline adapter to a router or switch on the second Ethernet network and assign a different Network Name (for example “Password2”) to this powerline adapter. Again, add additional powerline adapters and assign them “Password2”.You now have two private networks on your powerline circuit. Information is not shared between the two networks as only powerline adapters with the same Network Name can communicate with each other.1.7 Resetting the PLA4231If you forget your password or IP address, or you cannot access the Web Configurator, you will need to use the RESET/ENCRYPT button at the side of the PLA4231 to reload the factory-default configuration file. This means that you will lose all configurations that you had previously saved, the password will be reset to “1234” and the IP address will be reset to “192.168.1.2”.1.7.1 Procedure to Use the Reset Button1Make sure the power LED is on.2Press the RESET button for 10 to 15 seconds (until the power LED begins to blink) and release it to set the PLA4231 back to its factory-default configurations.
PLA4231 User’s Guide 13CHAPTER 2The WPS Button2.1 WPS OverviewYour PLA4231 supports Wi-Fi Protected Setup (WPS), which is an easy way to set up a secure wireless network. WPS is an industry standard specification, defined by the Wi-Fi Alliance.WPS allows you to quickly set up a wireless network with strong security, without having to configure security settings manually. Each WPS connection works between two devices. Both devices must support WPS (check each device’s documentation to make sure). Depending on the devices you have, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (a unique Personal Identification Number that allows one device to authenticate the other) in each of the two devices. When WPS is activated on a device, it has two minutes to find another device that also has WPS activated. Then, the two devices connect and set up a secure network by themselves.2.2 How to Use the WPS ButtonYou can use the WPS button on the side panel of the PLA4231 to activate WPS.1Make sure the power LED and the WLAN LED are on (not blinking).2To copy wireless settings (SSID and wireless security key for example) from an access point (AP) or wireless router, press the WPS button for longer than five seconds and release it. The WLAN LED begins to blink.To connect a WPS-enabled wireless client (such as your computer with a WPS-enabled wireless adapter) to the PLA4231 via Wi-Fi or to the existing wireless network through the PLA4231, press the WPS button for two or three seconds and release it. The WLAN LED begins to blink.3Press the WPS button on another WPS-enabled device within range of the PLA4231. 4The WLAN LED turns steady on when WPS was successful. The WLAN LED will be off for about ten seconds if WPS has failed, and comes on again. Note: You must activate WPS in the PLA4231 and in another wireless device within two minutes of each other.
Chapter 2 The WPS ButtonPLA4231 User’s Guide14
PLA4231 User’s Guide 15CHAPTER 3The RESET/ENCRYPT ButtonUse the RESET/ENCRYPT button to automatically set up a secure powerline connection between your powerline devices.3.1 RESET/ENCRYPT Button OverviewThe RESET/ENCRYPT button allows you to set up a secure powerline connection with other HomePlug AV compliant powerline devices which also support the ENCRYPT feature. No other powerline setting changes are required to connect. You can use the RESET/ENCRYPT button to:• set up a new powerline network.• separate an existing powerline network into multiple networks.• reset the PLA4231 to the factory defaults.3.2 Set Up a HomePlug AV Network with ENCRYPTYou can connect a number of devices on a powerline network, but you can use the RESET/ENCRYPT button on only two devices at a time. Place a powerline device close to another powerline device so you have time to set up each one. After you set up the first powerline device, you have 120 seconds to set up the second powerline device. You can disconnect them from your computer or modem (or other networking equipment) if you need to move them close to each other, but the powerline devices need to be plugged into power outlets.Follow the steps below to set up your HomePlug AV Network:1Press and hold the RESET/ENCRYPT button at the side of your powerline device for 5 to 8 seconds and then release it. This resets the network name to a random value and removes your device from any network it may belong to.
Chapter 3 The RESET/ENCRYPT ButtonPLA4231 User’s Guide162Press the RESET/ENCRYPT button at the side of your powerline device for 0.5 to 3 seconds. The power ( ) light will blink as the powerline device tries to set up a connection.Figure 2 ENCRYPT Connection Procedure Note: The RESET/ENCRYPT button’s location varies for each Powerline model.3Repeat step 2 in this section for the other powerline device you wish to connect. This must be done within 120 seconds of pressing the RESET/ENCRYPT button on the PLA4231.Note: Check the lights on the two powerline devices. The power ( ) and HomePlug ( ) lights should be blinking while the devices are connecting. Several times all lights blink simultaneously and the HomePlug ( ) light also shows red. Wait for about one minute while your powerline devices connect. If the power ( ) light does not blink when you press RESET/ENCRYPT, you have probably pressed the RESET/ENCRYPT button for too long. Try again, pressing the RESET/ENCRYPT button for 0.5 to 3 seconds. If the HomePlug ( ) lights on both powerline devices do not light up, the powerline devices are not connected. Repeat steps 2 and 3 in this section. If that doesn’t work, see the Troubleshooting in Section 14.5 on page 99 for suggestions. 4To add more powerline devices to your network, press and hold the RESET/ENCRYPT button on device C (shown below) for for 5 to 8 seconds and then release it. press 0.5 ~ 3 seconds press 0.5 ~ 3 seconds within 2 minutes
Chapter 3 The RESET/ENCRYPT ButtonPLA4231 User’s Guide 175Then repeat steps 2 and 3 in this section using any powerline device (A or B) you have connected using ENCRYPT and the powerline device you want to connect (C). You must use the RESET/ENCRYPT button on both devices.Figure 3 Adding More Powerline Adapters to Your Network 6If you disconnected your computer or modem (or any other networking product connected to your powerline device) in step of this section, you can now reconnect them.This sets up your powerline network between your powerline devices. 3.3 Setting Up Multiple NetworksYou can use the RESET/ENCRYPT button to set up multiple powerline networks using your existing powerline network. ABORCAB
Chapter 3 The RESET/ENCRYPT ButtonPLA4231 User’s Guide18For example, you have already set up a powerline network in your home (A) which accesses a printer (B). Now you want a separate powerline network connection from your laptop to your printer (C).Figure 4 One Existing Powerline Network 1Click the RESET/ENCRYPT button on (A) for 5 to 8 seconds and then release it. This disconnects (A) from (B). 2Click the RESET/ENCRYPT button on (A) and (C) for 0.5 to 3 seconds and within two minutes of each other.3Wait for about one minute while (A) and (C) connect.4Check the LEDs on both (A) and (C). When the power ( ) and HomePlug ( ) lights stop blinking and the power ( ) light shines steadily, the devices are connected. Figure 5 Two Separate Powerline Networks ACBACB
Chapter 3 The RESET/ENCRYPT ButtonPLA4231 User’s Guide 19Congratulations. You now have two separate powerline networks as shown above.If the HomePlug ( ) lights on both powerline devices do not light up, the powerline devices are not connected. Repeat the connection process, making certain you press the RESET/ENCRYPT buttons for the correct time and within two minutes of each other. If that does not work see Section 14.5 on page 99 for suggestions.3.4 RESET/ENCRYPT Button BehaviorThe following table summarizes the actions that occur when the RESET/ENCRYPT button is pressed for specific lengths of time. See Troubleshooting in Chapter 14 on page 99 for suggestions on problems with the RESET/ENCRYPT button and the lights.

PLA4231 User’s Guide 27CHAPTER 5Using the Powerline Configuration Utility5.1 OverviewThis chapter shows you how to use the Configuration Utility (or Utility) to secure, manage and set up Quality of Service (QoS) on your powerline network.The PLA4231 is designed as a plug-and-play network expanding solution. This means that once you complete your hardware connections, the PLA4231s in your network (without additional configuration) are able to communicate with each other by sending and receiving information over your home’s electrical wiring (A).Figure 11 Example Network SetupAll HomePlug AV compliant powerline adapters within range can join your network. The range varies depending on the quality of your home’s wiring.Note: See Section 5.1.1 on page 27 for more information on enhancing your powerline network security.5.1.1 Powerline Network Security When the PLA4231s communicate with each other, they use encryption to protect the information that is sent in the powerline network. Encryption is like a secret code. If you do not know the secret code, you cannot understand the message. The HomePlug AV standard uses 128-bit AES (Advanced Encryption Standard) to safely transmit data between powerline adapters.For the powerline adapters to communicate with each other they all need to use the same network name. This network name allows the powerline adapters to understand the encrypted information sent in the powerline network. A
Chapter 5 Using the Powerline Configuration UtilityPLA4231 User’s Guide28By default the PLA4231s are all configured with the network name HomePlugAV, this allows you to simply plug the devices in and not worry about setting up security. If you want to enhance the security on your powerline network, you can change the network name on the powerline adapters you want to allow to communicate in your powerline network.5.1.2 Device Access Key (DAK)In order to manage the powerline adapters on your powerline network you must enter the adapters’ password in the PLA42xx Series Configuration Utility. This password is called the DAK (Device Access Key) password. This password is printed on the powerline adapter itself. You don’t need to enter the DAK password for the powerline adapter directly connected to the computer running the utility (local powerline adapter), you only have to add the remote powerline adapters’ passwords (those in your powerline network, but not directly connected to your computer).5.2 Starting the Configuration UtilityTo launch the PLA42xx Series Configuration Utility simply double click on the configuration icon on your desktop.Figure 12 PLA42xx Series Configuration Utility IconAlternatively, start the utility by browsing to it from the start menu. Click Start > Programs > ZyXEL PLA42xx Series Configuration > PLA42xx Series Configuration.
Chapter 5 Using the Powerline Configuration UtilityPLA4231 User’s Guide 295.3 Configuration Screen Use the Configuration screen to see which devices are recognized by your powerline network, to configure your PLA4231 and to set up a secure powerline network by changing the powerline network name. This screen opens up when you launch the utility.Figure 13 Configuration ScreenThe following table describes the labels in this screen. Table 3 Configuration ScreenLABEL DESCRIPTIONNetwork TopologyUse this to select which powerline network information is displayed. Different powerline networks are identified by the Ethernet interface (network card) on your computer which is connected directly to a powerline adapter. Typically there is only one connection. However, if your computer has two network cards and both are connected to a powerline adapter, then you have two powerline networks.The fields described below are used to identify the powerline adapters recognized on the powerline network. The configuration utility automatically updates this information every 10 seconds. Click Scan to refresh the information in these fields (immediately).Note: Only devices which share the same network name are displayed in this table.Site This field displays•Local, if it is identifying the powerline adapter directly connected to the computer running the configuration utility.•Remote, if it is a powerline adapter in your powerline network but not directly connected to the computer running the configuration utility.MAC Address This is a read-only field which shows the MAC address of the powerline adapter you are configuring. You can find the MAC address of your PLA4231 displayed on a sticker on the bottom of your device.

Chapter 5 Using the Powerline Configuration UtilityPLA4231 User’s Guide32The following table describes the labels in this screen. 5.6 Advanced Screen Note: This feature is only available with the latest version utility. Go to the ZyXEL website to download the latest utility and firmware for your ZyXEL HomePlug AV adapter.You can configure the powerline adapters on your network to give priority to network traffic depending on its importance. When you set the priority of a powerline adapter, you set how quickly messages FROM your powerline adapter are sent in your powerline network. Transmissions TO your powerline adapter do not receive any priority.Table 4 Network Info ScreenLABEL DESCRIPTIONAdapter This field identifies which powerline network information is displayed. Different powerline networks are identified by the Ethernet interface (network card) on your computer which is connected directly to a powerline adapter. Typically there is only one connection. However, if your computer has two network cards and both are connected to a powerline adapter, then you have two powerline networks.Central Coordinator MACThe Central Coordinator of the powerline network is the powerline adapter which keeps track of which devices are part of the network as well as synchronizes communication within the powerline network. If the Central Coordinator is removed from the powerline network then another powerline adapter takes its place. This field displays the MAC address of the PLA4231 which is the Central Coordinator of the powerline network. The powerline adapters in your powerline network automatically select the Central Coordinator. The information provided in the following table reflects transmission rate information about the powerline adapters which communicate in your powerline network. The powerline adapters listed in this table are all the powerline adapters in your powerline network except the powerline adapter selected in the Configuration page of the configuration utility. In other words, if the Local powerline adapter is selected in the Configuration screen, then this table will display the rates of transmission from the powerline adapter connected to the computer running the configuration utility to all the Remote powerline adapters.Site This field displays:•Local, if it is the PLA4231 directly connected to the computer running the configuration utility.•Remote, if it is a PLA4231 in your powerline network but not directly connected to the computer running the configuration utility.MAC Address This field displays the MAC address of your powerline adapter. The MAC address of your powerline adapter can be found by looking at the label on your device. It consists of six pairs of hexadecimal characters (hexadecimal characters are “0-9” and “a-f”). In the case of the PLA4231, this label is on the bottom of the device. Transmit Rate (Mbps)This field displays how fast information is sent from the powerline adapter selected in the Configuration screen to this powerline adapter. The rate is given in the following format: “application data transmission rate / raw data transmission rate”. Application data reflects more accurately how fast devices are transmitting application relevant traffic (for example Internet Protocol (IP) traffic). Raw data refers to the whole payload of the packets transmitted across the powerline network.Receive Rate (Mbps)This field displays how fast information is received from the powerline adapter selected in the Configuration screen to this powerline adapter. The rate is given in the following format: “application data transmission rate / raw data transmission rate”. Application data reflects more accurately how fast devices are transmitting application relevant traffic (for example Internet Protocol (IP) traffic). Raw data refers to the whole payload of the packets transmitted across the powerline network.
Chapter 5 Using the Powerline Configuration UtilityPLA4231 User’s Guide 33For example, if you have a file server on your home network to deliver music and movie files to computers in your home, you should set the priority of the powerline adapter connected to this server to Medium. If video traffic is delivered too slowly, quality problems may occur.On the other hand, a powerline adapter attached to a printer should have a low priority setting since the slow delivery of messages will not affect the print job.Similarly, if you want to prioritize any downloads from the Internet, set the priority on the powerline adapter attached to your Internet gateway to High.Allocate priority settings based on application type as follows.The figure below shows an example powerline home network connected to the Internet.• Device A is a printer and does not handle traffic with high importance, so the powerline adapter connected to it can be set to low priority.• Device B is a file server, delivering audio or movie files to other users on the network. The powerline adapter attached to it should have a medium setting.• Device C, a home computer which connects to the Internet, can receive a normal priority setting as it usually sends simple requests for data. For example, when you surf the Internet, your computer sends requests to open web pages.• Device D is a modem attached to the Internet. It should receive a high priority setting if you want faster downloading through your network.• Although device E receives audio or movie files, it does not send a lot of traffic, so the powerline adaptor attached to it can be set to a low priority.Figure 16 Priority SettingsTable 5 Priority SettingsPRIORITY LEVEL APPLICATIONHigh Voice ApplicationMedium Video and Audio ApplicationsNormal Data ApplicationsLow Data ApplicationsABCDE

See the appendices for more detailed information about wireless networks.The following figure provides an example of a wireless network.Figure 44 Example of a Wireless NetworkThe wireless network is the part in the blue circle. In this wireless network, devices A and B are called wireless clients. The wireless clients use the access point (AP) to interact with other devices (such as the printer) or with the Internet. Your PLA4231 is the AP.10.2 What You Can Do•Use the General screen (Section 10.4 on page 66) 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 71) to allow or deny wireless stations based on their MAC addresses from connecting to the PLA4231.ABAP
Chapter 10 Wireless LANPLA4231 User’s Guide64•Use the Advanced screen (Section 10.7 on page 73) 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 73) 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 74) 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 76) to add a wireless station using WPS. •Use the Scheduling screen (Section 10.11 on page 76) to set the times your wireless LAN is turned on and off.10.3 What You Should KnowEvery wireless network must follow these basic guidelines.• Every wireless client in the same wireless network must use the same SSID.The SSID is the name of the wireless network. It stands for Service Set IDentity.• If two wireless networks overlap, they should use different channels.Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information.• Every wireless client in the same wireless network must use security compatible with the AP.Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network.10.3.1 Wireless Security OverviewThe following sections introduce different types of wireless security you can set up in the wireless network.10.3.1.1 SSIDNormally, the AP acts like a beacon and regularly broadcasts the SSID in the area. You can hide the SSID instead, in which case the AP does not broadcast the SSID. In addition, you should change the default SSID to something that is difficult to guess.This type of security is fairly weak, however, because there are ways for unauthorized devices to get the SSID. In addition, unauthorized devices can still see the information that is sent in the wireless network.10.3.1.2 MAC Address FilterEvery wireless client has a unique identification number, called a MAC address.1 A MAC address is usually written using twelve hexadecimal characters2; for example, 00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC address for each wireless client, see the appropriate User’s Guide or other documentation.1. Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless networks. These kinds of wireless devices might not have MAC addresses.2. Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.
Chapter 10 Wireless LANPLA4231 User’s Guide 65You can use the MAC address filter to tell the AP which wireless clients are allowed or not allowed to use the wireless network. If a wireless client is allowed to use the wireless network, it still has to have the correct settings (SSID, channel, and security). If a wireless client is not allowed to use the wireless network, it does not matter if it has the correct settings.This type of security does not protect the information that is sent in the wireless network. Furthermore, there are ways for unauthorized devices to get the MAC address of an authorized wireless client. Then, they can use that MAC address to use the wireless network.EncryptionWireless networks can use encryption to protect the information that is sent in the wireless network. Encryption is like a secret code. If you do not know the secret code, you cannot understand the message.Usually, you should set up the strongest encryption that every wireless client in the wireless network supports. For example, suppose the AP does not have a local user database, and you do not have a RADIUS server. Therefore, there is no user authentication. Suppose the wireless network has two wireless clients. Device A only supports WEP, and device B supports WEP and WPA. Therefore, you should set up Static WEP in the wireless network.Note: It is recommended that wireless networks use WPA-PSK or stronger encryption. WEP encryption are better than none at all, but it is still possible for unauthorized devices to figure out the original information pretty quickly.When you select WPA2-PSK in your PLA4231, you can also select an option (WPA-PSK Compatible) to support WPA as well. In this case, if some wireless clients support WPA and some support WPA2, you should set up WPA2-PSK and select the WPA-PSK Compatible option in the PLA4231.Many types of encryption use a key to protect the information in the wireless network. The longer the key, the stronger the encryption. Every wireless client in the wireless network must have the same key.10.3.1.3 WPSWiFi Protected Setup (WPS) is an industry standard specification, defined by the WiFi Alliance. WPS allows you to quickly set up a wireless network with strong security, without having to configure security settings manually. Depending on the devices in your network, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (Personal Identification Number) in the devices. Then, they connect and set up a secure network by themselves. Table 17 Types of EncryptionWeakest No SecurityStatic WEPWPA-PSKStrongest WPA2-PSK

Because not all devices support 40 MHz channels, select Auto 20/40 MHz to allow the PLA4231 to adjust the channel bandwidth automatically.40 MHz (channel bonding or dual channel) bonds two adjacent radio channels to increase throughput. The wireless clients must also support 40 MHz. It is often better to use the 20 MHz setting in a location where the environment hinders the wireless signal. Select 20 MHz if you want to lessen radio interference with other wireless devices in your neighborhood or the wireless clients do not support channel bonding.802.11 Mode You can select from the following:•802.11b: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to associate with the PLA4231.

Chapter 14 LEDs and TroubleshootingPLA4231 User’s Guide 101What factors may cause intermittent or unstabled wireless connection? How can I solve this problem?The following factors may cause interference:• Obstacles: walls, ceilings, furniture, and so on.• Building Materials: metal doors, aluminum studs.• Electrical devices: microwaves, monitors, electric motors, cordless phones, and other wireless devices.To optimize the speed and quality of your wireless connection, you can:• Move your wireless device closer to the AP if the signal strength is low.• Reduce wireless interference that may be caused by other wireless networks or surrounding wireless electronics such as cordless phones.• Place the AP where there are minimum obstacles (such as walls and ceilings) between the AP and the wireless client. • Reduce the number of wireless clients connecting to the same AP simultaneously, or add additional APs if necessary.• Try closing some programs that use the Internet, especially peer-to-peer applications. If the wireless client is sending or receiving a lot of information, it may have too many programs open that use the Internet. • Position the antennas for best reception. If the AP is placed on a table or floor, point the antennas upwards. If the AP is placed at a high position, point the antennas downwards. Try pointing the antennas in different directions and check which provides the strongest signal to the wireless clients. 14.7 PLA4231 Access and Login ProblemsI don’t know the IP address of my PLA4231.1The default IP address is 192.168.1.2.2If you changed the IP address and have forgotten it, • and your PLA4231 is a DHCP client, you can find your IP address from the DHCP server.
