Chapter 11 Troubleshooting This chapter gives information about troubleshooting your Model RP114 Web Safe Router. After each problem description, instructions are provided to help you diagnose and solve the problem. Basic Functioning After you turn on power to the router, the following sequence of events should occur: • The PWR LED lights. • The router performs a self-test for 30 seconds, during which the Test LED should blink at a rate of about 0.5 Hz and then turn off.
Reference Guide for the Model RP114 Web Safe Router Test LED Never Blinks or LED Stays On When the router is turned on, the Test LED blinks for about 30 seconds at a rate of approximately 0.5 Hz and then turns off. If the Test LED does not blink, or if it stops blinking and stays on, there is a fault within the router. If you experience problems with the Test LED: • Cycle the power to see if the router recovers and the LED blinks for the correct amount of time.
Reference Guide for the Model RP114 Web Safe Router Note: Recent versions of Windows and MacOS will generate and assign an IP address if the computer cannot reach a DHCP server. These auto-generated addresses are in the range of 169.254.x.x. If your IP address is in this range, check the Ethernet connection from the PC to the router and reboot your PC. • Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet Explorer, click Refresh to be sure the Java applet is loaded.
Reference Guide for the Model RP114 Web Safe Router To check the WAN IP address from the Manager interface: 1. If your system uses a login script such as PPPoE or RoadRunner, go to Manager interface Menu 24.4 - System Maintenance - Diagnostic and select Internet Setup Test. This will cause your router to attempt to login to the ISP. 2. Go to Manager interface Menu 24.1 - System Maintenance - Status 3. Check that an IP address is shown for the WAN Port If 0.0.0.
Reference Guide for the Model RP114 Web Safe Router If your router can obtain an IP address, but your PC is unable to load any web pages from the Internet: • Your PC may not recognize any DNS server addresses. 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.
Reference Guide for the Model RP114 Web Safe Router If the path is not working, you see this message: Request timed out If the path is not functioning correctly, you could have one of the following problems: • Wrong physical connections — Make sure the LAN LNK/ACT LED is on.

Appendix B Network and Routing Basics This chapter provides an overview of IP networks and routing. Basic Router Concepts Large amounts of bandwidth can be provided easily and relatively inexpensively in a local area network (LAN). However, providing high bandwidth between a local network and the Internet can be very expensive. Because of this expense, Internet access is usually provided by a slower-speed wide-area network (WAN) link such as a cable or DSL modem.
Reference Guide for the Model RP114 Web Safe Router Routers vary in performance and scale, number of routing protocols supported, and types of physical WAN connection they support. The Model RP114 Web Safe Router 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 Guide for the Model RP114 Web Safe Router 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. After the address class has been determined, the software can correctly identify the host section of the address.
Reference Guide for the Model RP114 Web Safe Router • 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 Guide for the Model RP114 Web Safe Router 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 Guide for the Model RP114 Web Safe Router 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. To use the table, write down the original class netmask and replace the 0 value octets with the dotted-decimal value of the additional subnet bits.
Reference Guide for the Model RP114 Web Safe Router Table B-2. Netmask Formats 255.255.255.252 /30 255.255.255.254 /31 255.255.255.255 /32 NETGEAR strongly recommends that you 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 Guide for the Model RP114 Web Safe Router Single IP Address Operation Using NAT In the past, if multiple PCs 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 Model RP114 router employs an address-sharing method called Network Address Translation (NAT).
Reference Guide for the Model RP114 Web Safe 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. However, using port forwarding, you can allow one PC (for example, a Web server) on your local network to be accessible to outside users.
Reference Guide for the Model RP114 Web Safe Router IP Configuration by DHCP When an IP-based local area network is installed, each PC must be configured with an IP address. If the PCs need to access the Internet, they should also be configured with a gateway address and one or more DNS server addresses. As an alternative to manual configuration, there is a method by which each PC on the network can automatically obtain this configuration information.
