IEEE 802.11a or 802.11g is the second choice.
IEEE 802.11b access points work well for audio
and picture streaming, but are not recommended
for video because of bandwidth limitations.
The quality of streaming video over wireless
depends on many factors such as the bitrate of the
original video, the reception quality, and the
access point.
The 802.11b and 802.11g routers operate at
radio frequencies that are also used by other
household devices, and can be affected by
interference from cordless phones, microwave
ovens, X10 wireless video cameras, ham radios,
or Bluetooth devices such as a cellular phone
headset. The 802.11n or 802.11a routers
operate at frequencies that other wireless devices
are less likely to use.
Walls dramatically reduce the range of a wireless
router. It is recommended that your router be
placed in a room in the middle of your house. For

the purpose of video transmission, avoid wireless
connections that go through more than two walls
or two floors. An 802.11n router performs better
in these environments due to their use of
advanced signal processing and multiple
antennas.
Turn off all unused network equipment in your
local home network. Some devices generate
network traffic even when they are idle.
Most wireless routers offer multiple communication
channels. Refer to your router user manual for
more information. In apartment buildings and
dense neighborhoods, if reception is poor, you
may need to switch your router wireless channel to
improve reception. The 802.11n* and 802.11a
routers offer more channels, and so are less prone
to WI-FI interference. In some instances, rotating
your router antennae may improve your reception.
*Your 802.11n router may have a single transmitter at 2.4 GHz or a
dual transmitter at both 2.4 GHz and 5 GHz. If it is available, select
the 5 GHz mode for better coverage and performance.
