What are wireless network connections?
Your wireless network adapter uses a wireless protocol (called IEEE 802.11b/g or WiFi) to
communicate with the Streamium LCD TV by means of radio transmissions. WiFi radio
waves travel outwards from the antenna in all directions, and can transmit through walls
and floors. WiFi can theoretically reach up to 200 meters in an open environment and
reach speeds of up to 11 (b) or 54 (g) megabits per second (Mbps) at close range. However,
the actual network range and data throughput rate will always be less, depending on the
wireless signal quality.
Factors determining your network range and network speed
• Wireless signals travel farther outside of buildings, and when the wireless components
are in direct line of sight to one another. Putting wireless components high up helps
avoid physical obstacles and provides better coverage.
• Building construction such as metal framing and concrete or masonry walls and floors
will reduce radio signal strength. Avoid putting wireless components next to walls and
other large, solid objects; or next to large metal objects such as computers, monitors,
and appliances.
• Wireless signal range, speed, and strength can be affected by interference from
neighbouring wireless networks and devices. Electromagnetic devices such as televisions,
radios, microwave ovens, and cordless telephones, especially those with frequencies in
the 2.4 GHz range, may also interfere with wireless transmission.
• Standing or sitting too close to wireless equipment can also affect radio signal quality.
• Adjusting the antennas: Certain areas, such as directly below the antenna, get relatively
poor reception. Moving the antenna slightly may improve your reception. Note : Pointing
the antenna toward another wireless component will not improve reception.
Securing your wireless network
Since wireless computer networks use radio signals, it is possible for other wireless network
devices outside your immediate area to pick up the wireless signals and either connect to
your network or to capture the network traffic.Therefore, you should always enable the
Wired Equivalent Privacy (WEP) network encryption key to help prevent unauthorised
connections or the possibility of eavesdroppers listening in on your network traffic.
What is WEP?
WEP is a 64-bit or 128 bit encryption key for securing your wireless network communication.
Preferably, you should use the highest encryption strength available. Always enter the same
key with the same length for all your home network computers and for the Streamium
LCD TV.
Securing your network from Internet access
Check in the documentation of your Wireless Base Station or gateway router whether it
provides you with a built-in firewall and network address translation (NAT), providing
security for an ‘always-on’ broadband Internet connection that is being shared among the
computers and devices on your home network. Computers on an ad-hoc network may
share an Internet connection that is set up on one of the computers (ICS). However, a
firewall is usually not built-in and you should install one on the computer that is sharing the
Internet connection.
What is a firewall?
A firewall acts as a barrier that helps protect your network from outside intruders.The
firewall specifies what information can be communicated from the computers on your
network to the Internet, and from the Internet to the computers on your network.
