The Nighthawk XS4 is an improved version of its predecessor X4. It does not have tri-band technology. Instead, it has implemented the MU-MIMO technology. We tested the device on two PCs with wireless adapters.

We measured the speed of the router at different locations inside a large home. For 802.11ac standard, on the 40 MHz channel, we used the 5 GHz radio band. At 5 feet, the average speed of the device was 515 Mbps. At 15 feet, the speed we measured was 477 Mbps. Also, at 100 feet, we measured an average speed of 225 Mbps.

Next, we tested the router on the 2.4 GHz radio band on the 20 MHz channel. At 5 feet, the speed we measured was 150 Mbps on average. The peak speed, however, was 157 Mbps. At 15 feet, the speed went down to 138 Mbps. Also, at 100 feet, it was 108 Mbps.

Besides, the Netgear X4S is a 4 x4 router and that’s why we tested it on the 5 GHz radio frequency band. This time, at 5 feet, we measure the speed of 944 Mbps and at 100 feet, the speed dramatically went down to 331 Mbps.

The X4S enables the user to connect 3 external storage devices simultaneously. We tested the read and write performance of the router. We took a 3 GB folder that contains different files, we measured the speed of 43.7 Mbps for writing the folder. Likewise, the speed for reading was 78.1 Mbps. Overall, this is good storage performance.


The X4S has the same case as its predecessor. It looks like a Lockheed F-117 stealth plane. The design is stylish and attractive. It has a black matte finish and does not retain fingerprints. It has 4 upgradable antennas, which feel solid and sturdy. The X4S has a large footprint and measures 11.2 x 7.2 x 1.9 inches. The weight of the router is 1.85 pounds.

Towards the front edge on top of the router, you will see an array of LED lights. The LEDs are similar as they were on the nighthawk X4. They show the power status, internet, the 5 GHz and the 2.4 GHz Wi-Fi, first and second USB 3.0 ports, eSATA port, 4 LAN Ethernet ports, and the last two LED lights are for the button to turn the WI-FI ON or OFF and to start the WPS pairing.

On the backside of the Nighthawk X4S, you will see the ON-OFF switch, a Reset Button, 4 Ethernet 10/100/1000 Gigabit LAN ports, and 1 Ethernet 10/100/1000 Gigabit Internet port. There is also a power connector as well as the Power ON-OFF button.

Inside the recessed zone on the left side of the router’s case, you will see 2 USB 3.0 ports. On the right side, you will find an eSATA port, which is only found on the WRT1900ACS router by Linksys.

While checking the design of the router, we saw these ports on the right side. As always, we wanted the Company to put these ports on the r
