Reference Manual for the 54 Mbps Wireless Router with Phone Adapter WGR826V Lights Never Turn Off When the router is turned on, the lights turns on for about 10 seconds and then turn off. If all the lights stay on, there is a fault within the router. If all lights are still on one minute after power up: • Cycle the power to see if the router recovers. • Clear the router’s configuration to factory defaults. This will set the router’s IP address to 192.168.15.1.
Reference Manual for the 54 Mbps Wireless Router with Phone Adapter WGR826V • Make sure your computer’s IP address is on the same subnet as the router. If you are using the default addressing schemes, your computer’s address should be in the range of 192.168.15.2 to 192.168.15.253. Refer to “Verifying TCP/IP Properties” on page C-8 or “Verifying TCP/IP Properties for Macintosh Computers” on page C-19 to find your computer’s IP address. Follow the instructions in Appendix C to configure your computer.
Reference Manual for the 54 Mbps Wireless Router with Phone Adapter WGR826V 4. Check that an IP address is shown for the WAN Port If 0.0.0.0 is shown, your router has not obtained an IP address from your ISP. If your router is unable to obtain an IP address from the ISP, you may need to force your cable or DSL modem to recognize your new router by performing the following procedure: 1. Turn off power to the cable or DSL modem. 2. Turn off power to your router. 3.
Reference Manual for the 54 Mbps Wireless Router with Phone Adapter WGR826V A DNS server is a host on the Internet that translates Internet names (such as www addresses) to numeric IP addresses. Typically your ISP will provide the addresses of one or two DNS servers for your use. If you entered a DNS address during the router’s configuration, reboot your computer and verify the DNS address as described in “Install or Verify Windows Networking Components” on page C-9.
Reference Manual for the 54 Mbps Wireless Router with Phone Adapter WGR826V If the path is not functioning correctly, you could have one of the following problems: • Wrong physical connections — Make sure the LAN port LED is on.

Appendix B Network, Routing, and Firewall Basics This chapter provides an overview of IP networks, routing, and networking. Related Publications As you read this document, you may be directed to various RFC documents for further information. An RFC is a Request For Comment (RFC) published by the Internet Engineering Task Force (IETF), an open organization that defines the architecture and operation of the Internet.
Reference Manual for the 54 Mbps Wireless Router with Phone Adapter WGR826V Routers vary in performance and scale, number of routing protocols supported, and types of physical WAN connection they support. The WGR826V 54 Mbps Wireless Router with Phone Adapter is a small office router that routes the IP protocol over a single-user broadband connection. Routing Information Protocol One of the protocols used by a router to build and maintain a picture of the network is the Routing Information Protocol (RIP).
Reference Manual for the 54 Mbps Wireless Router with Phone Adapter WGR826V There are five standard classes of IP addresses. These address classes have different ways of determining the network and host sections of the address, allowing for different numbers of hosts on a network. Each address type begins with a unique bit pattern, which is used by the TCP/IP software to identify the address class.
Reference Manual for the 54 Mbps Wireless Router with Phone Adapter WGR826V • Class D Class D addresses are used for multicasts (messages sent to many hosts). Class D addresses are in this range: 224.0.0.0 to 239.255.255.255. • Class E Class E addresses are for experimental use. This addressing structure allows IP addresses to uniquely identify each physical network and each node on each physical network.
Reference Manual for the 54 Mbps Wireless Router with Phone Adapter WGR826V Subnet Addressing By looking at the addressing structures, you can see that even with a Class C address, there are a large number of hosts per network. Such a structure is an inefficient use of addresses if each end of a routed link requires a different network number. It is unlikely that the smaller office LANs would have that many devices. You can resolve this problem by using a technique known as subnet addressing.
Reference Manual for the 54 Mbps Wireless Router with Phone Adapter WGR826V Note: The number 192.68.135.127 is not assigned because it is the broadcast address of the first subnet. The number 192.68.135.128 is not assigned because it is the network address of the second subnet. The following table lists the additional subnet mask bits in dotted-decimal notation.
Reference Manual for the 54 Mbps Wireless Router with Phone Adapter WGR826V Table 8-2. Netmask Formats 255.255.255.252 /30 255.255.255.254 /31 255.255.255.255 /32 Configure all hosts on a LAN segment to use the same netmask for the following reasons: • So that hosts recognize local IP broadcast packets When a device broadcasts to its segment neighbors, it uses a destination address of the local network address with all ones for the host address.
Reference Manual for the 54 Mbps Wireless Router with Phone Adapter WGR826V Single IP Address Operation Using NAT In the past, if multiple computers on a LAN needed to access the Internet simultaneously, you had to obtain a range of IP addresses from the ISP. This type of Internet account is more costly than a single-address account typically used by a single user with a modem, rather than a router. The WGR826V Wireless Router employs an address-sharing method called Network Address Translation (NAT).
Reference Manual for the 54 Mbps Wireless Router with Phone Adapter WGR826V MAC Addresses and Address Resolution Protocol An IP address alone cannot be used to deliver data from one LAN device to another. To send data between LAN devices, you must convert the IP address of the destination device to its media access control (MAC) address. Each device on an Ethernet network has a unique MAC address, which is a 48-bit number assigned to each device by the manufacturer.
Reference Manual for the 54 Mbps Wireless Router with Phone Adapter WGR826V When a computer accesses a resource by its descriptive name, it first contacts a DNS server to obtain the IP address of the resource. The computer sends the desired message using the IP address. Many large organizations, such as ISPs, maintain their own DNS servers and allow their customers to use the servers to look up addresses.
Reference Manual for the 54 Mbps Wireless Router with Phone Adapter WGR826V 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. Several known types of intrusion or attack can be recognized when they occur.

Reference Manual for the 54 Mbps Wireless Router with Phone Adapter WGR826V The WGR826V Wireless Router incorporates Auto UplinkTM technology (also called MDI/ MDIX). Each LOCAL Ethernet port will automatically sense whether the Ethernet cable plugged into the port should have a normal connection (e.g. connecting to a computer) or an uplink connection (e.g. connecting to a router, switch, or hub). That port will then configure itself to the correct configuration.

Reference Manual for the 54 Mbps Wireless Router with Phone Adapter WGR826V Is WPA/WPA2 Perfect? WPA/WPA2 is not without its vulnerabilities. Specifically, it is susceptible to denial of service (DoS) attacks. If the access point receives two data packets that fail the message integrity code (MIC) within 60 seconds of each other, then the network is under an active attack, and as a result, the access point employs counter measures, which include disassociating each station using the access point.
Reference Manual for the 54 Mbps Wireless Router with Phone Adapter WGR826V Changes to Wireless Access Points Wireless access points must have their firmware updated to support the following: • • • • • The new WPA/WPA2 information element To advertise their support of WPA/WPA2, wireless APs send the beacon frame with a new 802.11 WPA/WPA2 information element that contains the wireless AP's security configuration (encryption algorithms and wireless security configuration information).
