Troubleshooting the Web Configuration Interface
If you are unable to access the router’s Web Configuration interface from a PC on your local
network, check the following:
•
Check the Ethernet connection between the PC and the router as described in the previous
section.
•
Make sure your PC’s IP address is on the same subnet as the router. If you are using the
recommended addressing scheme, your PC’s address should be in the range of 192.168.0.2 to
192.168.0.254. Refer to
“Verifying TCP/IP Properties” on page 4-5
or
“Verifying TCP/IP
Properties (Macintosh)” on page 4-8
to find your PC’s IP address. Follow the instructions in
Chapter 4
to configure your PC.
Note:
If your PC’s IP address is shown as 169.254.x.x: 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 connection from the PC to the router and reboot your PC.
•
If your router’s IP address has been changed and you don’t know the current IP address, clear
the router’s configuration to factory defaults. This will set the router’s IP address to
192.168.0.1. This procedure is explained in
“Restoring the Default Configuration and
Password” on page 6-7
.
•
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.
•
Try quitting the browser and launching it again.
•
Make sure you are using the correct login information. The factory default login name is
admin
and the password is
password
. Make sure that CAPS LOCK is off when entering this
information.
If the router does not save changes you have made in the Web Configuration Interface, check the
following:
•
When entering configuration settings, be sure to click the APPLY button before moving to
another menu or tab, or your changes are lost.
•
Click the Refresh or Reload button in the Web browser. The changes may have occurred, but
the Web browser may be caching the old configuration.

Troubleshooting
Troubleshooting the ISP Connection
If your router is unable to access the Internet, you should first determine whether the router is able
to obtain a WAN IP address from the ISP. Unless you have been assigned a static IP address, your
router must request an IP address from the ISP. You can determine whether the request was
successful using the Web Configuration Manager.
To check the WAN IP address:
1.
Launch your browser and select an external site such as www.netgear.com
2.
Access the Main Menu of the router’s configuration at http://192.168.0.1
3.
Under the Maintenance heading, select Router Status
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.
Wait five minutes and reapply power to the cable or DSL modem.
4.
When the modem’s LEDs indicate that it has reacquired sync with the ISP, reapply power to
your router.
If your router is still unable to obtain an IP address from the ISP, the problem may be one of the
following:
•
Your ISP may require a login program.
Ask your ISP whether they require PPP over Ethernet (PPPoE) or some other type of login.
•
If your ISP requires a login, you may have incorrectly set the login name and password.
•
Your ISP may check for your PC's host name.
Assign the PC Host Name of your ISP account as the Account Name in the Basic Settings
menu.
•
Your ISP only allows one Ethernet MAC address to connect to Internet, and may check for
your PC’s MAC address. In this case:
Inform your ISP that you have bought a new network device, and ask them to use the router’s
MAC address.

OR
Configure your router to spoof your PC’s MAC address. This can be done in the Basic Settings
menu. Refer to
“Manually Configuring Your Internet Connection” on page 2-16
.
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. If you entered a DNS address during the router’s configuration, reboot
your PC and verify the DNS address as described in
“Verifying TCP/IP Properties” on page
4-5
. Alternatively, you may configure your PC manually with DNS addresses, as explained in
your operating system documentation
.
•
Your PC may not have the router configured as its TCP/IP gateway.
If your PC obtains its information from the router by DHCP, reboot the PC and verify the
gateway address as described in
“Verifying TCP/IP Properties” on page 4-5
.
Troubleshooting a TCP/IP Network Using a Ping Utility
Most TCP/IP terminal devices and routers contain a ping utility that sends an echo request packet
to the designated device. The device then responds with an echo reply. Troubleshooting a TCP/IP
network is made very easy by using the ping utility in your PC or workstation.
Testing the LAN Path to Your Router
You can ping the router from your PC to verify that the LAN path to your router is set up correctly.
To ping the router from a PC running Windows 95 or later:
1.
From the Windows toolbar, click on the Start button and select Run.
2.
In the field provided, type Ping followed by the IP address of the router, as in this example:
3.
Click on OK.
You should see a message like this one:
Pinging <IP address> with 32 bytes of data
Page 74 / 121
Reference Manual for the Model RP614 v2 Web Safe Router

Troubleshooting
If the path is working, you see this message:
Reply from < IP address >: bytes=32 time=NN ms TTL=xxx
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 port LED is on. If the LED is off, follow the instructions in
“LAN
or WAN Port LEDs Not On
” on
page 6-2
.
—
Check that the corresponding Link LEDs are on for your network interface card and
for the hub ports (if any) that are connected to your workstation and router.
•
Wrong network configuration
—
Verify that the Ethernet card driver software and TCP/IP software are both installed
and configured on your PC or workstation.
—
Verify that the IP address for your router and your workstation are correct and that the
addresses are on the same subnet.
Testing the Path from Your PC to a Remote Device
After verifying that the LAN path works correctly, test the path from your PC to a remote device.
From the Windows run menu, type:
PING -n 10
<
IP address
>
where <
IP address
> is the IP address of a remote device such as your ISP’s DNS server.
If the path is functioning correctly, replies as in the previous section are displayed. If you do not
receive replies:
—
Check that your PC has the IP address of your router listed as the default gateway. If the IP
configuration of your PC is assigned by DHCP, this information will not be visible in your
PC’s Network Control Panel. Verify that the IP address of the router is listed as the default
gateway as described in
“Verifying TCP/IP Properties” on page 4-5
.
—
Check to see that the network address of your PC (the portion of the IP address specified
by the netmask) is different from the network address of the remote device.
—
Check that your cable or DSL modem is connected and functioning.

—
If your ISP assigned a host name to your PC, enter that host name as the Account Name in
the Basic Settings menu.
—
Your ISP could be rejecting the Ethernet MAC addresses of all but one of your PCs. Many
broadband ISPs restrict access by only allowing traffic from the MAC address of your
broadband modem, but some ISPs additionally restrict access to the MAC address of a
single PC connected to that modem. If this is the case, you must configure your router to
“clone” or “spoof” the MAC address from the authorized PC. Refer to
“Manually
Configuring Your Internet Connection” on page 2-16
.
Restoring the Default Configuration and Password
This section explains how to restore the factory default configuration settings, changing the
router’s administration password to
password
and the IP address to 192.168.0.1. You can erase the
current configuration and restore factory defaults in two ways:
•
Use the Erase function of the router (see
“Erasing the Configuration” on page 4-8
).
•
Use the Default Reset button on the rear panel of the router. Use this method for cases when
the administration password or IP address is not known.
To restore the factory default configuration settings without knowing the administration password
or IP address, you must use the Default Reset button on the rear panel of the router.
1.
Press and hold the Default Reset button until the Test LED turns on (about 10 seconds).
2.
Release the Default Reset button and wait for the router to reboot.
Problems with Date and Time
The E-Mail menu in the Content Filtering section displays the current date and time of day. The
RP614 v2 router uses the Network Time Protocol (NTP) to obtain the current time from one of
several Network Time Servers on the Internet. Each entry in the log is stamped with the date and
time of day. Problems with the date and time function can include:
•
Date shown is January 1, 2000. Cause: The router has not yet successfully reached a Network
Time Server. Check that your Internet access settings are configured correctly. If you have just
completed configuring the router, wait at least five minutes and check the date and time again.
•
Time is off by one hour. Cause: The router does not automatically sense Daylight Savings
Time. In the E-Mail menu, check or uncheck the box marked “Adjust for Daylight Savings
Time”.
