The icon in the notification area (at the far right of the taskbar) for a wireless connection may show the connection as "Unavailable" after you resume your computer from standby, even if wireless connectivity is available.
This problem occurs because the media connect action is not sent to the Wireless service correctly.
Disable and then enable the wireless network adapter. To do so, follow these steps:
Start the Network Connections tool in Control Panel. Click Start, click Control Panel, click Network and Internet Connections, and then click Network Connections.
Right-click Wireless Network Connection, and then click Disable.
Right-click Wireless Network Connection, and then click Enable.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
