Configuring Wireless on the SOHO TZW Page 25
Considerations for Using Wireless Connections
• Mobility - if the majority of your network is laptop computers, wireless is more portable than
wired connections.
• Convenience - wireless networks do not require cabling of individual computers or opening
computer cases to install network cards.
• Speed - if network speed is important to you, you may want to consider using Ethernet
connections rather than wireless connections.
• Range and Coverage - if your network environment contains numerous physical barriers
or interference factors, wireless networking may not be suitable for your network.
• Security - wireless networks have inherent security issues due to the unrestrictive nature
of the wireless transmissions. However, the SOHO TZW is a firewall and has NAT
capabilities which provides security, and you can use WEP to secure data transmissions.
Recommendations for Optimal Wireless Performance
• Place the SOHO TZW near the center of your intended network. This can also reduce the
possibility of eavesdropping by neighboring wireless networks.
• Minimize the number of walls or ceilings between the SOHO TZW and the receiving points
such as PCs or laptops.
• Try to place the TZW in a direct line with other wireless components. Best performance is
achieved when wireless components are in direct line of sight with each other.
• Building construction can make a difference on wireless performance. Avoid placing the
TZX near walls, fireplaces, or other large solid objects. Placing the TZW near metal objects
such as computer cases, monitors, and appliances can affect performance of the unit.
• Metal framing, UV window film, concrete or masonry walls, and metallic paint can reduce
signal strength if the TZW is installed near these types of materials.
• Installing the TZW in a high place can help avoid obstacles and improve performance for
upper stories of a building.
• Neighboring wireless networks and devices can affect signal strength, speed, and range of
the SOHO TZW. Also, devices such as cordless phones, radios, microwave ovens, and
televisions may cause interference on the TZW.
Adjusting the SOHO TZW Antennas
The antennas on the SOHO TZW can be adjusted for the best radio reception. Begin with the
antennas pointing straight up, and then adjust as necessary. Note that certain areas, such as
the area directly below the SOHO TZW, get relatively poor reception. Pointing the antenna
directly at another wireless device does not improve reception. Do not place the antennas next
to metal doors or walls as this can cause interference.
