Chapter 2: WEB Configuration 8. RIP (Routing Information Protocol) Setup This feature enables the gateway to be used in small business situations where more than one LAN (local area network) is installed. The RIP protocol provides the gateway a means to “advertise” available IP routes to these LANs to your cable operator, so packets can be routed properly in this situation. Your cable operator will advise you during installation if any setting changes are required here. Fig. 26 Gateway\Advanced\RIP Setup

Chapter 2: WEB Configuration Automatic Security Configuration Fig. 38 Automatic Security Configuration WiFi Protected Setup (WPS) is an easy and secure way of configuring and connecting your WiFi access point. In your case, the DWG875/DWG875T is the Access Point (AP), and Your PC (or Wifi Device) is called the STA. When configuring your Wifi Network via WPS, Messages are exchanged between the STA and AP in order to configure the Security Settings on both devices.
Chapter 2: WEB Configuration If you select “Push-Button”, then the WPS Add Client option will appear as shown below. Fig. 39 WPS/Push-Button And then if you click “Add” button then WPS Setup AP page will appear as shown in Fig.38 Fig. 40 WPS Setup AP/PUSH And WPS Configure Status will be “In progress”, after establishing the connection the WPS Configure Status will be “Success!” as shown below. After successful connection the client will get IP address from AP and then internet will be accessible. Fig.
Chapter 2: WEB Configuration If you select WPS Method to PIN then it will ask for PIN while configuring the WiFi AP by showing a text box so, you need to enter PIN to establish the connection. You can get the PIN from your connected Wi-Fi client. Fig. 42 WPS/PIN PIN: Use this option to set the PIN, enter 4-8 digits PIN of the device you wish to configure. After entering the pin click “Add” button, then the WPS Setup AP page will appear as shown in Fig.41 Fig.

Chapter 3: Networking Chapter 3: Networking Communications Data communication involves the flow of packets of data from one device to another. These devices include personal computers, Ethernet and USB hubs, cable modems, digital routers and switches, and highly integrated devices that combine functions, like the Wireless Cable Gateway. The gateway integrates the functionality often found in two separate devices into one.
Chapter 3: Networking can use to configure its networking side; when you communicate with the networking side, your communication is following this path. Each packet on the Internet addressed to a PC in your home travels from the Internet downstream on the cable company’s system to the WAN side of your Wireless Cable Gateway.
Chapter 3: Networking configured Ethernet address matches the Ethernet destination address inside the packet. Furthermore, at a packet’s final destination, its destination IP address must also match the IP address of the stack. Each packet that enters a device contains source MAC and IP addresses telling where it came from, and destination MAC and IP addresses telling where it is going to.
Chapter 3: Networking Fig. 55 Two IP stacks are activated in cable modem mode CM (Cable Modem) Mode provides basic home networking. In this mode, two IP stacks are active: • IP Stack 1 - for use by the cable company to communicate with the cable modem section only. This stack receives its IP address from the cable company during CM initialization. It uses the MAC address printed on the label attached to the Wireless Cable gateway.
Chapter 3: Networking Residential Gateway (RG) Mode Fig. 56 Residential Gateway Mode Fig. 57 Three IP stacks are activated in Residential mode RG (Residential Gateway) Mode provides basic home networking plus NAT (Network Address Translation). In this mode, three IP stacks are active: • IP Stack 1 - for use by the cable company to communicate with the Cable Modem section only. This stack receives its IP address from the cable company during CM initialization.
Chapter 3: Networking used by your cable company to deliver packets between the Internet and the gateway’s networking section so they can be routed to/from your PCs. This stack requires an IP address assigned by the cable company from their pool of available addresses. Your cable company may have you or your installer manually enter assigned addresses into your gateway, or use a DHCP Server to communicate them, or use a method that involves you entering host names.
