1. Introduction
Your 3G8WV –HSPA Wi-Fi Router with Voice
The NetComm 3G8WV integrates a Wireless LAN, HSPA module and voice gateway into one stylish unit. Insert an
active HSPA SIM card into the slot on the rear panel and get instant access to a 3G Internet connection.
The NetComm 3G8WV incorporates a WLAN 802.11b/g/n access point, two Ethernet 10/100Mbps ports and two
phone ports for voice calls. It features the latest security options such as WPA2 data encryption, SPI Firewall and

2. Placement of your 3G8WV
Just like your mobile phone, a 3G Router’s location will affect its signal strength to the 3G Mobile Base Station (Cell
Tower). The data speed achievable from a 3G Router is relative to this signal strength, which is affected by many
environmental factors. Please keep in mind that the 3G Router will need adequate signal strength in order to
provide Internet connectivity whilst choosing a location to place your 3G8WV.
Similarly to the 3G Router, 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 five meters from the Router in order to see if distance is the
problem. If difficulties 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.

3G8WV User Guide
Page 5 of 43
2.1 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 floor that is as close to the centre of the home as possible. This may
mean placing the Router on an upper floor.
• Try not to place the Router near a cordless telephone that operates at the same radio frequency as the 3G8WV
(2.4GHz).
2.2 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).
2.3 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 fixes the problem, your phone may be interfering with the Wi-Fi Router.

3G8WV User Guide
Page 6 of 43
• 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.
2.4 Choose the “Quietest” Channel for your Wireless Network
In locations where homes or offices are close together, such as apartment buildings or office complexes, there may
be wireless networks nearby that can conflict 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 find 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.
3. Product Layout
3.1 Connecting and Configuring your Router
The Router has been designed to be placed on a desktop. All of the cables exit from the rear of the Router for
better organization. The display is easily visible on the FRONT of the Router to provide you with information about

3G8WV User Guide
Page 20 of 43
Advanced Routing –Static
Static Routing allows computers that are connected to your 3G Router to communicate with computers on another
LAN segment which are connected to it via another router. To set a rule, you need to specify the following:
• Destination
• Subnet mask
• Gateway
• Interface
Advanced Routing –Dynamic
Dynamic Routing uses the RIP protocol to allow the 3G Router to adapt to changes in the network. RIP enables the
device to determine the best route for each packet based on the “hop count” or number of hops between Source
and Destination. To enable Dynamic Routing, select Enable from the drop box and click Apply.
