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 radios 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 eSATA port. Sharing content across your network is easy, whether

The modem router is compatible with most major DSL Internet service providers and also supports cable or fiber Internet
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.
