Introduction Thank you for choosing the TD851W 150Mbps Wireless N ADSL2+ Modem Router. 1.1 Product Overview The device is designed to provide a simple and cost-effective ADSL Internet connection for a private Ethernet or IEEE 802.11n/ IEEE 802.11g/ IEEE 802.11b wireless network. The TD851W connects to an Ethernet LAN or computers via standard Ethernet ports. The ADSL connection is made using ordinary telephone line with standard connectors. Multiple workstations can be networked and connected to the Internet using a single Wide Area Network (WAN) interface and single global IP address. The advanced security enhancements, MAC Filter, IP/Port Filter, URL Filter and ACL can help to protect your network from potentially devastating intrusions by malicious agents from the outside of your network. Wizard of the Web-based Utility is supplied and friendly help messages are provided for the configuration. Network and Router management is done through the Web-based Utility which can be accessed through local Ethernet using any web browser. ADSL The TD851W supports full-rate ADSL2+ connectivity conforming to the ITU and ANSI specifications. In addition to the basic DMT physical layer functions, the ADSL2+ PHY supports dual latency ADSL2+ framing (fast and interleaved) and the I.432 ATM Physical Layer. Wireless In the most attentive wireless security, the Router provides multiple protection measures. It can be set to turn off the wireless network name (SSID) broadcast so that only stations that have the SSID can be connected. The Router provides wireless LAN 64/128-bit WEP encryption security, WPA-PSK/WPA2-PSK authentication, as well as TKIP/AES encryption security. 1.2 Main Features

Here you can configure the DHCP mode of your ADSL Router as None, DHCP Relay or DHCP Server. DHCP stands for Dynamic Host Control Protocol. The DHCP Server gives out IP addresses when a device is booting up and request an IP address to be logged on to the network. 24 TD851W 150Mbps Wireless N ADSL2+ Modem Router User Guide Figure 4-8
LAN IP Address: Displays the LAN IP address of the Modem Router
Subnet Mask: Displays the subnet mask of the Modem Router.
DHCP Mode: Options available are None, DHCP Relay and DHCP Server. 1) None: In this mode, the Modem Router will do nothing when the host requests an IP address by DHCP protocol. The screen will be shown as in Figure 4-9. Figure 4-9 2) DHCP Relay: In this mode, the Router will work as a DHCP Relay. A DHCP relay is a device that forwards DHCP data between computers that request IP addresses and the DHCP server that assigns the addresses. Each of the device's interfaces can be configured as a 25 TD851W 150Mbps Wireless N ADSL2+ Modem Router User Guide DHCP relay. In this mode, the DHCP requests from local PCs will be forwarded to the DHCP server running on WAN side. Figure 4-10 Relay Server: Enter the IP Address of the DHCP server running on WAN side. 3) DHCP Server: Select this mode, then the screen will be shown as in Figure 4-11. The Router will work as a DHCP Server; it becomes the default gateway for DHCP client connected to it. That device on your local network must be set as a DHCP client to obtain the IP address automatically. By default, the DHCP Server is enabled. Figure 4-11 IP Pool Range: Specify the start and end IP address for the DHCP server's IP assignment. The default start and end IP Address are 192.168.1.100 and 192.168.1.200 separately. Please note that both addresses should be smaller than 192.168.1.254. Default Gateway: The default gateway address. 26 TD851W 150Mbps Wireless N ADSL2+ Modem Router User Guide Max Lease Time: The time that the DHCP client is allowed to maintain the assigned dynamic IP. After the dynamic IP address has expired, the user will be automatically assigned a new one. The default is 1440 minutes. Domain Name: Specify a user-friendly name to refer to the group of hosts (subnet) that will be assigned addresses from this pool. DNS Servers: The IP address of DNS server used in option filed of DHCP message.

Fragment Threshold: This value specifies the maximum size for a packet before data is fragmented into multiple packets. If you experience a high packet error rate, you may slightly increase the Fragmentation Threshold. Setting the Fragmentation Threshold too low may result in poor network performance. Only minor reduction of the default value is recommended. In most cases, it should remain at its default value of 2346.
RTS Threshold: Should you encounter inconsistent data flow, only minor reduction of the default value 2347 is recommended. If a network packet is smaller than the preset RTS threshold size, the RTS/CTS mechanism will not be enabled. The Router sends Request to Send (RTS) frames to a particular receiving station and negotiates the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to acknowledge the right to begin transmission. In most cases, keep its default value of 2347.
Beacon Interval: Enter a value between 20-1000 milliseconds. The Beacon Interval value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the Router to synchronize the wireless network. The default value is 100.
DTIM Interval: This value, between 1 and 255, indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast messages. When the Router has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast and multicast messages. The default value is 1. 35 TD851W 150Mbps Wireless N ADSL2+ Modem Router User Guide
