PPPoE
In the IPv6 screen, when you select
PPPoE
from the drop-down list, the following screen
displays.
The following fields are included in this screen:
Login
. This is usually the name that you use in your email address. For example, if your main
mail account is [email protected], then you would put JerAB in this field.
Some ISPs (like Mindspring, Earthlink, and T-DSL) require that you use your full email
address when you log in. If your ISP requires your full email address, type it in this field.
Password
. Type the password that you use to log in to your ISP.
Service Name
. If your ISP provided a service name, enter it here. Otherwise, you can leave
this field blank.
Connection Mode
. This specifies when the router should establish the PPPoE connection.
Currently the connection mode is
always on
to provide a steady IPv6 connection. The router
never disconnects the connection, and in case the connection is broken (such as if the
modem is turned off), the router establishes the connection right after the PPPoE connection
is available.
The other settings are the same as Auto Detect mode. See
IPv6 LAN Setup
and

Quick Tips
This section describes tips for troubleshooting some common problems.
Sequence to Restart Your Network
Be sure to restart your network in this sequence:
1.
Turn off and unplug the modem.
2.
Turn off the router and computers.
3.
Plug in the modem and turn it on. Wait 2 minutes.
4.
Turn on the router and wait 2 minutes.
5.
Turn on the computers.
Check Ethernet Cable Connections
Make sure that the Ethernet cables are securely plugged in:
The Internet LED on the router is on if the Ethernet cable connecting the router and the
modem is plugged in securely and the modem and router are turned on.
For each powered-on computer connected to the router by an Ethernet cable, the
corresponding numbered router LAN port LED is on.
Hard Disk Drive (HDD)
If you turn off the router when an HDD is installed, wait 2 seconds before turning it back on to
give the HDD enough time to reset.
If the HDD LED is red and it used to be green, the HDD connection could be loose. Turn off
the router. Disconnect the HDD, and then connect it again. Turn on the router and check the
HDD LED.
Wireless Settings
Make sure that the wireless settings in the computer and router match exactly.
For a wirelessly connected computer, the wireless network name (SSID) and wireless
security settings of the router and wireless computer need to match exactly.
If you set up an access list in the Advanced Wireless Settings screen, you have to add
each wireless computer’s MAC address to the router’s access list.

Network Settings
Make sure that the network settings of the computer are correct:
Wired and wirelessly connected computers need to have network (IP) addresses on the
same network as the router. The simplest way to do this is to configure each computer to
obtain an IP address automatically using DHCP.
Some cable modem service providers require you to use the MAC address of the
computer initially registered on the account. You can view the MAC address in the
Attached Devices screen.
Troubleshooting with the LEDs
After you turn on power to the router, the following sequence of events should occur:
1.
When power is first applied, verify that the Power LED
is on.
2.
Verify that the Power LED turns amber within a few seconds, indicating that the self-test is
running.
3.
After 2 minutes, verify the following:
The Power LED lights solid green.
The Internet LED lights.
The Wireless LED lights blue.
The LEDs on the front panel of the router can be used for troubleshooting.
Power LED Is Off or Blinking
Make sure that the power cord is securely connected to your router and that the power
adapter is securely connected to a functioning power outlet.
Check that you are using the 12V DC, 5A power adapter that NETGEAR supplied for this
product.
If the Power LED blinks slowly and continuously, the router firmware is corrupted. This can
happen if a firmware upgrade is interrupted, or if the router detects a problem with the
firmware. If the error persists, you have a hardware problem. For recovery instructions, or
help with a hardware problem, contact technical support at
www.netgear.com/support.
Power LED Stays Amber
When the router is turned on, the Power LED turns amber for about 20 seconds and then
turns green. If the LED does not turn green, the router has a problem.
If the Power LED is still amber 1 minute after you turn on power to the router:
1.
Turn off the power and then turn it back on to see if the router recovers.
2.
Press and hold the
Reset
button to return the router to its factory settings. as explained
in
Restore the Factory Settings and Password
