Troubleshooting

If your ISP provided a program to log you in to the Internet (such as WinPoET), you no longer
need to run that software after installing your router. You might need to go to Internet Explorer
and select
Tools > Internet Options
, click the Connections tab, and select
Never dial a
connection
.
Troubleshooting a Network Using the Ping Utility
Most network 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 network is
made very easy by using the ping utility in your computer or workstation.
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
Table 7-2 on
page 7-3
.

–
Check that the corresponding Link lights are on for your network interface card. 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 Wizard” on page 1-5
.
Problems with Date and Time
Under Content Filtering in the main menu, select
E-mail
to display a screen that shows the current
date and time of day. The WNR3500v2 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
Adjust for Daylight Savings Time
check box.
Wireless Connectivity
The first steps in solving wireless connection problems are these:
1.
Using your wireless card’s setup utility program, make sure that your wireless card can find
your wireless router.
2.
Configure and test with the simplest wireless connection possible, and then add security.
The topics in this section describe these steps.

Using Your Wireless Card Setup Program
When you install a NETGEAR wireless card 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.
If you have no specific wireless card setup program installed, you can use the basic setup utility in
Windows by following these steps:
1.
Open the Windows Control Panel, and double-click
Network Connections
.
2.
In the LAN section, double-click
Wireless Network Connection
.
Use the setup program to scan for available wireless networks. Look for a network name (SSID) of
NETGEAR or your custom SSID if you have changed it. If your wireless network does not appear,
check these conditions:
•
Is your router’s wireless radio enabled? See
“Manually Configuring Your Wireless Settings”
on page 2-4
.
•
Is your router’s SSID broadcast enabled? See
“Manually Configuring Your Wireless Settings”
on page 2-4
.
•
Is your router set to a wireless standard that is not supported by your wireless card? Check the
Mode setting as described in
“Manually Configuring Your Wireless Settings” on page 2-4
.
If your wireless network appears, but the signal strength is weak, check these conditions:
•
Is your router too far from your computer, or too close? Place your computer 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 computer? See
“Optimizing Wireless Performance” on page 6-5
.
If your wireless network appears and has good signal strength, configure your wireless card and
router for the simplest possible connection as described in the next section.
Setting Up and Testing Basic Wireless Connectivity
Note:
If you use a wireless computer to change wireless settings, you might be
disconnected when you click
Apply
. Reconfigure your wireless adapter to match
the new settings, or access the wireless router from a wired computer to make any
further changes.

Follow these instructions to set up and test basic wireless connectivity. Once you have established
basic wireless connectivity, you can enable security settings appropriate to your needs.
1.
Select
Wireless Settings
under Setup in the main menu of the WNR3500v2 router.
2.
For the wireless network name (SSID), use the default name, or choose a suitable descriptive
name. In the
Name (SSID)
field, you can enter a value of up to 32 alphanumeric characters.
The default SSID is NETGEAR.
3.
Select the region in which the wireless interface will operate.
4.
Set the channel. The default channel is
Auto
.
Figure 7-1
Note:
The SSID is case-sensitive; NETGEAR is not the same as nETgear. Also, the
SSID of any wireless access adapters must match the SSID you specify in the
WNR3500v2 router. If they do not match, you will not get a wireless
connection to the WNR3500v2 router.
