About The Wi-Fi Router
The SBR-AC1900P is more than just a Wi-Fi Router. This advanced Access Point is the start of a
new home network experience that offers the following benefits:
Two concurrent 802.11ac radios: one for the 5 GHz band and one for the 2.4 GHz band.
These radios provide automatic client-directed connections for optimal Wi-Fi connectivity
and speed based on a client's capability. Each radio includes a 3x3 MIMO antenna array
for the best reach, range, and throughput.
Four gigabit Ethernet ports for ultra fast wired connectivity.
A USB 3.0 port and a USB 2.0 port, for data and media storage or transfer and print
sharing.
Embedded RipCurrent technology via your home power lines, ready to connect to
RipCurrent or other compatible G.hn extenders to reliably take your network to the
farthest reaches of your environment.
The SBR-AC1900P includes the following features:
Supports Ethernet and 802.11a/b/g/n/ac wireless connections; both wired and wireless
connections can be used simultaneously.
Auto connection to RipCurrent network extenders, including the wireless settings.
Option for automated product firmware upgrades.
Network supports up to 15 connected power line extenders.
Easy to navigate User Interface, including a network set-up Wizard.
Default settings configured for standard environments, with advanced settings for
sophisticated users.
USB ports include a file structure that provides high-speed throughput and data integrity
protection.
Support for NAS and DLNA.
What is RipCurrent?
SURFboard RipCurrent is a technology that allows you to set up a high-speed home network
that uses existing AC wiring and outlets. There's no need to run additional cables; your
devices can communicate at data rates up to 1 Gbps using the network of power lines that
already exists in your home.
The SBR-AC1900P uses the power cable connected to the Wi-Fi Router to connect to the
power lines that already exist in your home. RipCurrent is based on G.hn Power Line
Communication (PLC), which is an ITU Specification managed by the HomeGrid™ Forum. This
technology allows the SBR-AC1900P to distribute all data to each of the AC power outlets in
the home. With a corresponding G.hn Extender, the Wi-Fi or wired network can be extended
to any room, including basements, garages, or far reaching bedrooms. Connect entertainment
devices, security cameras, gaming consoles, managed appliance, anything that uses IP
(Internet Protocol).
The G.hn technology is more robust than previous home power line communication
implementations to give you better ‘real world’ throughput and stability. G.hn proves much

more efficient in an environment with multiple power line networks (such as apartment
buildings or office buildings) with the capability of recognizing up to 250 other networks to
avoid interference. G.hn communications are encrypted using the advanced standard AES
128-bit encryption for secure transmissions.
In order to ensure the best performance of your G.hn network, we recommend that you only
use 3-prong grounded outlets. A 2-prong outlet will operate sufficiently, but with a lower
throughput speed.

Standby Mode
The diamond-shaped button on top of the Wi-Fi Router is used to put the Wi-Fi Router into
Standby mode. When you press this button, the Wi-Fi capability is disabled for additional
security and power savings. The front LED turns amber when Standby is activated.
Press the button again to re-activate the Wi-Fi Router.
Selecting an Installation Location
There are a number of factors to consider when choosing a location to install the Wi-Fi Router:
Is an AC outlet available nearby? For best results, the outlet should not be switched and
should be close enough to the Wi-Fi Router that extension cords are not required.
Is the modem nearby? Can you easily run cables between the Wi-Fi Router’s location and
the modem?
If you are connecting devices to the Ethernet ports, can you easily run cables between the
Wi-Fi Router’s location and those devices?
If you want to install the Wi-Fi Router on a desktop, is there enough space on either side
to keep the vents clear? Blocking the vents may cause overheating.
How close are the wireless devices? In general, the Wi-Fi Router should be located close to
the center of the user sphere. The Wi-Fi Router wireless connection range is typically 100–
200 feet (30m–65m) for 2.4 GHz signals and less for 5 GHz signals. A number of factors can
affect connection range, as described below.
Desktop Mounting Instructions
Position the Wi-Fi Router so that:
Air flows freely around it.
The back faces the nearest wall.
It will not fall to the floor if bumped or moved.
The sides of the unit are not blocked.
If the modem is not located in an ideal location for the Wi-Fi Router, you can add a RipCurrent
Network Extender to the modem device, then connect the SBR-AC1900P to the Internet using
the power line in another location.
Note: Clean the Wi-Fi Router using only a clean, slightly moistened, cloth. Do not use aerosols
in the vicinity of the Wi-Fi Router.

Factors Affecting Wireless Range
A number of factors can affect the usable range for wireless connections.
Increase range Locating the unit centrally.
Creating as much "line-of-sight" as possible with client devices.
Decrease range Metal or concrete walls between the Wi-Fi Router and other devices.
Large metal appliances, aquariums, or metal cabinets between the Wi-Fi
Router and other devices.
Interference and RF noise (2.4 GHz wireless phones, microwave ovens,
wireless speaker/receiver systems, or other wireless networks).
Placing the device in a cabinet or other enclosed space.
Note: Decreasing the range of the wireless network may be beneficial, as long as the
decreased range is sufficient for your needs. By limiting the network’s range, you reduce
interference with other networks and make it harder for unwanted users to find and connect
to the network.
Note: Setting the transmit power level to High increases the range. Setting it to Medium or
Low decreases the range proportionately. Medium or Low may be more appropriate for
high-density residential locations.
Note: For locations within the home that do not receive a steady/stable Wi-Fi signal, simply
add a RipCurrent Wi-Fi extender for full coverage in that location.
Ethernet, Wireless, or Gigabit Home Networking?
There are three ways to connect the computer (or other equipment) to the Wi-Fi Router. The
following will help you decide which is best for you:
Ethernet
Ethernet is a standard method of connecting two or more computers into a Local Area
Network (LAN). You can use the Ethernet connection if the computer has built-in Ethernet
hardware. The SBR-AC1900P provides support for up to four such connected devices.
Note: To connect more than four computers to the SBR-AC1900P through the Ethernet ports,
you need an Ethernet switch (available at computer retailers).
