Wi-Fi Protected Setup Method

Wi-Fi Protected Setup (WPS) is a standard for easily adding computers and other devices to a home netw ork while maintaining security .T o use WPS (Push 'N' Connect), make sure that all WiFi de vices to be connected to the network are Wi-Fi certified and support WPS. During the connection process, the client gets the security settings from the modem router so that every device in the network supports the same security settings.

To use WPS to connect a device to the WiFi network of the modem router:

1. Make sure that the modem router is receiving power (its Power LED is lit).

2. Check the WPS instructions for your computer or WiFi device.

3. Press the WPS button of the modem router for three seconds.

4. Within two minutes, press the WPS button on your WiFi device, or follow the WPS instructions that came with

the device. The WPS process automatically sets up the device with the network password and connects the device to the

WiFi network of the modem router. For more information, see Use WPS to Add a Device to the WiFi Network on page 108.

Types of Logins

Separate types of logins serve different purposes.This section describes the differences so that you know which login to use when.

Types of logins:

Install and Access the Modem Router and Its Network

Nighthawk X4S AC2600 WiFi VDSL/ADSL Modem Router Model D7800

• ISP login.The login that your Internet service provider (ISP) gave y ou logs you in to your Internet service.Your

ISP gave you this login inf ormation in a letter or some other wa y. If you cannot find this login inf ormation, contact your ISP.

• WiFi network key or password.Your modem router is preset with a unique WiFi network name (SSID) and

password f or WiFi access.This information is on the product label. Use this inf ormation to connect a WiFi device to the WiFi network of the modem router.

• Modem router login.This logs you in to the modem router’s web pages from a web browser as admin.

Automatic Internet Setup

You can use NETGEAR genie to set up the modem router automatically, or you can use the modem router’s web pages to set up the modem router manually.

Automatic Internet setup with NETGEAR genie functions with both types of Internet service that the modem router supports:

• DSL service. If you install your modem router for DSL service (the modem router supports ADSL and VDSL

service), you can set up your modem router with NETGEAR genie, which launches the first time that you set up the Internet connection for your modem router.NETGEAR genie runs on any device with a web browser.

For more information, see Set Up Your Modem Router for DSL Service on page 24.

• Cable or fiber service. If you install your modem router for cable or fiber service, you can set up your modem

router with NETGEAR genie, which launches the first time that you set up the Internet connection for your modem router. NETGEAR genie runs on any device with a web browser.

For more information, see Set Up the Modem Router for Cable or Fiber Service on page 32.

After initial installation and setup, the NETGEAR Setup Wizard is alwa ys accessible to assist

Note

you with setting up an installation with DSL service or an installation with cable or fiber service. For more information, see Use the Internet Setup Wizard After Initial Setup on page 45.

Whether you install your modem router f or DSL service or for cable or fiber service, y ou can always use the modem router’s web pages to set up the modem router manually.

Before you start the setup process, get your ISP inf ormation and make sure that the settings that are described here are specified for the computers and devices in the network.

When your Internet service starts, your Internet service provider (ISP) typically gives you all the inf ormation that you need to connect to the Internet. For DSL service, you might need the following information to set up your modem router:

• The ISP configuration information for your DSL account

• ISP login name and password

• Fixed or static IP address settings (special deployment by ISP; this setting is rare)

Install and Access the Modem Router and Its Network

Set Up Your Modem Router for DSL Service

You can install your modem router for DSL service or for cable or fiber (Ethernet WAN) service. If you use a DSL modem, follow the procedure that is described in Cable the Modem Router f or DSL Service and Access the Modem

Router on page 24. If you use a cable or fiber modem, follow the procedure that is described in Set Up the Modem Router for Cable or Fiber Service on page 32.

DSL Service

Make sure that your ADSL or VDSL service is active before you install the modem router.You need the following information to install your DSL modem and connect to the Internet:

• DSL user name and password.This information is included in the welcome letter your DSL ISP sent you when

you signed up for your service. Record your DSL Internet service account user name and password.

• Your telephone number or DSL account number. If you do not use voice service, you can use your DSL

account number in place of a phone number.

If you do not know or cannot locate your DSL user name and password, call your DSL Internet service provider (ISP). Be specific when speaking with your DSL Internet service provider. For example, you could say, “I need my DSL service user name and password. Can you help me?”

If your provider says that they do not support NETGEAR services, tell them that you need

Note

only your DSL user name and password.You do not need support.

Specify an IPv6 Internet Connection

If you want to use an IPv6 Internet connection, you must specify the settings manually. NETGEAR genie and the Setup Wizard do not detect an IPv6 Internet connection automatically.

IPv6 Internet Connections and IPv6 Addresses

The modem router can support an IPv6 Internet connection through the following connection types:

• Auto Detect. For more information, see Set Up an IPv6 Connection Through Auto Detect on page 81.

• 6to4 tunnel. For more information, see Set Up an IPv6 6to4 Tunnel Connection on page 83.

Manage the Internet Settings Manually

Nighthawk X4S AC2600 WiFi VDSL/ADSL Modem Router Model D7800

• Pass-through. For more information, see Set Up an IPv6 Pass-Through Connection on page 85.

• Fixed. For more information, see Set Up an IPv6 Fixed Connection on page 85.

• DHCP. For more information, see Set Up an IPv6 DHCP Connection on page 87.

• PPP over Ethernet. For more information, see Set Up an IPv6 PPPoE Connection on page 89.

• Auto Config. For more information, see Set Up an IPv6 Connection Through Auto Config on page 91.

Which connection type you must use depends on your IPv6 ISP. Follow the directions that your IPv6 ISP gave you.

• If your ISP did not provide details, use the 6to4 tunnel connection type (see Set Up an IPv6 6to4 Tunnel Connection on page 83).

• If you are not sure what type of IPv6 connection the modem router uses, use the Auto Detect connection type,

which lets the modem router detect the IPv6 type that is in use (see Set Up an IPv6 Connection Through Auto

Detect on page 81).

• If your Internet connection does not use PPPoE, DHCP, a fixed IP address, or pass-through but is IPv6, use

the Auto Config connection type, which lets the modem router autoconfigure its IPv6 connection (see Set Up

an IPv6 Connection Through Auto Config on page 91).

When you enable IPv6 and select any connection type other than IPv6 pass-through, the modem router starts the stateful packet inspection (SPI) firew all function on the W AN interface.The modem router creates connection records and checks every inbound IPv6 packet. If the inbound packet is not destined to the modem router itself and the modem router does not expect to receive such a packet, or the packet is not in the connection record, the modem router blocks this pack et.This function works in two modes: In secured mode, the modem router inspects both TCP and UDP packets. In open mode, the modem router inspects UDP packets only.

IPv6 addresses are denoted by eight groups of hexadecimal quartets that are separated by colons.You can reduce any four-digit group of zeros within an IPv6 address to a single zero or omit it.The following errors invalidate an IPv6 address:

• More than eight groups of hexadecimal quartets

• More than four hexadecimal characters in a quartet

• More than two colons in a row

Set Up an IPv6 Connection Through Auto Detect

If you are not sure what type of IPv6 connection the modem router uses, use the Auto Detect connection type , which lets the modem router detect the IPv6 type that is in use.

Manage the MTU Size

The maximum transmission unit (MTU) is the largest data packet a network device transmits.

MTU Concepts

When one network device communicates across the Internet with another, the data packets travel through many devices along the way. If a device in the data path uses a lower maximum transmission unit (MTU) setting than the other devices, the data packets must be split or “fragmented” to accommodate the device with the smallest MTU.

The best MTU setting for NETGEAR equipment is often the default value. In some situations, changing the value fixes one problem but causes another.

Leave the MTU unchanged unless one of these situations occurs:

• You experience problems connecting to your ISP or other Internet service, and the technical support of either

the ISP or NETGEAR recommends changing the MTU setting.These web-based applications might require an MTU change:

• A secure website that does not open or displays only part of a web page

• Yahoo email

• MSN portal

• America Online’s DSL service

• You use VPN and experience severe performance problems.

• You used a program to optimize MTU for performance reasons and now you are experiencing connectivity or

performance problems.

If you suspect an MTU problem, a common solution is to change the MTU to 1400. If you are willing to experiment, you can gradually reduce the MTU from the maximum value of 1500 until the problem goes away. The following table describes common MTU sizes and applications.

WARNING:

An incorrect MTU setting can cause Internet communication problems. For example, you might not be able to access certain websites, frames within websites, secure login pages, or FTP or POP servers. Change the MTU only if you are sure that it is necessary for your ISP connection.

To change the MTU size:

1. Launch a web browser from a computer or WiFi device that is connected to the network.

2. Enter http://www.routerlogin.net.

A login window opens.

3. Enter the modem router user name and password.

The user name is admin.The default password is password.The user name and password are case-sensitive . The BASIC Home page displays.

4. Select ADVANCED > Setup > WAN Setup.

The WAN Setup page displays.

Manage the Basic WiFi Settings and WiFi Security of the Main Network

The modem router comes with preset security.This means that the WiFi network name (SSID), network key (password), and security option (encryption protocol) are preset in the factory. The preset SSID and password are uniquely generated for every device to protect and maximize your WiFi security.You can find the preset SSID and password on the product label (see Bottom Panel Product Label on page 17).

IMPORTANT:

We recommend that you do not change your preset security settings. If you do decide to change your preset security settings, make a note of the new settings and store the note in a safe place where you can easily find it.

View or Change the Basic WiFi Settings

You can view or change the basic WiFi settings and WiFi security. The modem router simultaneously supports the

2.4 GHz band for 802.11b/g/n devices and the 5 GHz band for 802.11a/n/ac devices.

If you do decide to change the WiFi settings of the modem router’s main network, use a wired

the SSID, enter a 32-character (maximum), case-sensitive name in this field.

From the Channel menu, select Auto for automatic channel selection or select an individual channel.The default selection is Auto.

In some regions, not all channels are available. Do not change the channel

Note

unless you experience interference (shown by lost connections or slow data transfers). If this situation occurs, experiment with different channels to see which is the best.

If you use multiple WiFi access points (APs), reduce interference by selecting

Note

different channels for adjacent APs.We recommend a channel spacing of four channels between adjacent APs (for example , use Channels 1 and 5, or 6 and

10).
