DOCSIS The Data Over Cable Service Interface Specification (DOCSIS) is a telecommunications standard that defines the provision of data services) Internet access) over a traditional cable TV (CATV) network. Your CGN supports DOCSIS version 3.0. 3.1.2 IP ADDRESSES AND SUBNETS Every computer on the Internet must have a unique Internet Protocol (IP) address.
Local Area Network (LAN) and Wireless Local Area Network (WLAN), if enabled. You are free to assign IP addresses to computers on the LAN and WLAN manually, or to allow the CGN to assign them automatically via DHCP (Dynamic Host Configuration Protocol). IANA has reserved the following blocks...
HITRON CGN USER’S GUIDE If you assign addresses manually, they must be within the CGN’s LAN subnet. 184.108.40.206 SUBNETS A subnet (short for sub-network) is, as the name suggests, a separate section of a network, distinct from the main network of which it is a part. A subnet may contain all of the computers at one corporate local office, for example, while the main network includes several offices.
By default, the CGN is a DHCP client on the WAN (the CATV connection). It broadcasts an IP address over the cable network, and receives one from the service provider. By default, the CGN is a DHCP server on the LAN; it provides IP addresses to computers on the LAN which request them.
(or other device). For example, if a single computer has an Ethernet card (to connect to your CGN via one of the LAN ports) and also has a wireless card (to connect to your CGN over the wireless interface) the MAC addresses of the two cards will be different.
Internet from the service provider’s server, which specifies the settings that the CGN should use. It contains a variety of settings that are not present in the user-configurable Graphical User Interface (GUI) and can be specified only by the service provider.

7.1.1 WIRELESS NETWORKING BASICS Your CGN’s wireless network is part of the Local Area Network (LAN), known as the Wireless LAN (WLAN). The WLAN is a network of radio links between the CGN and the other computers and devices that connect to it.
The wireless clients connect to the access point in order to receive a wireless connection to the WAN and the wired LAN. The CGN is the access point, and the computers you connect to the CGN are the wireless clients.
(signal scrambling so that only authenticated users can decode the transmitted data). The sophistication of each security method varies, as does its effectiveness. The CGN supports the following wireless security protocols (in order of effectiveness): WEP (the Wired Equivalency Protocol): this protocol uses a series of “keys” or data strings to authenticate the wireless client with the AP, and to encrypt data sent over the wireless link.
THE BASIC SETTINGS SCREEN Use this screen to configure your CGN’s basic wireless settings. You can turn the wireless module on or off, select the wireless mode and channel, configure the wireless network’s SSID.
