Troubleshoot Access to the Router Main Menu
If you are unable to access the router main menu from a computer on your local network,
check the following:
•
If you are using an Ethernet-connected computer, check the Ethernet connection
between the computer and the router as described in the previous section.
•
Make sure your computer’s IP address is on the same subnet as the router. If you are
using the recommended addressing scheme, your computer’s address should be in the
range of 192.168.0.2 to 192.168.0.254.
Note:
If your computer’s IP address is shown as 169.254.x.x:
Recent versions of Windows and Mac OS generate and assign an
IP address if the computer cannot reach a DHCP server. These
autogenerated addresses are in the range of 169.254.x.x. If your IP
address is in this range, check the connection from the computer to
the router, and reboot your computer.
•
If your router’s IP address was changed and you do not know the current IP address,
clear the router’s configuration to factory defaults. This action sets the router’s IP address
to www.routerlogin.net. This procedure is explained in
Restore the Default Configuration
and Password
on page 91.
•
Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using
Internet Explorer, click
Refresh
to be sure that the Java applet is loaded.
•
Try quitting the browser and launching it again.
•
Make sure that 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 management interface, check
the following:
•
When entering configuration settings, be sure to click the
Apply
button before moving to
another screen or tab, or your changes are lost.
•
Click the
Refresh
or
Reload
button in the web browser. The changes might have
occurred, but the web browser might be caching the old configuration.

Troubleshoot the ISP Connection
Check these possible sources of trouble if you are having difficulty connecting to or browsing
the Internet.
Connect to the Internet
If unable to connect to Internet, check the following:
1.
The Internet account is active.
If your ISP has provided you with a SIM card and you have not inserted it into the SIM
card slot on the back of the router yet, do so now.
2.
Wireless broadband coverage is available where the unit is located.
3.
Access the router main menu to verify that the broadband settings are correct. Check with
your ISP if you are unsure.
4.
Check the location of the router.
a.
Move the router closer to a window for better access to the Internet signal. A Signal
Quality LED that is off indicates no coverage.
b.
Maintain recommended minimum distances between NETGEAR equipment and
household appliances to reduce interference.

Troubleshoot Internet Browsing
If your router can obtain an IP address but your computer is unable to load any web pages
from the Internet:
•
The traffic meter is enabled, and the limit might have been reached.
By configuring the traffic meter not to block, you can resume Internet access. If you have
a usage limit, your ISP might charge you for the overage.
•
Your computer might 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 provides the addresses of one or
two DNS servers for your use. If you entered a DNS address during the router’s
configuration, reboot your computer and verify the DNS address. Alternatively, you can
configure your computer manually with DNS addresses, as explained in your operating
system documentation
.
•
Your computer might not have the router configured as its TCP/IP router.
If your computer obtains its information from the router by DHCP, reboot the computer,
and verify the router address.
Troubleshoot a TCP/IP Network Using the 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. You can
easily troubleshoot a TCP/IP network by using the ping utility in your computer.
Test 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 PC running Windows 95 or later:
1.
From the Windows toolbar, click 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
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 working correctly, you could have one of the following problems:
•
Wrong physical connections
-
Make sure that the LAN LED is on. If the LED is off, follow the instructions in
Connect to the Internet
on page 88.
-
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 computer or workstation.
-
Verify that the IP address for your router and your workstation are correct and that
the addresses are on the same subnet.
Test 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.
To test the path:
1.
From the Windows toolbar, click the
Start
button, and 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 DNS server.
If the path is functioning correctly, replies as in the previous section are displayed. When you
do not receive replies:
•
Check that your computer has the IP address of your router listed as the default router. If
the IP configuration of your computer gets assigned by DHCP, this information is not
visible in your computer’s Network Control Panel. Verify that the IP address of the router
is listed as the default router.
•
Make sure that the network address of your computer (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 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 only traffic 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 so, you need to configure your router to
clone or spoof the MAC address from the authorized computer.
