Wireless Switch Icon missing on Vista taskbar... wlan quit working

Last Modified: 2013-11-12
New Sony laptop (VGN-SZ430N) running VISTA Business.  Configured box for client last week and wlan conectivity AOK.  Now the "Wireless Switch Icon" (from VISTA help screen) is not visible on the taskbar and wlan light is not on even though the wireless switch is toggled.  I've checked and reset all the power setting for the wlan per Microsoft KB articles that I've found to no avail.  I suppost it's possible that I've got a hardware failure but the switch does turn on the Bluetooth and wwan lights, just not the wlan.
Is there a Service or a command line function to force the wlan on?

Can you open the Network & Sharing center and enable the connection from there?



Yes I can open the Sharing center but have no apparent way to enable the wlan from that screen.  If I click on "View full map", the wireless adapter message is: "The adapter is not connected."
I feel like a dog chasing its tail.  If I had my druthers, (that's southern for preference), I'd start using VISTA sometime in 2009.  Any further suggestions since we are saddled with this lovely OS?

It says is working proprely.  If I uninstall it, it reinstalls appropriately and indicates that everything is just peachy.

I can disenable/enable the adapter and it looks like it's working but the wlan light remains off in either case and the system reports that the adapter is turned off when it is in the enabled mode.
Looks like I've got a hardware failure on the new box.
