network must be in "Infrastructure" mode.
If your Media Center PC is connected to the wireless network, it must be
connected with an internal wireless networking PCI card or with an Ethernet
wireless adapter (bridge). USB wireless adapters are not supported.
Accessing the Network Performance Tuner
When a Media Center Extender is initially set up with your Media Center PC the Network
Bandwidth Monitor is launched in "Automatic Test" mode after setup is complete to
ensure that the current network configuration is capable of delivering a quality TV video
experience.
The Network Performance Tuner is also accessible at any time from the Windows Start
menu under "All ProgramsàAccessoriesàMedia Center".
Getting Started
In order to use the Network Performance Tuner ensure your Media Center Extender is
setup successfully and when turned on it shows the Media Center "Start" main menu. To
accurately understand the performance of your network make sure no media playback is
occurring on the Media Center Extender while the Network Performance Tuner is in use
(Live TV, Recorded TV, Music, My Videos, or Radio). For best results, turn off your
Media Center Extender then turn it back on again before use so that all Media Center
Extender resources are cleaned up.
The Network Performance Monitor
The Network Performance Monitor is an advanced utility which measures the overall
bandwidth between a Media Center PC and a Media Center Extender in the same way
as the Automatic Test. The difference is that the Network Performance Monitor runs
indefinitely continually showing the results of the testing on a graph displayed on the
screen. The purpose of this utility is that it allows you to make changes to your network
configuration, such as changing the location of your access point or modifying the
position of antennas, while you can see the results of those changes in real-time.
When using the Network Performance Monitor the objective is to make adjustments to
your network configuration until you can keep the green graph line consistently above the
solid yellow line in the middle of the screen. The higher above the yellow line you can get
your network performance the less likely you are to have problems watching TV on your
Media Center Extender. See the troubleshooting sections below for more detailed
suggestions for how to improve your network performance.
