Hardware Overview of the Modem Router
The NETGEAR®Nighthawk®X4S AC2600 WiFi VDSL/ADSL Modem Router Model D7800, in this manual referred to
as the modem router, delivers combined WiFi connection speeds of up to approximately AC2600 WiFi (800 Mbps1 on
2.4 GHz2 802.11n and 1733 Mbps3 on 5 GHz 802.11ac). Both the 2.4 GHz and 5 GHz r adios can be active simultaneously.
The Nighthawk X4S is ideal for homes with a high volume of network and Internet traffic from gaming and streaming. It
supports the following advanced features:
• Multi-user MIMO (MU-MIMO) for faster speeds with simultaneously streamed data for up to three devices.
• Quad Stream WiFi for up to four data streams per WiFi band to maximize connection speed.
• Dynamic QoS for performance optimization based on applications and devices, with automatic cloud updates to
optimize the most popular applications and services.
The Nighthawk X4S also provides fast central storage, backup, and streaming to every device in your home with two
USB 3.0 ports (10 times faster than USB 2.0) and an eSAT A port. Sharing content across your network is easy, whether
you are accessing stored photos and music or printing over WiFi. Stream your stored media files on any de vice anywhere
on the network. Share your music with AirPlay-compatible devices from a USB hard drive connected to the modem
router. Use the free NETGEAR ReadySHARE Vault app to back up your Windows computers to a USB hard drive
connected to the Nighthawk X4S.
1
The modem router is compatible with most major DSL Internet service providers and also supports cable or fiber Internet
service.
1. Maximum WiFi signal rate derived from IEEE standard 802.11 specifications. Actual data throughput and WiFi coverage will vary. Network conditions and
environmental factors, including volume of network traffic, building materials and construction, and network overhead, lower actual data throughput rate and
WiFi coverage. NETGEAR makes no express or implied representations or warranties about this product’s compatibility with any future standards. 802.11ac
1733 Mbps is approximately 4x faster than 802.11n 450 Mbps.
2.The 2.4 GHz performance mode requires 256 QAM support on the WiFi client.
3. Up to 1733 Mbps WiFi speeds can be achieved when you are connecting to other 802.11ac 1733 Mbps devices.

Nighthawk X4S AC2600 WiFi VDSL/ADSL Modem Router Model D7800
Position Your Modem Router
The modem router lets you access your network anywhere within the operating r ange of your WiFi netw ork. How ever ,
the operating distance or range of your WiFi connection can v ary significantly depending on the physical placement
of your modem router . For example, the thickness and n umber of walls the WiFi signal passes through can limit the
range.
Additionally , other WiFi access points in and around your home might aff ect your modem router’ s signal.WiFi access
points are routers, repeaters, WiFi range extenders , and any other device that emits a WiFi signal f or network access.
Position your modem router according to the following guidelines:
• Place your modem router near the center of the area where your computers and other devices operate and
within line of sight to your WiFi devices.
• Make sure that the modem router is within reach of an AC power outlet and near Ethernet cables for wired
computers.
• Place the modem router in an elevated location, minimizing the number w alls and ceilings betw een the modem
router and your other devices.
• Place the modem router away from electrical devices such as these:
• Ceiling fans
• Home security systems
• Microwaves
• Computers
• Base of a cordless phone
• 2.4 GHz cordless phone
• Place the modem router away from large metal surfaces, large glass surfaces, insulated walls, and items such
as these:
• Solid metal door
• Aluminum studs
• Fish tanks
• Mirrors
• Brick
• Concrete
If you are using adjacent access points, use different radio frequency channels to reduce interference.
Install and Access the Modem Router and Its Network

Nighthawk X4S AC2600 WiFi VDSL/ADSL Modem Router Model D7800
Connect to the Modem Router
During and after installation, you can connect to the modem router’s network through a wired or WiFi connection. If
you set up your computer to use a static IP address, change the settings of your computer so that it uses Dynamic
Host Configuration Protocol (DHCP).
Connect to the Modem Router Through an Ethernet Cable
You can connect your computer to the modem router using an Ethernet cable and join the modem router’s local
area network (LAN).
To connect your computer to the modem router with an Ethernet cable:
1. Make sure that the modem router is receiving power (its Power LED is lit).

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:

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)
