Linksys® E2000 Wireless-N Router Configuration Guide
1 Introduction
Thank you for purchasing the Maretron preconfigured Linksys®E2000 Wireless-N Router (from
here on referred to as WiFi/Router). The WiFi/Router is used to interconnect one or more wired
or wireless devices running Maretron’s N2KView®vessel monitoring and control software with
a device running Maretron’s N2KServer® (i.e., N2KServer®runs on Maretron’s Internet
Protocol Gateway (IPG100) or a PC connected to an NMEA 2000®network via Maretron’s
USB gateway (USB100)). Figure 1 shows a typical configuration where multiple devices
running Maretron’s N2KView®software (e.g., laptop computer, desktop computer, smart
phone, tablet, Maretron DSM800 display, or Maretron MBB100 black box) are connected back
to an NMEA 2000®network through the WiFi/Router and the Maretron Internet Protocol
Gateway (IPG100).

Although the WiFi/Router is mostly pre-configured by Maretron, there are a few steps that must
be performed to establish the connection between Maretron’s N2KView®vessel monitoring
and control software (client) and Maretron’s N2KServer®(server). If you are installing a system
similar to Figure 1 where the N2KServer®is running on the IPG100, then you should read
paragraphs 2, 2.1 and 2.2 (skip paragraph 2.3). If you are installing a system where
N2KServer is running on a PC then you should read paragraphs 2, 2.1 and 2.3 (skip paragraph
2.2).

2 Configuring the WiFi/Router
The settings in the WiFi/Router are changed using a web browser such as Internet Explorer,
Safari, or Mozilla Firefox.
2.1 Connecting to the WiFi/Router
Connect the WiFi/Router to your PC using the blue Ethernet cable supplied in the box. Use the
supplied AC adapter to power the WiFi/Router.
Open your Internet browser and type 192.168.1.1 in the address field, and then press Enter. If
you connect successfully to the router, the browser will display a screen requesting a
username and password.
For Mozilla Firefox, this would look like:
and for Internet Explorer the corresponding screens would be:
Page 6 Revision 1.1

®®
From now on, we will just show the screens from Firefox – the screens from other browsers will
be very similar.
Leave the User name blank, and enter the default Password, which is admin and press the
OK button.
You may see the following message:
Cisco connect is a utility that comes with the router. It generalizes the setup procedures, but
we will not be using it to configure the WiFi/Router, so press the OK button to remove the
message.
Revision 1.1 Page 7

Linksys® E2000 Wireless-N Router Configuration Guide
You are now connected to the WiFi/Router, and should see the following basic setup screen.
Page 8 Revision 1.1

®®
Whenever you make a change to the configuration, you will see the following message:
You can press Continue whenever this message is displayed to get back to the configuration
screens.
2.2 Adding an IPG100 to the Network.
Connect Maretron’s Internet Protocol Gateway (IPG100) to the WiFi/Router using an Ethernet
Cable. The cable plugs into one of the blue Ethernet sockets at the back of the router. Reset
the IPG100 by removing the NMEA2000 cable and re-attaching it. This forces the IPG100 to
connect to this router, and removes previously allocated addresses.
Now we want to get the MAC address of the IPG100, so that we can reserve an IP Address for
it. Having a constant, reserved IP Address for the IPG100, makes it easy for N2KView®clients
to find the IPG100 on the network. We will choose to use the address 192.168.1.3 for the
IPG100. Note that if you have more than one IPG100 or PC-based N2KServer®, then each one
must have a unique reserved address, but this is beyond the scope of these instructions, so
please contact Maretron Technical Support for assistance.
Inside the WiFi/Router is a DHCP Server, which is responsible for assigning IP addresses to
other network devices that request them. DHCP stands for Dynamic Host Configuration
Protocol.
The IPG100 on the network will be identified by the Client Name of IPG100_<serial number>.
Revision 1.1 Page 9

Linksys® E2000 Wireless-N Router Configuration Guide
From the Basic Setup page, open the DHCP Reservation Table by pressing the DHCP
Reservation button.
The DHCP Reservation table is displayed as shown below:
If you do not see an IPG100 in the top part of the table, then it has not requested an address
from the DHCP Server. Ensure that DHCP is set to Yes in the device configuration of the
IPG100 (refer to the IPG100 manual).
Page 10 Revision 1.1

To make these settings take effect, reset the IPG100 by disconnecting the NMEA2000 cable,
and then re-connecting.
2.3 Adding a PC based N2KServer®to the Network.
In addition to the PC connected to the WiFi/Router used to configure the WiFi/Router, also
connect the PC slated to run the N2KServer®to the WiFi/Router using an Ethernet Cable. The
cable plugs into one of the blue Ethernet sockets at the back of the WiFI/Router.
Now we want to get the MAC address of the PC running N2KServer®, so that we can reserve
an IP Address for it. Having a constant, reserved IP Address for N2KServer®, makes it easy for
N2KView®clients to find N2KServer®on the network. We will choose to use the address
192.168.1.3 for the N2KServer®. Note that if you have more than one IPG100 or PC-based
N2KServer®, then each one must have a unique reserved address, but this is beyond the
scope of these instructions, so please contact Maretron Technical Support for assistance.
Inside the WiFi/Router is a DHCP Server, which is responsible for assigning IP addresses to
other network devices that request them. DHCP stands for Dynamic Host Configuration
Protocol.
The PC running N2KServer®on the network will be identified by name of the PC.
From the Basic Setup page, open the DHCP Reservation Table by pressing the DHCP
Reservation button.
Page 12 Revision 1.1

3 Resetting the WiFi/Router to Maretron
Configuration
In addition to the parameters that must be set by the user described in paragraph 2, several
parameters are set by Maretron at the factory. If the factory settings are ever lost, then you can
reset the WiFi/Router and program the factory setting by following the instructions outlined in
the following paragraphs.
3.1 Physically Reset the WiFi/Router
At the back of the WiFi/Router is a small red button. Hold it down until the lights at the top of
the router turn yellow (about 5 seconds). You router has now been reset to the original factory
configuration, and now needs the original Maretron configuration to be restored.
3.2 Give your Wireless Network a name
When you connect a device to a router using the wireless connection, you are generally shown
a list of wireless devices to which you can connect. The name that you give to your router will
help you identify this router. The name will be preset to N2KRouter followed by the last five
digits of the router’s serial number.
Make sure that you are looking at the Basic Wireless Settings page, by clicking on Wireless
and then Basic Wireless Settings. These will both show white lettering on a blue background
when you are on the correct page.
Change the Configuration View to Manual.
Revision 1.1 Page 17

Linksys® E2000 Wireless-N Router Configuration Guide
In the Network Name (SSID) field, replace the word Cisco with Maretron, leaving the 5 digits
from the serial number intact.
3.3 Programming network security
This section details the programming of WiFi/Router to ensure that wireless messages to and
from the router are encrypted against eavesdropping.
Make sure that you are looking at the Wireless Security page, by clicking on Wireless and
then Wireless Security.
Change the Security Mode to WPA2/WPA Mixed Mode.
The Passphrase is used to encrypt the data passed between the router and wireless devices.
It must be entered identically on all wireless devices connected to the router. Maretron will
choose a secure passphrase, and attach a copy of it to the underside of the router. Carefully
enter this phrase into the Passphrase box in the above dialog.
Every WiFi/Router will be pre-programmed with a different passphrase, so that if more than
one boat in close proximity have WiFi/Routers, their security will not be compromised.

Appendix A- Client/Server Architecture
The N2KView®Vessel Monitoring and Control System is based on a client/server architecture.
In this context, a server is defined as a component that provides services over a network and a
client is defined as a station that requests and uses those services.
Within the N2KView®System, there is generally one server (called N2KServer®) and one or
more stations or clients (called N2KView®). The server component is implemented by either an
IPG100 or N2KServer®software running on a Windows PC, and the station or client
components are implemented by the N2KView®software. N2KView®software may run on a
Windows PC, Mac, or Maretron®’s MBB100 or DSM800. Mobile versions of N2KView®
software are available for iPod Touch, iPhone, iPad and most Android devices. The service
offered by the server to the stations (clients) is access to the NMEA 2000®network data that
the server receives from the NMEA 2000®network via its NMEA 2000®gateway. The network
over which this service is offered is implemented as a TCP/IP (Transmission Control
Protocol/Internet Protocol) network, which is discussed in the next section.

Linksys® E2000 Wireless-N Router Configuration Guide
A.1 Examples of NMEA 2000® Client/Server Architectures
N2KServer®may run on a Windows PC (using Maretron’s USB100 gateway - see and ) or
N2KServer®may run directly on an IPG100 (see Figure 2).
Figure 2 – LAN Client/Server Architecture Example with USB100
Figure 2 shows an example of a Local Area Network (LAN) connection including the PC to
NMEA 2000®network connection through a USB100 gateway. A copy of N2KServer®must run
on the PC connected to the USB100, and an N2KView®Hardware License Key must be
plugged in to the PC to supply sufficient licenses for the maximum number of simultaneously
connected clients. N2KView®clients may run on either the PC connected to the USB100, or to
another PC connected to the router, or to a laptop or mobile device connected wirelessly.
