After you wake a Windows Vista-based computer from sleep or from hibernation, you experience the following symptoms:

• The network icon in the notification area at the far right of the taskbar is not updated to show the connectivity status of the computer.
• If you connect a network cable to the computer or if you connect to a wireless network, the network icon in the notification area incorrectly shows the connectivity status as disconnected.
• If you move the pointer over the network icon in the notification area, the Currently connected to ScreenTip does not appear as expected.
• If you click the network icon in the notification area, the Currently connected to ScreenTip does not appear as expected.

Note: In this case, the expected ScreenTip should contain a Connect to a network link and a Network and Sharing Center link.
You experience these symptoms even though you can successfully connect both to wired networks and to wireless networks.
