Reference Guide for the Model RP114 Web Safe Router
Troubleshooting 11-5
If yourrouter can obtain an IP address, but your PC is unable to load any web pages from the
Internet:
• YourPC may not recognize any DNS server addresses.
A DNS serveris a host on the Internet that translates Internet names (such as www addresses)
to numericIP addresses. Typically your ISP will provide the addressesof one or two DNS
serversfor your use. If you entered a DNS address during the router’s configuration, reboot
yourPC and verify the DNS address as described in “VerifyingTCP/IP Properties (Windows)“
on page 3-4. Alternatively,you may configure your PC manually with DNS addresses, as
explainedin your operating system documentation.
• YourPC may not have the router configured as its TCP/IP gateway.
If your PC obtains itsinformation from the router by DHCP, reboot the PC and verify the
gateway addressas described in “Verifying TCP/IP Properties (Windows)“on page 3-4.
Troubleshooting a TCP/IP Network Using a Ping Utility
Most TCP/IP terminaldevices and routers contain a ping utility that sends an echo request packet
to the designateddevice. The device then responds with an echo reply.Troubleshooting a TCP/IP
network is made very easy by using the ping utility in the built-in Mana ger interface (Menu 24.4)
or in yourPC or workstation.

Testing the LAN Path to YourRouter

Youcan ping the router from your PC to verify that the LAN path to your router is set up correctly.
Toping the router from a PC running Windows 95 or later:
1. Fromthe Windowstoolbar, click on the Start button and select Run.
2. In the fieldprovided, type Ping followed by the IP address of the router,as in this
example:
ping 192.168.0.1
3. ClickonOK.
Youshould see a message like this one:
Pinging <IP address> with 32 bytes of data
If thepath is working, you see this message:
Reply from < IP address >: bytes=32 time=NN ms TTL=xxx
