NetComm Liberty Series - 3G Wireless N300 Router
Introduction
Your 3G18Wn - 3G Wireless N300 Router
Congratulations on your purchase of a NetComm 3G18Wn - 3G Wireless N300 Router. This product is a high-performance router that
provides wireless networking and Internet connectivity for your home, ofce or public space. The NetComm 3G18Wn supports an
external 3G USB Modem which enables you to share a 3G Mobile Broadband service among multiple computers.
This product also features a WAN Ethernet port to connect the 3G18Wn to a xed line (xDSL/Cable/Satellite) service to provide alternate
Internet connectivity. The 3G18Wn also allows for a 3G Mobile Broadband connection provided by a 3G USB modem to act as a backup
Internet connection to an existing xed line service, providing automatic Internet failover to 3G in the event that the ADSL/Cable/Satellite
service fails. The product features four 10/100 LAN ports for wired computers, and also features a built in Wireless Access Point which
enables you to connect computers and laptops wirelessly to the Internet via the router.
The 3G18Wn features the latest standards of wireless security, with wireless security enabled by default on each router. An advanced
rewall and VPN pass-through functionality allows for maximum security and caters for the encrypted Point-to-Point communications from
connected computers through the 3G18Wn to a VPN Server.
The Port Forwarding and UPnP functionality provided by the 3G18Wn make it easier for today’s Internet users to setup and congure the
various Network Port Rules needed by Internet applications such as On-Line Gaming, Peer-To-Peer le sharing and Instant Messaging services.

NetComm Liberty Series - 3G Wireless N300 Router
Placement of your 3G18Wn
Just like your mobile phone, a 3G USB Modem’s location will affect its signal strength to the 3G Mobile Base Station (Cell Tower). The data
speed achievable from a 3G USB modem is relative to this signal strength, which is affected by many environmental factors. Please keep
in mind that the 3G USB Modem will need adequate signal strength in order to provide Internet connectivity whilst choosing a location to
place your 3G18Wn - 3G Wireless N300 Router.
Similarly to the 3G USB Modem, the wireless connection between the Router and your Wi-Fi devices will be stronger the closer your
connected devices are to your Router. Your wireless connection and performance will degrade as the distance between your Router and
connected devices increases. This may or may not be directly noticeable, and is greatly affected by the individual installation environment.
If you have concerns about your network’s performance that might be related to range or obstruction factors, try moving the computer to
a position between three to ve meters from the Router in order to see if distance is the problem. If difculties persist even at close range,
please contact NetComm Technical Support.
Note: While some of the items listed below can affect network performance, they will not prohibit your wireless network from functioning; if you are concerned that your network is
not operating at its maximum effectiveness, this checklist may help.
Router Placement
Place your Router as close as possible to the centre of your wireless network devices. To achieve the best wireless network coverage for
your “wireless clients” (i.e., computers with built in or USB wireless adapters, laptops with built-in wireless, Wireless PDA / iPhone, etc):
• Ensure that your Router’s antennas are parallel to each other, and are positioned vertically (toward the ceiling). If your Router itself
is positioned vertically, point the antennas in an upward direction as much as possible.
•In multi-storey homes, place the Router on a oor that is as close to the centre of the home as possible. This may mean placing the
Router on an upper oor.
•Try not to place the Router near a cordless telephone that operates at the same radio frequency as the 3G18Wn (2.4GHz).
Avoid obstacles and interference
Avoid placing your Router near devices that may emit radio “noise,” such as microwave ovens. Dense objects that can inhibit wireless
communication include:
• Refrigerators
• Washers and/or dryers
• Metal cabinets
• Large aquariums
• Metallic-based, UV-tinted windows
If your wireless signal seems weak in some spots, make sure that objects such as these are not blocking the signal’s path (between your
devices and Router).

Cordless Phones
If the performance of your wireless network is impaired after considering the above issues, and you have a cordless phone:
•Try moving cordless phones away from your Router and your wireless-enabled computers.
•Unplug and remove the battery from any cordless phone that operates on the 2.4GHz band (check manufacturer’s information). If
this xes the problem, your phone may be interfering with the Wi-Fi Router.
•If your phone supports channel selection, change the channel on the phone to the farthest channel from your wireless network.
For example, change the phone to channel 1 and move your Router to channel 11. See your phones user manual for detailed
instructions.
•If necessary, consider switching to a 900MHz or 5GHz cordless phone.
Choose the “Quietest” Channel for your Wireless Network
In locations where homes or ofces are close together, such as apartment buildings or ofce complexes, there may be wireless networks
nearby that can conict with your wireless network.
Use the Site Survey capabilities found in the Wireless Utility of your wireless adapter to locate any other wireless networks that are available
(see your wireless adapter’s user manual), and switch your Router and computers to a channel as far away from other networks as
possible.
•Experiment with more than one of the available channels, in order to nd the clearest connection and avoid interference from
neighbouring cordless phones or other wireless devices.
•For NetComm wireless networking products, use the detailed Site Survey and wireless channel information included with your
wireless network card. See your network card’s user guide for more information.
These guidelines should allow you to cover the maximum possible area with your Router. Should you need to cover an even wider area, you
should consider looking at building a hybrid network by combining your wireless network with a HomePlug Network. See the NetComm
website for more details on HomePlug products.

Modem Requirements
In order to use the WAN Ethernet port for Internet Connectivity your xed line service (Cable/xDSL/Satellite) modem must be equipped with
a RJ45 Ethernet port. Many modems have both a RJ45 Ethernet port and a USB connection. If you have a modem with both Ethernet and
USB, and are using the USB connection at this time, you will be instructed to use the RJ45 Ethernet port during the installation procedure.
If your modem has only a USB port, you can request a different type of modem from your ISP, or you can purchase a modem that has an
RJ45 Ethernet port on it.
Connecting your 3G Router
Step 1 – Connect the USB 3G Modem.
Plug the USB 3G modem into the USB port.
3G USB Modem
Note: The 3G18Wn - 3G Wireless N300 Router is designed to work with 3G USB Dongles that can be used as data modems (support tethered data). Please refer to your service
provider for detailed feature information. Please refer to the NetComm website for a list of compatible 3G USB Modems
Step 2 – Connect a computer
Connect one end of the Ethernet cable into a LAN Port on the back panel of the 3G18Wn - 3G Wireless N300 Router, and the other end
into an available Ethernet port on the network adapter in the computer you will use to congure the unit.
Step 3 – Plug in the power
Connect the power adapter to the port on the back panel of your 3G Router. Then plug the other end of the power adapter into a wall
outlet or power strip.
