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:

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.

You are now connected to the WiFi/Router, and should see the following basic setup screen.

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>.

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).
