Eu tenho um problema semelhante com a conectividade sem fio Win7, ocorrendo de forma aleatória ao desconectar de uma rede e depois conectando a uma rede diferente. O ícone da bandeja congelaria. O problema parece minimizar quando eu fecho todos os aplicativos que usam a rede, como internet, unidades USB externas, etc. Também parece ocorrer menos quando usando o Gerenciador de Tarefas aberto na guia Rede para garantir que não haja tráfego de rede no momento da desconexão Conectando Pode ser que eu esteja dando tempo para que o estouro no buffer de mensagem não ocorra, a saber, o seguinte.
A seguinte explicação parece mais provável, e vou tentar a sugestão da Microsoft:
However, a workaround is available. Try reconnect to Wireless LAN again after Explorer automatically restarts. Trying in a place where there are less than 5 access points is more successful

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.
“This issue tends to occur when you select a Wireless LAN from 5 or more access points. (…) This problem occurs because the message handling for Wireless connection is not fast enough and causes overflow in the message queue,” 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 doesn’t yet have an update designed to resolve the issue. The software giant isn’t even offering end users affected by the glitch a hotfix to help them out. However, a workaround is available. “Try reconnect to Wireless LAN again after Explorer automatically restarts. Trying in a place where there are less than 5 access points is more successful,” Microsoft noted.
Here is the event message that’s logged in the Application log when this issue occurs, according to Microsoft:
