Wireless performance improvements using Vista Power Options

Windows Vista introduces advanced power management features that can dramatically affect a computer's wireless performance. By default, users can choose between three power plans: Power Saver, High Performance and Balanced. Power Saver is a great profile to use when you are running on battery but will deteriorate wireless reception by minimizing the power usage of the wireless card, resulting in reduced functionality. If you suspect your computer is running on Power Saver mode, you may check and switch to other modes by manually clicking on the battery icon in the bottom left corner of your task bar and ticking one of the other profiles (High Performance when plugged in and Balanced when on Battery).

Some laptop manufactures such as Sony and HP will often include custom power plans that may set wireless cards equivalent energy efficient but lower performance modes. For optimal wireless performance on the UTORcwn network, such settings must be changed to "maximum performance" using the steps below:

  1. Click on the Vista button at the bottom corner of the screen.
  2. Type Power Options in the field provided and click Power Options from the list of programs above it.
  3. Click Change Plan Settings under the Power Saver profile (or whichever custom profile your laptop has selected).
  4. Click on Change Advanced Power Settings.
  5. Click on the + sign next to Wireless Adapter Settings for advanced options.
  6. Click on the + sign next to Power Saving mode.
  7. Click on the drop down menu next to Setting: and select Maximum Performance.
  8. Click OK and close the Power Options window.
These changes may produce noticeable improvements in wireless performance. However, not all users will see benefits. Depending on the brand and installation of the wireless card, some computers may notice 40% improvement in wireless reception (going from 3 bars to 5) while other computers will be unaffected. If connectivity issues persist, please bring your laptop to the Help Desk. Tags: UTORcwn
