Troubleshooting USB wireless adaptor turns off or suddenly stops working

Description: This article will provide steps in troubleshooting the problem of a USB wireless adaptor that powers off and stops working.

Problem: Your newly installed USB wireless adaptor powers off or stops working. It is unable to connect to the internet and removing and plugging the USB adaptor seems to work for a while. Removing and reinstalling the software does not resolve the problem, even though the lights on the adaptor are on.

Resolution: The problem for the USB wireless adaptor is that Windows has control of the power management for that device and USB ports themselves. Disabling this feature in device manager should resolve this problem.

To open device manager for Windows Vista or Windows 7:
  1. Click on Start, and on the search bar type in "Device Manager". Then press Enter.

    Device Manager

  2. In device manager click on the + or triangle for network adaptors.
  3. Right click on the wireless adaptor (name will vary), and select properties.

  4. In the properties window for the wireless card, click on Power Management tab.
  5. Remove the checkmark for "Allow the computer to turn off this device to save power."
  6. Click on Ok, and restart the computer.

    Power Management

    Click OK

  7. The wireless USB adaptor will no longer power down or have trouble staying connected to the network.

Resolving an out of range error on monitor

Description: This article will provide steps in troubleshooting an out of range error when booting into windows.

Problem: Your display stops working and only shows a message of "Out of range." This happens when the computer is first turned on, coming out of hibernate, out of sleep mode, or attaching a new monitor to the computer.

Resolution: This problem is a result of the video resolution for the video card not being set correctly or has been altered unexpectedly by an update or a program shutting down incorrectly.

To overcome this problem, removing the video card driver in device manager and allowing the computer to reinstall the correct video driver will be used in this example.

  • Turn on the computer
  • Start-tapping F8 continuously until there is a windows menu
  • Using the up and down arrow keys on the keyboard, highlight Safe mode and press Enter
  • The computer will start to load, log into windows under your name or under Owner
  • For Windows Vista or Windows 7, click on Start, type Device manager on the search line

    Device Manager


  • Click on the + for display adaptors, then right-click on the video card listed below it (name may be different). Click on Uninstall.

    Display Adapters

    Uninstall


  • Leave the check box for "Delete the driver" empty and click on OK.

    click OK

The display driver will disappear from device manager. Close all the windows and restart the computer. The computer will boot up to normal windows and the display will be fuzzy or blurry. Windows will automatically reload the video driver and the computer should restart on its own. Once the computer is back up into windows, you will be able to set the resolution correctly for your monitor if it has not done so automatically.
