SYMPTOMS

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.
