Internet Setup If you consider yourself an advanced user and have configured a router before, click Add to add a new Internet Setup and input all the settings manually. Wireless Setting The wireless section is used to configure the wireless settings for your D-Link router. Note that changes made in this section may also need to be duplicated on wireless clients that you want to connect to your wireless network. To protect your privacy, use the wireless security mode to configure the wireless security features. Wireless Wizard If you are new to wireless networking, click on Wireless Wizard and the router will guide you through a few simple steps to get your wireless network up and running. Wireless Basics Basic settings to get your wireless network up and running. Enable Wireless This option turns off and on the wireless connection feature of the router. When you set this option, the following parameters are in effect. Wireless Network Name (SSID) When you are browsing for available wireless networks, this is the name that will appear in the list (unless Access Point is set to Hidden, see below). For security purposes, it is highly recommended to change from the pre-configured network name. Visibility Status Allows you to hide your wireless network. When this option is set to Visible, your wireless network name is broadcast to anyone within the range of your signal. If you're not using encryption then they could connect to your network. When Invisible mode is enabled, you must enter the Wireless Network Name (SSID) on the client manually to connect to the network. Country This is used to identify the available wireless channel for your country. In case your country is not in the list, please select the country nearest to you. Wireless Channel 802.11b and 802.11g use channels to limit interference from other devices. If you are experiencing interference with another 2.4Ghz device such as a baby monitor, security alarm, or cordless phone, then change the channel on your router. 802.11 Mode Select Mixed 802.11g and 802.11b to operate in b/g mode. Or select specified mode to use. Wireless Security Settings to secure your wireless network Security Mode Unless one of these encryption modes is selected, wireless transmissions to and from your wireless network can be easily intercepted and interpreted by unauthorized users. WEP A method of encrypting data for wireless communication intended to provide the same level of privacy as a wired network. WEP is not as secure as WPA encryption. To gain access to a WEP network, you must know the key. The key is a string of characters that you create. When using WEP, you must determine the level of encryption. The type of encryption determines the key length. 128-bit encryption requires a longer key than 64-bit encryption. Keys are defined by entering in a string in HEX (hexadecimal - using characters 0-9, A-F) or ASCII (American Standard Code for Information Interchange - alphanumeric characters) format. ASCII format is provided so you can enter a string that is easier to remember. The ASCII string is converted to HEX for use over the network. Four keys can be defined so that you can change keys easily. Example: 64-bit hexadecimal keys are exactly 10 characters in length. (12345678FA is a valid string of 10 characters for 64-bit encryption.) 128-bit hexadecimal keys are exactly 26 characters in length. (456FBCDF123400122225271730 is a valid string of 26 characters for 128-bit encryption.) 64-bit ASCII keys are up to 5 characters in length (DMODE is a valid string of 5 characters for 64-bit encryption.) 128-bit ASCII keys are up to 13 characters in length (2002HALOSWIN1 is a valid string of 13 characters for 128-bit encryption.) Auto (WPA or WPA2) (Wi-Fi Protected Access). Uses TKIP or AES encryption Method. This is useful during transitional times for upgrades in the enterprise environment, this mixed authentication method allows "upgraded" and users not yet "upgraded" to access the network via the router. WPA Only Uses TKIP (Temporal Key Integrity Protocol) encryption (instead of WEP encryption which is disabled). WPA2 Only Uses AES (Advanced Encryption Standard) instead of TKIP as its encryption method. WPA Mode WPA-PSK (Wi-Fi Protected Access - Pre-Shared Key) - WPA for home and SOHO environments, using AES or TKIP encryption, per-packet key construction, and key management that WPA provides in the enterprise environment. The main difference is that the password is entered manually. A group re-key interval time is also required. WPA-Enterprise (Wi-Fi Protected Access - Enterprise) - usually used for the larger Enterprise environment. RADIUS server information must be entered for WPA as well as a group re-key interval time Group Key Update Interval: The amount of time before the group key used for broadcast and multicast data is changed. Authentication Timeout: Amount of time before a client will be required to re-authenticate. RADIUS Server IP Address: The IP address of the authentication server. RADIUS Server Port: The port number used to connect to the authentication server. RADIUS Server Shared Secret: A passphrase that must match with the authentication server. Wireless WPS Wireless WPS is guiding you to reset the WPS to unconfigured, the "wireless settings" will be reset to factory default, other settings will remain unchanged. Local Network LAN Setup These are the settings of the LAN (Local Area Network) interface for the router. The router's local network (LAN) settings are configured based on the IP Address and Subnet Mask assigned in this section. The IP address is also used to access this Web-based management interface. It is recommended that you use the default settings if you do not have an existing network. Router IP Address The IP address of your router on the local area network. Your local area network settings are based on the address assigned here. For example, Subnet Mask The subnet mask of your router on the local area network. DHCP Server Settings DHCP stands for Dynamic Host Configuration Protocol. The DHCP section is where you configure the built-in DHCP Server to assign IP addresses to the computers and other devices on your local area network (LAN). Enable DHCP Server Once your D-Link router is properly configured and this option is enabled, the DHCP Server will manage the IP addresses and other network configuration information for computers and other devices connected to your Local Area Network. There is no need for you to do this yourself. The computers (and other devices) connected to your LAN also need to have their TCP/IP configuration set to "DHCP" or "Obtain an IP address automatically". When you set Enable DHCP Server , the following options are displayed. DHCP IP Address Range These two IP values ( from and to ) define a range of IP addresses that the DHCP Server uses when assigning addresses to computers and devices on your Local Area Network. Any addresses that are outside of this range are not managed by the DHCP Server; these could, therefore, be used for manually configured devices or devices that cannot use DHCP to obtain network address details automatically. Your D-Link router, by default, has a static IP address of This means that addresses to can be made available for allocation by the DHCP Server. Example: Your D-Link router uses for the IP address. You've assigned a computer that you want to designate as a Web server with a static IP address of You've assigned another computer that you want to designate as an FTP server with a static IP address of Therefore the starting IP address for your DHCP IP address range needs to be or greater. Example: Suppose you configure the DHCP Server to manage addresses From To This means that to and to are NOT managed by the DHCP Server. Computers or devices that use addresses from these ranges are to be manually configured. DHCP Lease Time The amount of time that a computer may have an IP address before it is required to renew the lease. The lease functions just as a lease on an apartment would. The initial lease designates the amount of time before the lease expires. If the tenant wishes to retain the address when the lease is expired then a new lease is established. If the lease expires and the address is no longer needed then another tenant may use the address. DHCP RESERVATIONS It's used for binding your MAC Address and a static IP Address together. And therefore,the IP Address must be in the DHCP Address pool.The MAC Address will never change unless you do something to change it,so your lan IP will not change either. Tips: The format of MAC Address is xx:xx:xx:xx:xx:xx. Example: 00:22:33:AA:BB:CC Time and Date The Time Configuration option allows you to configure, update, and maintain the correct time on the router's internal system clock. From this section you can set the time zone that you are in and set the Time Server. Current Router Time Displays the time currently maintained by the router. If this is not correct, use the following options to configure the time correctly. Automatically synchronize with Internet Time servers Select this option if you want to synchronize the router's clock to a Network Time Server over the Internet. If you are using schedules or logs, this is the best way to ensure that the schedules and logs are kept accurate. NTP Time Server Select a Network Time Server for synchronization. You can type in the address of a time server or select one from the list. If you have trouble using one server, select another. Time Zone Select your local time zone from pull down menu. Print Server Print Server allow you connect a printer to CPE. Printer name : shared name. Name and Model: such as 'HP LaserJet 1020'.   Copyright 2008-2011 D-Link Systems, Inc.
