C HAPTER 23 Maintenance 23.1 Overview This chapter provides information on the Maintenance screens. 23.2 What You Can Do • Use the General screen to set the timeout period of the management session (Section 23.3 on page 166). • Use the Password screen to change your NBG6716’s system password (Section 23.4 on page 167). • Use the Time screen to change your NBG6716’s time and date (Section 23.5 on page 168). • Use the Firmware Upgrade screen to upload firmware to your NBG6716 (Section 23.6 on page 169).
Chapter 23 Maintenance The following table describes the labels in this screen. Table 68 Maintenance > General LABEL DESCRIPTION System Name System Name is a unique name to identify the NBG6716 in an Ethernet network. Domain Name Enter the domain name you want to give to the NBG6716. Administrator Inactivity Timer Type how many minutes a management session can be left idle before the session times out. The default is 5 minutes. After it times out you have to log in with your password again.
Chapter 23 Maintenance 23.5 Time Setting Screen Use this screen to configure the NBG6716’s time based on your local time zone. To change your NBG6716’s time and date, click Maintenance > Time. The screen appears as shown. Figure 120 Maintenance > Time The following table describes the labels in this screen. Table 70 Maintenance > Time LABEL DESCRIPTION Current Time and Date Current Time This field displays the time of your NBG6716.

Table 71 Maintenance > Firmware Upgrade LABEL DESCRIPTION File Path Type in the location of the file you want to upload in this field or click Browse... to find it. Browse... Click Browse... to find the .bin file you want to upload.
Chapter 23 Maintenance 23.7 Configuration Backup/Restore Screen Backup configuration allows you to back up (save) the NBG6716’s current configuration to a file on your computer. Once your NBG6716 is configured and functioning properly, it is highly recommended that you back up your configuration file before making configuration changes. The backup configuration file will be useful in case you need to return to your previous settings.
Chapter 23 Maintenance Table 72 Maintenance > Backup/Restore (continued) LABEL DESCRIPTION Upload Click Upload to begin the upload process. Note: Do not turn off the NBG6716 while configuration file upload is in progress. After you see a “configuration upload successful” screen, you must then wait one minute before logging into the NBG6716 again. The NBG6716 automatically restarts in this time causing a temporary network disconnect.
Chapter 23 Maintenance Figure 125 Maintenance > Language 23.10 System Operation Mode Overview The Sys OP Mode (System Operation Mode) function lets you configure your NBG6716 as a router or access point. You can choose between Router Mode, and Access Point Mode depending on your network topology and the features you require from your device. The following describes the device modes available in your NBG6716. Router A router connects your local network with another network, such as the Internet.
Chapter 23 Maintenance Figure 127 Access Point Mode 23.11 Sys OP Mode Screen Use this screen to select how you want to use your NBG6716. Figure 128 Maintenance > Sys OP Mode The following table describes the labels in the General screen. Table 73 Maintenance > Sys OP Mode LABEL DESCRIPTION Configuration Mode Router Mode Select Router Mode if your device routes traffic between a local network and another network such as the Internet. This mode offers services such as a firewall or bandwidth management.
Chapter 23 Maintenance Table 73 Maintenance > Sys OP Mode (continued) LABEL DESCRIPTION Access Point Mode Select Access Point Mode if your device bridges traffic between clients on the same network. • • • • • In Access Point Mode, all Ethernet ports have the same IP address. All ports on the rear panel of the device are LAN ports, including the port labeled WAN. There is no WAN port. The DHCP server on your device is disabled.
C HAPTER 24 Troubleshooting 24.1 Overview This chapter offers some suggestions to solve problems you might encounter. The potential problems are divided into the following categories. • Power, Hardware Connections, and LEDs • NBG6716 Access and Login • Internet Access • Resetting the NBG6716 to Its Factory Defaults • Wireless Connections • USB Device Problems • ZyXEL Share Center Utility Problems 24.2 Power, Hardware Connections, and LEDs The NBG6716 does not turn on. None of the LEDs turn on.
Chapter 24 Troubleshooting 4 Disconnect and re-connect the power adaptor to the NBG6716. 5 If the problem continues, contact the vendor. 24.3 NBG6716 Access and Login I don’t know the IP address of my NBG6716. 1 The default IP address of the NBG6716 in Router Mode is 192.168.1.1. The default IP address of the NBG6716 in Access Point Mode is 192.168.1.2.
Chapter 24 Troubleshooting 2 Check the hardware connections, and make sure the LEDs are behaving as expected. See the Quick Start Guide. 3 Make sure your Internet browser does not block pop-up windows and has JavaScript and Java enabled. See Appendix A on page 184. 4 Make sure your computer is in the same subnet as the NBG6716. (If you know that there are routers between your computer and the NBG6716, skip this step.
Chapter 24 Troubleshooting 1 Check the hardware connections, and make sure the LEDs are behaving as expected. See the Quick Start Guide. 2 Go to Maintenance > Sys OP Mode. Check your System Operation Mode setting. • If the NBG6716 is in Router Mode, make sure the WAN port is connected to a broadband modem or router with Internet access. Your computer and the NBG6716 should be in the same subnet.
Chapter 24 Troubleshooting • Check the settings for QoS. If it is disabled, you might consider activating it. 24.5 Resetting the NBG6716 to Its Factory Defaults If you reset the NBG6716, you lose all of the changes you have made. The NBG6716 re-loads its default settings, and the password resets to 1234. You have to make all of your changes again. You will lose all of your changes when you push the RESET button. To reset the NBG6716: 1 Make sure the power LED is on.
Chapter 24 Troubleshooting 7 Make sure you allow the NBG6716 to be remotely accessed through the WLAN interface. Check your remote management settings. • See the chapter on Wireless LAN in the User’s Guide for more information. I set up URL keyword blocking, but I can still access a website that should be blocked. Make sure that you select the Enable URL Keyword Blocking check box in the Content Filtering screen. Make sure that the keywords that you type are listed in the Keyword List.
Chapter 24 Troubleshooting • 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. 24.7 USB Device Problems I cannot access or see a USB device that is connected to the NBG6716. 1 Disconnect the problematic USB device, then reconnect it to the NBG6716.
Chapter 24 Troubleshooting 5 If the USB device requires a special driver, install the driver from the installation disc that came with the device. After driver installation, reconnect the USB device to the NBG6716 and try to connect to it again with your computer. 6 If the problem persists, contact your vendor. I cannot install the ZyXEL Share Center Utility. 1 Make sure that the set up program is one required for your operating system.
