Testing the LAN Path to Your Router
You can ping the router from your computer to verify that the LAN path to your router is set up
correctly.
To ping the router from a running Windows PC:
1.
From the Windows toolbar, click Start, and then select
Run
.
2.
In the field provided, type
ping
followed by the IP address of the router, as in this example:
ping www.routerlogin.net
3.
Click
OK
.
You should see a message like this one:
Pinging <IP address > with 32 bytes of data
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
–
For a wired connection, make sure that the numbered LAN port light is on for the port
to which you are connected. If the light is off, follow the instructions in
“Troubleshooting Basic Functions” on page 7-2
.
–
Check that the appropriate LEDs are on for your network devices. If your router and
computer are connected to a separate Ethernet switch, make sure that the link lights
are on for the switch ports that are connected to your computer and router.
•
Wrong network configuration
–
Verify that the Ethernet card driver software and TCP/IP software are both installed
and configured on your computer.
–
Verify that the IP address for your router and your computer are correct and that the
addresses are on the same subnet.

Testing the Path from Your Computer to a Remote Device
After verifying that the LAN path works correctly, test the path from your computer to a remote
device.
1.
From the Windows toolbar, click the Start button, and then select
Run
.
2.
In the Windows Run window, 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 like those shown in the previous section are displayed.
If you do not receive replies:
•
Check that your computer has the IP address of your router listed as the default gateway. If the
IP configuration of your computer is assigned by DHCP, this information is not be visible in
your computer’s Network Control Panel. Verify that the IP address of the router is listed as the
default gateway as described in the online document you can access from
“Preparing Your
Network” in Appendix B
.
•
Check to see that the network address of your computer (the portion of the IP address specified
by the subnet mask) 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 computer, enter that host name as the account name
in the Basic Settings screen.
•
Your ISP could be rejecting the Ethernet MAC addresses of all but one of your computers.
Many broadband ISPs restrict access by allowing traffic only from the MAC address of your
broadband modem, but some ISPs additionally restrict access to the MAC address of a single
computer connected to that modem. If this is the case, you must configure your router to
“clone” or “spoof” the MAC address from the authorized computer. For more information, see
“Using the Setup Manual” on page 1-1
.
Problems with Date and Time
Select
E-mail
under Content Filtering in the main menu to display a screen that shows the current
date and time of day. The WNR2000v2 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 the
following:

•
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 correct. If you have just completed configuring the router, wait at
least 5 minutes, and check the date and time again.
•
Time is off by one hour.
Cause: The router does not adjust for daylight savings time. In the E-mail screen, select the
Automatically Adjust for Daylight Savings Time
check box.
Problems with Wireless Adapter Connections
If your wireless adapter is unable to connect, check its connection settings.
To check the adapter’s connection settings:
1.
open the adapter setup utility to check connections:
•
NETGEAR Smart Wizard utility
. If you installed a NETGEAR wireless adapter in your
computer, a Smart Wizard utility program is installed that can provide helpful information
about your wireless network. You can find this program in your Windows Program menu
or as an icon in your system tray. Other wireless card manufacturers might include a
similar program.
•
Windows basic setup utility
. If you have no specific wireless card setup program
installed, you can use the basic setup utility in Windows:
–
Open the Windows Control Panel, and double-click
Network Connections
.
–
In the LAN section, double-click
Wireless Network Connection
.
2.
Use the adapter’s setup program to scan for available wireless networks, looking for the
network name (SSID) of
NETGEAR
, or your custom SSID if you have changed it.
3.
If your wireless network appears and has good signal strength, configure and test with the
simplest wireless connection possible.
If your wireless network does not appear, check these conditions:
•
Is your router’s wireless radio enabled? See
“Viewing Advanced Wireless Settings” on
page 2-12
.
•
Is your router’s SSID broadcast enabled? See
“Viewing Advanced Wireless Settings” on
page 2-12
.
•
Is your router set to a wireless standard that is not supported by your wireless adapter? Check
the Mode setting as described in
“Viewing and Configuring Basic ISP Settings” on page 1-7
.

If your wireless network appears, but the signal strength is weak, check these conditions:
•
Is your router too far from your adapter, or too close? Place the computer that has the adapter
near the router, but at least 6 feet away, and see whether the signal strength improves.
•
Is your wireless signal obstructed by objects between the router and your adapter? See
“Optimizing Wireless Performance” on page 5-15
.
Restoring the Default Configuration and Password
This section explains how to restore the factory default configuration settings that reset the
router’s user name to
admin
, the password to
password
, and the IP address to
192.168.1.1
.
You can erase the current configuration and restore factory defaults in two ways:
•
Use the Erase function of the router. To use the Erase function, see
“Erasing the
Configuration” on page 6-9
.
•
Use the restore factory settings button on the rear panel of the router. Use this method for cases
when the administration password or IP address is not known.
To use the restore settings button:
1.
Locate the restore factory settings button on the rear panel of the router.
2.
Use a sharp object such as a pen or a paper clip to press and hold the restore factory settings
button for about 5 seconds, until the Power light begins to blink.
3.
Release the restore factory settings button, and wait for the router to restart, and for the Power
light to stop blinking and become solid green.
The factory default settings will be restored so that you can access the router from your Web
browser using the factory defaults.
If the wireless router fails to restart, or the Power light continues to blink or turns solid amber, the
unit might be defective. If the error persists, you might have a hardware problem and should
contact Technical Support at
.
Warning:
These procedures erase all current configuration settings.
