From Microsoft..... Windows 7 RTM Explorer Crashes when Connecting Wireless LAN From the tray icon By Marius Oiaga, Technology News Editor 8th of January 2010, 12:13 GMT Adjust text size: Microsoft explained that, under certain conditions, Windows Explorer in the latest iteration of the Windows client might crash when users attempt to connect a wireless network. According to the Redmond company, customers that have come across this issue indicated that the crashes were caused by nothing more than simple attempts to connect Wireless LAN from the tray icon. In this scenario, Windows Explorer will crash, only to subsequently restart. At the same time, an error message is stored in the Application log. Users will be able to find the message at the bottom of this article, or on Microsoft Support. â€œThis issue tends to occur when you select a Wireless LAN from 5 or more access points. (â€¦) This problem occurs because the message handling for Wireless connection is not fast enough and causes overflow in the message queue,â€ Microsoft explained. The Redmond company has even documented the necessary steps to reproduce the problem. Users need only to click one Wireless LAN connection from the tray icon and enter the Security Key in the connection dialog window. Double clicking the OK button will cause Windows Explorer to crash and restart. Microsoft doesnâ€™t yet have an update designed to resolve the issue. The software giant isnâ€™t even offering end users affected by the glitch a hotfix to help them out. However, a workaround is available. â€œTry reconnect to Wireless LAN again after Explorer automatically restarts. Trying in a place where there are less than 5 access points is more successful,â€ Microsoft noted.
