    Information Protocol (RIP). Using RIP, routers periodically update one another and check for changes to add to the routing table. The MR814v2 router supports both the older RIP-1 and the newer RIP-2 protocols. Among other improvements, RIP-2 supports subnet and multicast protocols. RIP is not required for most home applications.
  • Page 93 The latter version is easier to remember and easier to enter into your computer. In addition, the 32 bits of the address are subdivided into two parts. The first part of the address identifies the network, and the second part identifies the host node or station on the network. The dividing point may vary depending on the address range and the application.

  • Page 94: Netmask

    • Class C Class C addresses can have 254 hosts on a network. Class C addresses use 24 bits for the network address and eight bits for the node. They are in this range: 192.0.1.x to 223.255.254.x. • Class D Class D addresses are used for multicasts (messages sent to many hosts).

  • Page 95: Subnet Addressing

    Reference Manual for the MR814v2 Cable/DSL Wireless Router As a shorter alternative to dotted-decimal notation, the netmask may also be expressed in terms of the number of ones from the left. This number is appended to the IP address, following a backward slash (/), as “/n.”...
  • Page 96 Although the preceding example uses the entire third octet for a subnet address, note that you are not restricted to octet boundaries in subnetting. To create more network numbers, you need only shift some bits from the host address to the network address. For instance, to partition a Class C network number (192.68.135.0) into two, you shift one bit from the host address to the network address.

The DHCP server of the MR814v2 router is preconfigured to automatically assign private addresses. Regardless of your particular situation, do not create an arbitrary IP address; always follow the guidelines explained here.

    Reference Manual for the MR814v2 Cable/DSL Wireless Router This scheme offers the additional benefit of firewall-like protection because the internal LAN addresses are not available to the Internet through the translated connection. All incoming inquiries are filtered out by the router. This filtering can prevent intruders from probing your system.

    Reference Manual for the MR814v2 Cable/DSL Wireless Router What is a Firewall? A firewall is a device that protects one network from another, while allowing communication between the two. A firewall incorporates the functions of the NAT router, while adding features for dealing with a hacker intrusion or attack.

    Ethernet Cabling Although Ethernet networks originally used thick or thin coaxial cable, most installations currently use unshielded twisted pair (UTP) cabling. The UTP cable contains eight conductors, arranged in four twisted pairs, and terminated with an RJ45 type connector. A normal straight-through UTP Ethernet cable follows the EIA568B standard wiring and pinout as described in Table 7-1.

    This chapter provides an overview of Wireless networking. Wireless Networking Overview The MR814v2 router conforms to the Institute of Electrical and Electronics Engineers (IEEE) 802.11b standard for wireless LANs (WLANs). On an 802.11b wireless link, data is encoded using direct-sequence spread-spectrum (DSSS) technology and is transmitted in the unlicensed radio spectrum at 2.5GHz.

  • Page 128: Ad Hoc Mode (Peer-To-Peer Workgroup

    Reference Manual for the MR814v2 Cable/DSL Wireless Router In the infrastructure mode, the wireless access point converts airwave data into wired Ethernet data, acting as a bridge between the wired LAN and wireless clients. Connecting multiple Access Points via a wired Ethernet backbone can further extend the wireless network coverage. As a mobile computing device moves out of the range of one access point, it moves into the range of another.

  • Page 129: Authentication And Wep

    The 802.11b standard defines several services that govern how two 802.11b devices communicate. The following events must occur before an 802.11b Station can communicate with an Ethernet network through an access point such as the one built in to the MR814v2: Turn on the wireless station.

  • Page 130: Open System Authentication

    • Shared Key Authentication requires that the station and the access point have the same WEP Key to authenticate. These two authentication procedures are described below. Open System Authentication The following steps occur when two devices use Open System Authentication: The station sends an authentication request to the access point.

  • Page 131: Overview Of Wep Parameters

    The station connects to the network. If the decrypted text does not match the original challenge text (i.e., the access point and station do not share the same WEP Key), then the access point will refuse to authenticate the station and the station will be unable to communicate with either the 802.11b network or Ethernet network.

Use WEP for Authentication and Encryption: A transmitting 802.11b device encrypts the data portion of every packet it sends using a configured WEP Key. The receiving 802.11b device decrypts the data using the same WEP Key. For authentication purposes, the 802.11b network uses Shared Key Authentication.
