Hello,
sometimes I find 2 wifi icons in my dock I use for displaying the system tray. I don't have a 2nd wifi card and clicking the icon makes it go away. What is disturbing is that I have tracked down Explorer hang issues on logoff to there being 2 wifi icons: if there are, Explorer and a couple of other apps don't react on shutdown, if there aren't 2 icons: no hang.

frequency: every 3rd boot.
Will be great if the cause is found and the issue corrected!
Thanks!
Lars
