Changes Not Saved

If the router does not save the changes you make through the NETGEAR genie screens, check the following:

•

When you enter configuration settings on a screen, always click the

Apply

button before you move 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 old settings might be in the web browser’s cache.

Wireless Connectivity

If you are having trouble connecting wirelessly to the router, try to isolate the problem by checking the following:

•

Does the wireless device or computer that you are using find your wireless network?

If not, check the WiFi LED on the front of the router. If it is not lit, you can press the

WiFI

On/Off

button on the front of the router to turn the router’s wireless radio back on.

If you disabled the router’s SSID broadcast, your wireless network is hidden and does not display in your wireless client’s scanning list. By default, SSID broadcast is enabled.

•

Does your wireless device support the security that you are using for your wireless network (WEP, WPA, or WPA2)?

•

If you want to view the wireless settings, select

BASIC > Wireless Settings

. For more information, see

Basic Wireless Settings

on page 28.

If your wireless device finds your network, 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 (2 meters) away, and see whether the signal strength improves.

•

Is your wireless signal blocked by objects between the router and your computer?

Troubleshoot Your 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. You can troubleshoot a network by using the ping utility on your computer or workstation.

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 computer running Windows:

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:

ping www.routerlogin.net

3.

Click the

OK

button.

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 might have one of the following problems:

•

Wrong physical connections

For a wired connection, make sure that the numbered Ethernet port LED is lit for the port to which you are connected.

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 LEDs are lit 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.

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.

1.

From the Windows toolbar, click the

Start

button and select

Run

.

2.

In the field provided, 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 like those examples shown in

Test the LAN Path to

Your Router

on page 84 are displayed.

If you do not receive replies, try the following:

•

Check that your computer has the IP address of your router listed as the default gateway.

If a DHCP server assigns the IP configuration of your computer, this information is not visible on your computer’s Network Control Panel. Verify that the IP address of the router is listed as the default gateway.

•

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 broadband 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 Internet Settings screen.

•

Your ISP might 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, configure your router to clone or spoof the MAC address from the authorized computer.
