HP MediaSmart CPTOH-0707, PY043AA#ABA Feature, 802.11n, 802.11g, 802.11a, 802.11b

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.
