problem resolved - i posted elsewhere as problem resolved- mutiple fixes found in a variety of places were to no avail, i replaced the 1395 card and broadcom drivers with a ten dollar on ebay intel card and drivers, problem resolved.  i will never believe dell is not aware of this fix, the blogs/posts on this problem are legion throughout internet.  hours and hours of frustration that could have been resolved simply by a simple disclosure.  i would have happily bought the replacement card long ago.
i have fought this problem for years, every time i have to reload laptop (frequently due to work) it is a toss up if the problem will occur.  when it does, most of the time, i keep returning to previous windows restore point and reloading drivers until it somehow (i can never pin down the sequence of load that causes it to go away) stops.  if i disable the card it stops immediately but i do presentations which require audio and wireless.  sometimes i reload over and over and over.  i googled the situation and there are countless reports of same problem.  my card doesn't allow me to disable bands (one solution proposed) and someone else suggested with the intel card the problem would go away.  does dell have a fix for this, if not will the intel card hopefully resolve my problem.  i am weary of going through this every time, my other machines (also dells) with different cards never have this problem.  i would appreciate any assistance.  thank you.  mark
