Security Precautions Wireless LAN uses radio waves instead of LAN cables to send and receive data between a computer and a wireless access point, making it possible to freely establish a LAN connection within a range of the radio waves. However, radio waves can be received through obstacles, such as walls, when within the range. Therefore, if security settings are not made, the following problems may occur. Unauthorized viewing of data An unauthorized third party can intercept the radio waves and view e-mail messages and personal information, such as user ID and password or your credit card information. Unauthorized access An unauthorized third party can access a personal or corporate network and cause the following damage: - Intercepting personal information and confidential information (information leak) - Using a false identity to communicate and disclose information illegally (identity theft) - Changing and transmitting intercepted data (tampering) - Damaging data and systems by spreading a computer virus (destruction) The wireless LAN card and wireless access point have security features to counter these problems. Using the security settings of the wireless LAN equipment can help prevent these problems from occurring. The security settings of the wireless LAN equipment are not configured at the time of purchase. To reduce security problems, configure all security settings of the wireless LAN equipment according to the manual before using the wireless LAN card and wireless access point. Please be aware that the security settings do not provide complete security protection due to wireless LAN specifications. If you are unable to configure the security settings yourself, please contact your local authorized dealer. The customer is responsible for configuring the security settings and understanding the risks inherent in using the product without the security settings configured.

4. Wireless Link Mode and Wireless LAN Function NZ2WL - xxx 19 4. Wireless Link Mode and Wireless LAN Function This chapter describes the major functions of the NZ2WL series as a wireless LAN system and the wireless link modes of the product along with configuration examples of networks available in the wireless link modes. Wireless Link Mode This product has three wireless link modes. The available functions and network configurations differ depending on the mode. Use the wireless link mode most suitable to the type of network you are constructing. For details on the three modes, see "Features" in Chapter 1 and "Comparison of Main Functions" in this chapter. The factory default setting is “Advanced Infrastructure Mode”. Chapters 3 and 5 describe the software setting procedures for the wireless link modes and related items. Standard Infrastructure Mode In this mode, each access point (AP) can accommodate stations (ST) to make up a network. This mode allows the use of multiple APs to configure a wide-area wireless LAN. All communication between wireless terminals must go through an AP. Figure 4.1. Standard Infrastructure Mode In the Standard Infrastructure mode above, all wireless terminals communicate via AP. Roaming functions are supported, allowing login to any AP within range of radio waves. For the IP tunneling function to work properly, one of the APs must be setup as a master AP. * Normal AP: Normally operated device Master AP: Device controlling access points in a network Backup AP: Backup device that operates in case the master AP does not function for some reason
4. Wireless Link Mode and Wireless LAN Function 20 NZ2WL - xxx - Advantages (1) If the IP tunneling function is used, communication can be performed over different routers without changing IP addresses. (2) Allows log-in restrictions (security function). (3) Improves security using the WSL (Wireless Security Link). Compatible Infrastructure Mode This mode allows the product to be networked with other manufacturers’ Wi-Fi certified wireless terminals other than the NZ2WL series. Communications between the wireless terminals are always made via the APs. CAUTION The Compatible Infrastructure mode does not guarantee interconnection with Wi-Fi compliant products of other manufacturers. Figure 4.2. Compatible Infrastructure Mode In the Compatible Infrastructure mode, each wireless terminal performs communication via the AP as in the Standard Infrastructure mode. Roaming functions are supported, allowing login to any AP within range of radio waves. APs do not provide NZ2WL series' unique functions since APs work as a simple bridge.
4. Wireless Link Mode and Wireless LAN Function NZ2WL - xxx 21 Advanced Infrastructure Mode The Advanced Infrastructure mode is a mixture of the Standard Infrastructure and Compatible Infrastructure modes. The Advanced Infrastructure mode can be used only when the product is configured as an access point. Figure 4.3. Advanced Infrastructure Mode On the terminal set to the Standard Infrastructure mode, the NZ2WL series' unique functions can be used. The terminal set to the Compatible Infrastructure mode serves as a simple bridge and thus the NZ2WL series’ unique functions cannot be used on this terminal.
4. Wireless Link Mode and Wireless LAN Function 22 NZ2WL - xxx Comparison of Main Functions The three wireless connection modes mentioned earlier have different wireless LAN functions. The following table lists main functions of each mode and gives a brief explanation of each function. " " indicates that the function can be used and " " indicates that the function cannot be used.

Roaming The roaming function allows stations to switch logins between multiple APs. The roaming function can be used to construct a wide-area wireless LAN. IP tunneling With this function, the AP changes an IP address to allow a station to connect to a device in the desired network group via access point in the different network group. This function is unique to the NZ2WL series and cannot be used between an access point set to the Compatible Infrastructure mode and a station set to the Compatible Infrastructure mode. SNMP This function enables remote management using software that supports SNMP. This function can be used in all the modes. Log collection function This function collects event information such as a wireless communication of this product. For details, refer to Chapter 6.
4. Wireless Link Mode and Wireless LAN Function NZ2WL - xxx 23 MAC address filtering This function can be used only when the product is configured as an access point. This function enables only the terminals whose MAC address has been registered to be connected. Bridge packet control This function can be used only when the product is configured as an access point. An AP can pass only data from network devices whose MAC address has been registered to the AP. Communication between wireless terminals can be rejected when their MAC addresses are unregistered. WSL (Proprietary encryption) WSL (Wireless Security Link) is unique proprietary encryption built only in the NZ2WL series of devices. It can be used either alone or along with other types of encryption such as WEP and AES. Note, however, that devices using WSL cannot communicate with those not using it. Data encryption This function encrypts wireless data. For encryption, four security protocols are available: WEP (Wired Equivalent Privacy), AES, AES-OCB and TKIP. AES and TKIP can be used with WPA, WPA-PSK, WPA2, WPA2-PSK, WPA-AUTO, and WAP-AUTO-PSK. Super A/G Proposed by Atheros Communications, Inc., this technology speeds up communication. It improves the throughput of wireless LAN using three techniques: "fast frames" for raising data transfer efficiency by increasing the data packet size, "bursting" for decreasing inter-packet wait time, and "compression" for compressing and decompressing data in real time. VLAN function This function can be used only when the product is configured as an access point. This function organizes terminals on a network into virtual groups regardless of the physical configuration of the network. WDS function This function can be used only when the product is configured as an access point. This function is a wireless communication function between APs. An AP can wirelessly communicate with other APs while communicating with a station. XR Promoted by Atheros Communications, Inc., this technology makes the communication distance longer, compared with the existing communication distance, although the communication speed decreases. XR can be used both in IEEE802.11a and IEEE802.11g specifications. For communication using XR, the product must be connected to a device which supports the XR technology and has the XR function enabled. If it is connected to any other device, XR will not be used and only the regular wireless communication is available.
4. Wireless Link Mode and Wireless LAN Function 24 NZ2WL - xxx Installation in a Network This section describes how to install the product to construct a network with improved performance and discusses the general features of the wireless network and characteristics of radio waves, as well as the guidelines for constructing the network. Features of the Wireless Network In general, the operation of a wireless network is the same as for other similar types of LAN. The most prominent feature of the wireless network is that it uses radio waves as its medium, eliminating the need for cabling. The wireless network thus requires no cabling cost and has other advantages as listed below: - Quick construction of a LAN - Temporary installation of a LAN - Higher flexibility in layout of connected PCs (terminals) - Assured mobility of connected PCs (terminals) On the other hand, the wireless network has the following drawbacks from the operational point of view due to the nature of radio waves : - Signal attenuation - Signal interference Also, although this product does not require a radio license, it is subject to radio regulations of each country.
4. Wireless Link Mode and Wireless LAN Function NZ2WL - xxx 25 Operating Environment and Radio Waves When using this product to construct a network, install and operate it considering the radio environment to optimize the performance. Is it allowed to use wireless devices at the installation location? In some medical institutions and laboratories, radio-sensitive precision instruments are used and it may be prohibited to use wireless devices. Radio waves are attenuated. Although a radio wave is attenuated naturally as it travels from its transmission source, it may also be attenuated by an object existing in its way. Major obstacles that attenuate radio waves are as follows: - Concrete wall - Metal surfaces in the vicinity of the antenna Obstacles blocking radio waves include metal walls and walls containing a metal firewall. Strictly speaking, nearly all objects in the path of the radio waves (such as partitions and people) cause some attenuation, but these do not have a significant impact on network performance. RSSI (Receive Signal Strength Indication) utility is available as a means of knowing the signal strength of an incoming radio wave. Placing this product for a greater RSSI value makes the communication state more stable. If the RSSI value is small and does not increase by slightly moving the position of the product, it means that the radio waves may be being attenuated by distance or obstacles. Pay attention to radio interference. Radio interference means that radio waves in the frequency band used by this network occurred outside the network this product belongs to and that the reception of the radio waves is affected. Listed below are major examples of sources of interfering radio waves generated in general environments other than plants and factories: - 5GHz (using IEEE802.11a) or 2.4GHz (using IEEE802.11b/IEEE802.11g) band wireless networks that do not comply with IEEE802.11 - Using IEEE802.11b/IEEE802.11g. (e.g. electronic devices that give off 2.4GHz band radio waves, such as microwave ovens, security gates installed near entrances of some shops, and copiers) When there is a large metal wall such as in a warehouse, the radio wave generated from the sender is reflected, resulting in those radio waves reaching the receiver which have taken different routes (thereby phase-shifted). This has the similar effect as the generation of interfering radio waves, possibly slowing down data transfer. Most of the interfering radio wave sources other than wireless networks have local and/or temporary effects, not giving great effect to the network performance. Rarely, however, communication speed is decreased and communication is disabled temporarily in the worst case. In such cases, changing the location of this product may solve the problem.
4. Wireless Link Mode and Wireless LAN Function 26 NZ2WL - xxx Constructing a Network This section gives some pointers and cautions relating to constructing a network using the AP and station and provides some practical examples. (1) This product conforms with the standard wireless LAN specifications such as IEEE802.11a, IEEE802.11g and IEEE802.11b. This enables setting to the same channel as that used in each country and wireless communication between access points and stations responding to each channel. Using different channels for wireless networks adjacent to each other (In IEEE802.11a, set it to a channel such as 36 and 44 with 8ch or more apart, and in IEEE802.11g, a channel such as 1, 6, and 11 with 5ch or more apart) prevents radio interference and improves the throughput of the networks. (2) Check the range of radio waves (hereinafter collectively called "cover area"). To use the AP with two or more station logged in AP, all the stations must be installed within the cover area. The AP’s coverage varies with obstacles (concrete walls, iron doors, elevator halls, etc.). Note also that the number of transmission/reception errors increases if communication distance becomes longer to some extent. When setting up the network, check the RSSI level then confirm that communication works correctly with the application you plan to use. For a TCP/IP system, for example, you can use the Windows PING command. To use PING, start the command prompt (MS-DOS) and enter the following command. The example command is for an AP with an IP address of 10.144.0.1, as follows. ping 10.144.0.1 (3) Two or more stations can log in the AP at the same time. However, remember that the communication speed slows due to the increased loading as the number of stations increases for one AP. (4) If a pair of wireless terminals are communicating via a particular channel, no other devices can communicate within the range of those radio waves (the exception is broadcasting which transmits to all terminals). As a result, communication speed tends to drop as the density of wireless terminals increases although this depends to a large extent on how frequently the network is used. (5) If the AP is connected to an Ethernet hub or similar, an unexpectedly large load can occur on the AP if the Ethernet traffic is heavy and this may reduce the performance of the wireless network. This can be solved by changing the hub connected to the AP to a switching hub (bridge). (6) Setup the software in accordance with how the network will be used. (7) The communication speed may also drop due to interference if two wireless terminals are located close to each other. In general, maintain a gap of about 1m between stations, 3m between APs and stations, and 3m between APs. (8) The best performance is achieved from antennas if they are located in an open space free from obstructions. Avoid locating antennas where they will be hidden. In particular, when communication distance is an important consideration, it is recommended that you install antennas in a high location with a clear view. (9) Floors often contain steel beams or metal firewalls and therefore communication on different floors is often not possible.

5. Setup and Status Display NZ2WL - xxx 29 ◆Ethernet Port Speed Select the port speed setting. Select one of “Auto”, “100M Full Duplex”, “100M half Duplex”, “10M Full Duplex”, or “10M half Duplex”. Factory default setting: Auto CAUTION - If one side is set to "Auto" and the other side is set to "100M Full Duplex", the communication mode for the "Auto" side is recognized as "100M half Duplex". In this case, there may be a high error rate and normal communication may not be possible. It is recommended that you set the correct communication mode. - If one side or both sides are set to "Auto" and the two sides cannot recognize each other, set the communication mode to the unchanging setting for both sides. - If port speeds are set incorrectly (for example, one side is set to unchanging 10M and the other side is set to unchanging 100M), only one device may be able to establish a link or the link may be repeatedly established and disconnected depending on the communication status. In this case, set the correct communication mode. Link Down Sense Enabling the link down sense feature stops the wireless function when a link is regarded to be down in the wired LAN at an access point. The condition for detecting the link down-state is selected as a link-down condition: "Link status" or "Ping". "Link status" sets the condition to "when a physical link is disconnected at the wired LAN port of the product". "Ping" issues a ping packet periodically to a specified communication destination and sets the condition to "when a reply error occurs". Factory default setting: Wireless LAN … Disable Link Down Condition … LinkStatus Ping Parameter These parameters are used when "Ping" is selected as the link-down condition.

7. Troubleshooting 60 NZ2WL - xxx 7. Troubleshooting This chapter describes common problems that may occur with this product and what to do about them. If a problem not described here occurs or the same problem occurs after checking the nature of the problem, contact your local authorized dealer. When Communication Fails Check wired LAN communication Check the wired LAN communication between this product and the connected PC. - Check that the LAN cable is connected correctly. - Check if the IP addresses and subnet masks of the product and PC are set correctly. (See "Preparation before Setup" in Chapter 3.) - To connect the product to a PC directly, a cross cable must be used. Check to see if a straight cable is used instead for the connection. (See "Wired LAN Connection" in Chapter 2.) - When the product is connected to a PC through a HUB, the cable connecting this product and the HUB must be selected depending on the HUB port. Check if the correct cable is used for the connection. If the HUB port supports AUTO-MDIX, either a straight or cross cable can be used. For the UPLINK port, a cross cable must be used to connect the product. - The communication with this product is not possible unless the TCP/IP protocol is installed in the PC. Check wireless LAN communication If no problem is detected in the wired LAN communication between the product and PC, check the wireless LAN communication between the product and access point. - The terminals that cannot communicate with each other may have different ESSIDs. Two terminals with different ESSIDs cannot communicate with each other. - Check whether the wireless link mode has been set correctly. The AP to be logged in to and the product must have the same wireless connection mode. (If the access point is set to "Standard Infrastructure", this product should also be set to "Standard Infrastructure".) - Check whether communication is restricted by security functions such as the MAC address filtering. - Check whether the data encryption setting is the same as that of the recipient. Communication cannot be performed between devices with different types of encryption.
7. Troubleshooting NZ2WL - xxx 61 Check the peripheral environment and place of installation - A nearby source of electromagnetic interference may prevent communication. In general locations (excluding factories) the following may be sources of electromagnetic emissions. - 5GHz band not conforming to IEEE802.11 (when using IEEE802.11a) or 2.4GHz band (when using IEEE802.11b/IEEE802.11g) wireless network - Electronic devices that give off 2.4GHz band radio waves, such as microwave ovens, security gates installed near entrances of some shops, and copiers, when using IEEE802.11b/IEEE802.11g Most electromagnetic sources other than wireless networks are local and not continuous. Moving the location of the product and waiting for a while may enable communication. - Sometimes communication is hindered by attenuation of radio waves. Attenuation occurs naturally as distance from the source of transmission increases, but may also be caused by objects in the path of the transmission. The objects primarily responsible for attenuation are the following. - Concrete walls - Metallic surfaces around this product Setup Screen Unavailable on Web Browser - Check if communication is possible between the product and PC. - If no problem is detected in the communication between the product and PC, it may be related to the browser settings. For the browser settings, see Chapter 3 “Connection to Devices and Setup Methods”. When the Product Does Not Start Check the power LED - Check whether the “POWER” LED is ON. If it is not ON, check the power supply cable and confirm that it is properly connected to the proper connector and outlet. - Check whether the Power LED is flashing. If the power LED still flashes for more than 5 minutes after the power is switched on, the firmware of the product may be in failure. Contact your local authorized dealer. Check the power - When power is supplied using the proper connector, check the power supply connection and the voltage for any problems. See "Chapter 2. Setup" for details of the power supply connections.
