If a Windows XP-based computer has a wireless network adapter connected through a universal serial bus (USB) connection, and the computer resumes from standby or hibernation, the wireless connection icon may appear in the notification area (at the far right of the taskbar) with a red X and the following message:
Wireless Network Connection
Wireless Connection Unavailable
Even though you receive this message, the wireless network connection may still be active and functioning correctly, and therefore you may still be able to successfully connect to network resources over the wireless network connection.


Under certain conditions, the Wireless Zero Configuration component may indicate that device disconnection has occurred (because of computer hibernation, for example), but not that a device connection has occurred (after the computer resumes).
