Facilità d'uso
Domain Name Server (DNS) Address The DNS server is used to look up site addresses based on their names. •Get Automatically from ISP. Your ISP uses DHCP to assign your DNS servers. Your ISP automatically assigns this address. •Use These DNS Servers. If you know that your ISP does not automatically transmit DNS addresses to the wireless modem router during login, select this option, and enter the IP address of your ISP’s primary DNS server. If a secondary DNS server address is available, enter it also. NAT (Net Address Translation) NAT automatically assigns private IP addresses (10.1.1.x) to LAN-connected devices. •Enable. Usually NAT is enabled. •Disable. This disables NAT, but leaves the firewall active. Disable NAT only if you are sure that you do not require it. When NAT is disabled, only standard routing is performed by this router. Classical routing lets you directly manage the IP addresses that the wireless modem router uses. Classical routing should be selected only by experienced users1 1. Disabling NAT reboots the wireless modem router and resets its configuration settings to the factory defaults. Disable NAT only if you plan to install the wireless modem router in a setting where you will be manually administering the IP address space on the LAN side of the router. •Disable firewall. This disables the firewall in addition to disabling NAT. With the firewall disabled, the protections usually provided to your network are disabled. These fields appear only if no login is required. Router MAC Address The Ethernet MAC address that will be used by the wireless modem router on the Internet port. Some ISPs register the Ethernet MAC address of the network interface card in your computer when your account is first opened. They will then accept traffic only from the MAC address of that computer. This feature allows your wireless modem router to masquerade as that computer by “cloning” its MAC address. •Use Default Address. Use the default MAC address. •Use Computer MAC Address. The wireless modem router will capture and use the MAC address of the computer that you are now using. You must be using the one computer that is allowed by the ISP. •Use This MAC Address. Enter the MAC address that you want to use. Configuring ADSL Settings Note:For information about how to install ADSL filters, see the Setup Manual. NETGEAR recommends that you use the Setup Wizard to automatically detect and configure your ADSL settings. This usually works fine. However, if you have technical experience and are sure of the multiplexing method and virtual circuit number for the virtual path identifier (VPI) and virtual channel identifier (VCI), you can specify those settings here. Note:NETGEAR recommends using the Setup Wizard to select the correct country to optimize detection of the ADSL settings. If your ISP provided you with a multiplexing method or VPI/VCI number, then enter the setting: 1From the main menu, select ADSL Settings.The ADSL Settings screen displays. Figure 6. 2In the Multiplexing Method drop-down list, select LLC-based or VC-based. 3For the VPI, type a number between 0 and 255. The default is 8. 4For the VCI, type a number between 32 and 65535. The default is 35. 5Click Apply. 2. Configuring Your Wireless Network and Security Settings This chapter describes how to configure the wireless features of your N300 Wireless Gigabit ADSL2+ Modem Router DGN3500. For a wireless connection, the SSID, also called the wireless network name, and the wireless security setting must be the same for the modem router and wireless computers or wireless adapters. NETGEAR strongly recommends that you use wireless security. Computers can connect wirelessly at a range of several hundred feet. This can allow others outside of your immediate area to access your network. This chapter includes: •Planning Your Wireless Network •Manually Configuring Your Wireless Settings •Manually Configuring Your Wireless Security •Using Push 'N' Connect (WPS) to Configure Your Wireless Network •Connecting Additional Wireless Devices After WPS Setup Planning Your Wireless Network For compliance and compatibility between similar products in your area, the operating channel and region must be set correctly. To configure the wireless network, you can either specify the wireless settings, or you can use Wi-Fi Protected Setup (WPS) to automatically set the SSID and implement WPA/WPA2 security. •To manually configure the wireless settings, you must know the following: -SSID. The default SSID for the modem router is NETGEAR. -The wireless mode (802.11n, 802.11g, or 802.11b) that each wireless adapter supports. -Wireless security option. To successfully implement wireless security, check each wireless adapter to determine which wireless security option it supports. See Manually Configuring Your Wireless Security on page 21. •Push 'N' Connect (WPS) automatically implements wireless security on the modem router while, at the same time, allowing you to automatically impl...
