User’s Guide P ART I User’s Guide 11 12 C HAPT ER Introduction 1.1 Overview This chapter introduces the main features and applications of the NBG2105. The NBG2105 extends the range of your existing wired network without additional wiring, providing easy network access to mobile users. You can set up a wireless network with other IEEE 802.11b/g/ n compatible devices. A range of services such as a firewall and content filtering are also available for secure Internet computing. 1.2 Applications Your can have the following networks using the NBG2105: • Wired. You can connect network devices via the Ethernet ports of the NBG2105 so that they can communicate with each other and access the Internet. • Wireless. Wireless clients can connect to the NBG2105 to access network resources. You can use WPS (WiFi Protected Setup) to create an instant network connection with another WPScompatible device. • WAN. Connect to a broadband modem/router for Internet access. 1.3 Ways to Manage the NBG2105 Use any of the following methods to manage the NBG2105. • WPS (Wi-Fi Protected Setup). You can use the WPS button or the WPS section of the Web Configurator to set up a wireless network with your ZyXEL Device. • Web Configurator. This is recommended for everyday management of the NBG2105 using a (supported) web browser. 1.4 Good Habits for Managing the NBG2105 Do the following things regularly to make the NBG2105 more secure and to manage the NBG2105 more effectively. NBG2105 User’s Guide 13 Chapter 1 Introduction • 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 NBG2105 to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the NBG2105. You could simply restore your last configuration. 1.5 Resetting the NBG2105 If you forget your password or IP address, or you cannot access the Web Configurator, you will need to use the RESET button on the underside of the NBG2105 to reload the factory-default configuration file. This means that you will lose all configurations that you had previously saved, the password and the IP address will be reset to the defaults shown on the cover of this user’s guide. 1.5.1 How to Use the RESET Button Make sure the power LED is on. Press the RESET button for longer than five seconds (when the power LED begins to blink) and release it to set the NBG2105 back to its factory-default configurations. 1.6 The WPS Button Your NBG2105 supports WiFi Protected Setup (WPS), which is an easy way to set up a secure wireless network. 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. 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. You can use the WPS button to activate WPS in order to quickly set up a wireless network with strong security. 14 Make sure the power LED is on (not blinking). Press the WPS button for less than two seconds and release it. Press the WPS button on another WPS-enabled device within range of the NBG2105. NBG2105 User’s Guide Chapter 1 Introduction Note: You must activate WPS in the NBG2105 and in another wireless device within two minutes of each other. For more information on using WPS, see Section 8.2 on page 59. 1.7 The Clone MAC Button Your NBG2105 can clone the MAC address of the computer connected to the NBG2105. It is recommended that you clone the MAC address prior to hooking up the WAN port or connecting to an AP or wireless router with Internet access. Note: MAC cloning is supported only when the NBG2105 is in Router mode. 1.7.1 Cloning a computer's MAC address Make sure the power LED is on (not blinking). To copy and use the MAC address of a currently connected computer through a wired Ethernet or wireless LAN connection, press the Clone MAC button for two to five seconds and release it. The WPS/MAC Clone LED turns on when the clone was successful. The NBG2105 restarts automatically ten seconds after you press the Clone MAC button. 1.7.2 Restoring the default MAC address Make sure the power LED is on (not blinking). Press and hold the Clone MAC button for more than five seconds to reset the NBG2105 back to the factory default MAC address. The Clone MAC Address in the WAN screen shows 000000000000 to indicate the NBG2105 is using the factory default MAC address. The NBG2105 restarts after you press the Clone MAC button.

NBG2105 User’s Guide Chapter 3 Operation Modes 3.6 WISP + UR Mode In WISP (Wireless ISP) + UR (Universal Repeater) mode, your NBG2105 can act as a wireless client to wirelessly connect to the Internet or an existing network via an access point. In addition, it can provide Wi-Fi function to the clients on the LAN side. Use this mode if you want to wirelessly connect to the Internet or have an access point or wireless router in your network. In WISP + UR mode, the IP address of the device on the local network is 192.168.1.2. Note: Make sure your network and the remote network are NOT in the same subnet. If the access point or wireless router is using 192.168.1.x, the NBG2105 in WISP + UR mode needs to use something else, say 192.168.2.x. Note: When the NBG2105 is in WISP + UR mode, you still need to enter your ISP information in the WAN screen in order to access the Internet. In the example below, one NBG2105 is configured as WISP +UR mode (A) and another is used as an access point (B). The NBG2105 (A) wirelessly connects to the available access point (B), and can allow the clients (x and y) to access the network through it using a wireless connection.

Back Click this to go back to the previous step in the wizard. Next Click this to go to the next step in the wizard. 4.3.3 WAN Access Type: PPPoE Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an IETF (Internet Engineering Task Force) standard specifying how a host personal computer interacts with a broadband modem (for example DSL, cable, wireless, etc.) to achieve access to high-speed data networks. For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for instance, RADIUS). One of the benefits of PPPoE is the ability to let end users access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for specific users. Operationally, PPPoE saves significant effort for both the subscriber and the ISP/carrier, as it requires no specific configuration of the broadband modem at the subscriber's site. By implementing PPPoE directly on the NBG2105 (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG2105 does that part of the task. Furthermore, with NAT, all of the LAN's computers will have Internet access. Select PPPoE as the WAN Access Type to make the WAN port setup its IP configuration via PPPoE. Complete the fields described. Click Next to proceed with the Wireless Network Name (SSID) screen.

NBG2105 User’s Guide 57 Chapter 7 WISP+UR Setup Wizard 58 NBG2105 User’s Guide C HAPT ER Tutorials 8.1 Overview This chapter provides tutorials for setting up your NBG2105. • Set Up a Wireless Network with WPS • Configure Wireless Security without WPS 8.2 Set Up a Wireless Network with WPS This section gives you an example of how to set up wireless network using WPS. This example uses the NBG2105 as the AP and NWD210N as the wireless client which connects to a notebook. Note: The wireless client must be a WPS-aware device (for example, a WPS USB adapter or PCI card). There are two WPS methods for creating a secure connection. This tutorial shows you how to do both. • Push Button Configuration (PBC) - create a secure wireless network simply by pressing a button. See Section 8.2.1 on page 59.This is the easier method. • PIN Configuration - create a secure wireless network simply by entering a wireless client's PIN (Personal Identification Number) in the NBG2105’s interface. See Section 8.2.2 on page 60. This is the more secure method, since one device can authenticate the other. 8.2.1 Push Button Configuration (PBC) Make sure that your NBG2105 is turned on and working as an AP or wireless router. Make sure that the device is placed within range of your notebook. Make sure that you have installed the wireless client (this example uses the NWD210N) driver and utility in your notebook. In the wireless client utility, find the WPS settings. Enable WPS and press the WPS button (Start or WPS button) Log into NBG2105’s Web Configurator and press the Start PBC button in the Wireless LAN > WPS screen. NBG2105 User’s Guide 59 Chapter 8 Tutorials Note: Your NBG2105 has a WPS button located on its panel, as well as a WPS button in its configuration utility. Both buttons have exactly the same function; you can use one or the other. Note: It doesn’t matter which button is pressed first. You must press the second button within two minutes of pressing the first one. The NBG2105 sends the proper configuration settings to the wireless client. This may take up to two minutes. Then the wireless client is able to communicate with the NBG2105 securely. The following figure shows you an example to set up wireless network and security by pressing a button on both NBG2105 and wireless client (the NWD210N in this example). Figure 38 Example WPS Process: PBC Method Wireless Client Access Point WITHIN 2 MINUTES SECURITY INFO COMMUNICATION 8.2.2 PIN Configuration When you use the PIN configuration method, you need to use both NBG2105’s configuration interface and the client’s utilities. 60 Launch your wireless client’s configuration utility. Go to the WPS settings and select the PIN method to get a PIN number. Enter the PIN number into the Station PIN Number field in the Wireless LAN > WPS screen on the NBG2105. NBG2105 User’s Guide Chapter 8 Tutorials Click Start buttons (or button next to the PIN field) on both the wireless client utility screen and the NBG2105’s Wireless LAN > WPS screen within two minutes. The NBG2105 authenticates the wireless client and sends the proper configuration settings to the wireless client. This may take up to two minutes. Then the wireless client is able to communicate with the NBG2105 securely. The following figure shows you the example to set up wireless network and security on NBG2105 and wireless client (ex. NWD210N in this example) by using PIN method.

NBG2105 User’s Guide 65 Chapter 8 Tutorials 66 NBG2105 User’s Guide P ART II Technical Reference 67 68 C HAPT ER LAN 9.1 Overview This chapter describes how to configure LAN settings. A Local Area Network (LAN) is a shared communication system to which many computers are attached. A LAN is a computer network limited to the immediate area, usually the same building or floor of a building. The LAN screens can help you configure a LAN DHCP server and manage IP addresses. Figure 40 LAN Example 9.2 What You Can Do • Use the LAN Interface Setup screen to change the IP address for your NBG2105 (Section 9.4 on page 70). • Use the Active DHCP Client screen to see which DHCP clients have accepted their IP configuration from the NBG2105 (Section 9.4.1 on page 71). 9.3 What You Need To Know The LAN parameters of the NBG2105 are preset in the factory with the following values: • IP address of 192.168.1.1 (Router mode) or 192.168.1.2 (non-router modes) with subnet mask of 255.255.255.0 (24 bits) • DHCP server enabled (Router mode or WISP+UR mode) with client IP addresses starting from 192.168.1.100 and ending with 192.168.1.200. These parameters should work for the majority of installations. If your ISP gives you explicit DNS server address(es), read the embedded Web Configurator help regarding what fields need to be configured. NBG2105 User’s Guide 69 Chapter 9 LAN 9.3.1 IP Pool Setup The NBG2105 is pre-configured with a pool of IP addresses starting from 192.168.1.100 to 192.168.1.200. This configuration leaves 98 IP addresses (excluding the NBG2105 itself) under 192.168.1.99 for other server computers, for instance, servers for mail, FTP, TFTP, web, etc., that you may have. 9.3.2 LAN TCP/IP The NBG2105 has built-in DHCP server capability that assigns IP addresses and DNS servers to systems that support DHCP client capability. 9.4 LAN Interface Setup Screen Use this screen to change the IP address for your NBG2105 and configure the DHCP server.

NBG2105 User’s Guide 71 Chapter 9 LAN 72 NBG2105 User’s Guide C HAPTER 10 WAN 10.1 Overview This chapter discusses the NBG2105’s WAN screens. Use these screens to configure your NBG2105 for Internet access. A WAN (Wide Area Network) connection is an outside connection to another network or the Internet. It connects your private networks such as a LAN (Local Area Network) and other networks, so that a computer in one location can communicate with computers in other locations. 10.2 What You Can Do You can configure your WAN interface to access your ISP in the following ways. • Static IP allows you to configure all NBG2105 WAN IP configuration settings manually (Section 10.4.1 on page 74). • DHCP Client allows the NBG2105 to get its IP configuration from a DHCP server (Section 10.4.2 on page 75). • PPPoE allows the NBG2105 to connect via the Point-to-Point Protocol over Ethernet (Section 10.4.3 on page 76). 10.3 What You Need To Know The information in this section can help you configure the screens for your WAN connection. 10.3.1 Configuring Your Internet Connection Encapsulation Method Encapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set up a WAN connection to the Internet, you need to use the same encapsulation method used by your ISP (Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP over Ethernet), they should also provide a username and password (and service name) for user authentication. NBG2105 User’s Guide 73 Chapter 10 WAN WAN IP Address The WAN IP address is an IP address for the NBG2105, which makes it accessible from an outside network. It is used by the NBG2105 to communicate with other devices in other networks. It can be static (fixed) or dynamically assigned by the ISP each time the NBG2105 tries to access the Internet. If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and DNS server IP address(es) (and a gateway IP address if you use the Ethernet or ENET ENCAP encapsulation method). DNS Server Address Assignment Use Domain Name System (DNS) to map a domain name to its corresponding IP address and vice versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it. The NBG2105 can get the DNS server addresses in the following ways. The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up. If your ISP gives you DNS server addresses, manually enter them in the DNS server fields. If your ISP dynamically assigns the DNS server IP addresses (along with the NBG2105’s WAN IP address), set the DNS server fields to get the DNS server address from the ISP. WAN MAC Address The WAN port's MAC address can be configured by either using the factory default or cloning the MAC address from a computer on your LAN. Choose Clear Mac Clone to select the factory assigned default MAC Address. Otherwise, press the Clone MAC address button on the side of the NBG2105 to clone the MAC address of the computer connected to the NBG2105. Once it is successfully configured, the address will be copied to configuration file. It is recommended that you clone the MAC address prior to hooking up the WAN Port. 10.4 WAN Interface Setup Click Network > WAN to change how your NBG2105’s WAN interface accesses your ISP. The screen differs according to the WAN Access Type you choose. 10.4.1 Static IP Select Static IP from WAN Access Type to configure all NBG2105 WAN IP configuration settings manually. 74 NBG2105 User’s Guide Chapter 10 WAN Figure 43 Network > WAN: Static IP The following table describes the labels in this screen.

Reset Click this to begin configuring this screen afresh. 10.4.3 PPPoE The NBG2105 supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.) connection. The PPPoE option is for a dial-up connection using PPPoE. For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for example Radius). One of the benefits of PPPoE is the ability to let you access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for individuals. 76 NBG2105 User’s Guide Chapter 10 WAN Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no specific configuration of the broadband modem at the customer site. By implementing PPPoE directly on the NBG2105 (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG2105 does that part of the task. Furthermore, with NAT, all of the LANs’ computers will have access. Select PPPoE from WAN Access Type to make the NBG2105 get its IP configuration via PPPoE.

NBG2105 User’s Guide 77 Chapter 10 WAN 78 NBG2105 User’s Guide C HAPTER 11 Quality of Service (QoS) 11.1 Overview Quality of Service (QoS) refers to both a network’s ability to deliver data with minimum delay, and the networking methods used to control the use of bandwidth. Without QoS, all traffic data is equally likely to be dropped when the network is congested. This can cause a reduction in network performance and make the network inadequate for time-critical application such as video-ondemand. Configure QoS on the NBG2105 to reserve bandwidth for certain traffic based on the IP address or MAC address. 11.2 QoS Setup Screen Click Network > QoS to show the QoS Setup screen.

NBG2105 User’s Guide C HAPTER 13 Wireless LAN 13.1 Overview This chapter discusses how to configure the wireless network settings in your NBG2105. See the appendices for more detailed information about wireless networks. The following figure provides an example of a wireless network. Figure 48 Example of a Wireless Network The 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 NBG2105 is the AP. 13.1.1 What You Can Do • Use the Basic screen to turn the wireless connection on or off and make other basic configuration changes (Section 13.2 on page 86). • Use the Advanced screen to configure wireless advanced features, such as the output power and set the RTS/CTS Threshold (Section 13.4 on page 88). • Use the Security screen to set up wireless security between the NBG2105 and the wireless clients (Section 13.5 on page 89). NBG2105 User’s Guide 83 Chapter 13 Wireless LAN • Use the Site Survey screen to scan for and connect to a wireless network automatically. (Section 13.6 on page 92) • Use the WPS screen to quickly set up a wireless network with strong security, without having to configure security settings manually (Section 13.8 on page 95). • Use the MAC Filtering screen to allow or deny wireless stations based on their MAC addresses from connecting to the NBG2105 (Section 13.9 on page 97). 13.1.2 What You Should Know Every 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. Wireless Security Overview The following sections introduce different types of wireless security you can set up in the wireless network. SSID Normally, 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. Authentication Authentication is the process of confirming a client’s user name and password when they connect to a network. Turning off authentication means allowing anyone to connect to the network. Encryption Wireless networks can use encryption to protect the information that is sent in the wireless network. It is the process of taking data and encoding it, usually using a secret code, so that it becomes unreadable unless decrypted with the proper code or pass phrase. If you do not know the secret code, you cannot understand the message. 84 NBG2105 User’s Guide Chapter 13 Wireless LAN WEP Data Encryption WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the NBG2105 and the AP or other wireless stations to keep network communications private. Both the wireless stations and the access points must use the same WEP key for data encryption and decryption. Authentication Type The IEEE 802.11b/g/n standard describes a simple authentication method between the wireless stations and AP. Three authentication types are defined: Both, Open and Shared. • Open mode is implemented for ease-of-use and when security is not an issue. The wireless station and the AP or peer computer do not share a secret key. Thus the wireless stations can associate with any AP or peer computer and listen to any transmitted data that is not encrypted. • Shared mode involves a shared secret key to authenticate the wireless station to the AP or peer computer. This requires you to enable the wireless LAN security and use same settings on both the wireless station and the AP or peer computer. • Both authentication mode allows the NBG2105 to switch between the open system and shared key modes automatically. Use this mode if you do not know the authentication mode of the other wireless stations. WPA-PSK and WPA2-PSK Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA. Key differences between WPA(2) and WEP are improved data encryption and user authentication. Both WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x. WPA and WPA2 use Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP) to offer stronger encryption than TKIP. The encryption mechanisms used for WPA(2) and WPA(2)-PSK are the same. The only difference between the two is that WPA(2)-PSK uses a simple common password, instead of user-specific credentials. The common-password approach makes WPA(2)-PSK susceptible to brute-force password-guessing attacks but it’s still an improvement over WEP as it employs a consistent, single, alphanumeric password to derive a PMK which is used to generate unique temporal encryption keys. This prevent all wireless devices sharing the same encryption keys. (a weakness of WEP) If both an AP and the wireless clients support WPA2-PSK, use WPA2-PSK for stronger data encryption. If the AP or the wireless clients do not support WPA2-PSK, just use WPA-PSK. Select WEP only when the AP and/or wireless clients do not support WPA-PSK or WPA2-PSK. WEP is less secure than WPA-PSK or WPA2-PSK. NBG2105 User’s Guide 85 Chapter 13 Wireless LAN MAC Address Filter Every 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. You 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. WPS WiFi 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. See how to set up a secure wireless network using WPS in the Section 8.2 on page 59. 13.2 Wireless Basic Screen Click Wireless LAN > Basic to make basic wireless configuration changes.

The NBG2105 firewall is a packet filtering firewall and restricts access based on the source/ destination computer network address of a packet and the type of application. 14.2 What You Can Do • Use the Port Filtering screen to apply filtering based on UDP or TCP port numbers (Section 14.4 on page 100). • Use the IP Filtering screen to apply filtering based on IP addresses (Section 14.5 on page 101). • Use the MAC Filtering to apply filtering based on MAC addresses (Section 14.6 on page 101). • Use the URL Filtering to apply filtering based on URLs (Section 14.7 on page 102). 14.3 What You Need To Know The following terms and concepts may help as you read through this chapter. What is a Firewall? A "firewall" is a system or group of systems that enforces an access-control policy between two networks. Of course, firewalls cannot solve every security problem. Guidelines For Enhancing Security Change the default password via Web Configurator. Think about access control before you connect to the network in any way, including attaching a modem to the port. Limit who can access your router. Don't enable any local service (such as NTP) that you don't use. Any enabled service could present a potential security risk. A determined hacker might be able to find creative ways to misuse the enabled services to access the firewall or the network. NBG2105 User’s Guide 99 Chapter 14 Firewall For local services that are enabled, protect against misuse. Protect by configuring the services to communicate only with specific peers, and protect by configuring rules to block packets for the services at specific interfaces. Keep the NBG2105 in a secured (locked) room. 14.4 Port Filtering Screen Click Firewall > Port Filtering to apply filtering based on UDP or TCP port numbers.

The potential problems are divided into the following categories. • Power, Hardware Connections, and LEDs • NBG2105 Access and Login • Internet Access • Resetting the NBG2105 to Its Factory Defaults • Wireless LAN Connections 17.2 Power, Hardware Connections, and LEDs The NBG2105 does not turn on. None of the LEDs turn on. Make sure you are using the power adaptor included with the NBG2105 or have connected the NBG2105 to a computer using a USB cable. Make sure the power adaptor is connected to the NBG2105 and plugged in to an appropriate power source. Make sure the power source is turned on. Disconnect and re-connect the power adaptor to the NBG2105. If the problem continues, contact the vendor. One of the LEDs does not behave as expected. Make sure you understand the normal behavior of the LED. See Section 1.8.1 on page 17. Check the hardware connections. See the Quick Start Guide. Inspect your cables for damage. Contact the vendor to replace any damaged cables. Disconnect and re-connect the power adaptor to the NBG2105. If the problem continues, contact the vendor. NBG2105 User’s Guide 121 Chapter 17 Troubleshooting 17.3 NBG2105 Access and Login I don’t know the IP address of my NBG2105. The default IP address of the NBG2105 in Router mode is 192.168.1.1. The default IP address of the NBG2105 in other modes is 192.168.1.2. If you changed the IP address and have forgotten it, you might get the IP address of the NBG2105 (in Router or WISP+UR mode) by looking up the IP address of the default gateway for your computer. To do this in most Windows computers, click Start > Run, enter cmd, and then enter ipconfig. The IP address of the Default Gateway might be the IP address of the NBG2105 (it depends on the network), so enter this IP address in your Internet browser. If your NBG2105 (in Router, AP or WISP+UR mode) is a DHCP client and obtains a dynamic IP address from a DHCP server, use the domain name "zyxelsetup.com" to access the NBG2105. Reset your NBG2105 to change all settings back to their default. This means your current settings are lost. See Section 17.5 on page 124 in the Troubleshooting for information on resetting your NBG2105. I forgot the password. The default password is 1234. If this does not work, you have to reset the device to its factory defaults. See Section 17.5 on page 124. I cannot see or access the Login screen in the Web Configurator. Make sure you are using the correct IP address. • The default IP address of the NBG2105 in Router mode is 192.168.1.1. The default IP address of the NBG2105 in other modes is 192.168.1.2. • If you changed the IP address, use the new IP address. • If you changed the IP address and have forgotten it, see the troubleshooting suggestions for I don’t know the IP address of my NBG2105. 122 Check the hardware connections, and make sure the LEDs are behaving as expected. See the Quick Start Guide. Make sure your Internet browser does not block pop-up windows and has JavaScript and Java enabled. See Appendix A on page 127. Make sure your computer is in the same subnet as the NBG2105. NBG2105 User’s Guide Chapter 17 Troubleshooting • If there is a DHCP server on your network, make sure your computer is using a dynamic IP address. See Section 9.4 on page 70. • If there is no DHCP server on your network, make sure your computer’s IP address is in the same subnet as the NBG2105. See Section 9.4 on page 70. Reset the device to its factory defaults, and try to access the NBG2105 with the default IP address. See Section 1.5 on page 14. If the problem continues, contact the network administrator or vendor, or try one of the advanced suggestions. I can see the Login screen, but I cannot log in to the NBG2105. Make sure you have entered the password correctly. The default password is 1234. This field is case-sensitive, so make sure [Caps Lock] is not on. This can happen when you fail to log out properly from your last session. Try logging in again after 5 minutes. Disconnect and re-connect the USB cable to restart the NBG2105. If this does not work, you have to reset the device to its factory defaults. See Section 1.5.1 on page 14. 17.4 Internet Access I cannot access the Internet. Check the hardware connections, and make sure the LEDs are behaving as expected. See the Quick Start Guide. Check your Operation Mode setting. • If the NBG2105 is in Router mode make sure the WAN port is connected to a broadband modem or router with Internet access. Your computer and the NBG2105 should be in the same subnet. • If the NBG2105 is in Access Point mode, make sure the Ethernet port is connected to a broadband modem or router with Internet access and your computer is set to obtain an dynamic IP address. • If the NBG2105 is in Client mode, make sure the NBG2105 is wirelessly connected to an access point or wireless router with Internet access. Your computer should be set to obtain an dynamic IP address. • If the NBG2105 is in WISP + UR mode, make sure the NBG2105 is wirelessly connected to an access point or wireless router with Internet access. NBG2105 User’s Guide 123 Chapter 17 Troubleshooting If the NBG2105 is in Router or WISP+UR mode make sure you entered your ISP account information correctly in the wizard or the WAN screen. These fields are case-sensitive, so make sure [Caps Lock] is not on. If you are trying to access the Internet wirelessly, make sure the wireless settings in the wireless client are the same as the settings in the AP. Disconnect all the cables from your device, and follow the directions in the Quick Start Guide again. If the problem continues, contact your ISP. I cannot access the Internet anymore. I had access to the Internet (with the NBG2105), but my Internet connection is not available anymore. Check the hardware connections, and make sure the LEDs are behaving as expected. See the Quick Start Guide and Section 1.8.1 on page 17. Reboot the NBG2105. If the problem continues, contact your ISP. The Internet connection is slow or intermittent. There might be a lot of traffic on the network. Look at the LEDs, and check Section 1.8.1 on page 17. If the NBG2105 is sending or receiving a lot of information, try closing some programs that use the Internet, especially peer-to-peer applications. Check the signal strength. If the signal strength is low, try moving the NBG2105 closer to the AP if possible, and look around to see if there are any devices that might be interfering with the wireless network (for example, microwaves, other wireless networks, and so on). Reboot the NBG2105. If the problem continues, contact the network administrator or vendor, or try one of the advanced suggestions. Advanced Suggestion • Check the settings for QoS. If it is disabled, you might consider activating it. 17.5 Resetting the NBG2105 to Its Factory Defaults If you reset the NBG2105, you lose all of the changes you have made. The NBG2105 re-loads its default settings, and the password resets to 1234. You have to make all of your changes again. 124 NBG2105 User’s Guide Chapter 17 Troubleshooting You will lose all of your changes when you push the RESET button. To reset the NBG2105: Make sure the power LED is on. Press the RESET button for longer than five seconds to set the NBG2105 back to its factory-default configurations. If the NBG2105 restarts automatically, wait for the NBG2105 to finish restarting, and log in to the Web Configurator. The password is “1234”. If the NBG2105 does not restart automatically, disconnect and reconnect the NBG2105’s power. Then, follow the directions above again. 17.6 Wireless LAN Connections I cannot access the NBG2105 or ping any computer from the WLAN. Make sure the wireless LAN is enabled on the NBG2105 and the NBG2105 is working in Router, AP or WISP+UR mode. Make sure the wireless adapter on your computer is working properly. Make sure the wireless adapter installed on your computer is IEEE 802.11 compatible and supports the same wireless standard as the NBG2105. Make sure your computer (with a wireless adapter installed) is within the transmission range of the NBG2105. Check that both the NBG2105 and the wireless adapter on your computer are using the same wireless and wireless security settings. I cannot access the Web Configurator after I switched from router mode to another mode. When you change from router mode to another mode, your computer must have an IP address in the range between “192.168.1.3” and “192.168.1.254”. The management IP address of the NBG2105 in other modes is 192.168.1.2. NBG2105 User’s Guide 125 Chapter 17 Troubleshooting What 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. 126 NBG2105 User’s Guide A PPENDIX Pop-up Windows, JavaScript and Java Permissions In order to use the web configurator you need to allow: • Web browser pop-up windows from your device. • JavaScript (enabled by default). • Java permissions (enabled by default).
