I have a Dell D800, with a DellTrueMobile 1300 WLAN internal wireless card.

 

Ran MS Update today and it installed a new Dell Truemobile driver.  Or at least it tried to.  But instead it looks like it put the TrueMoble device into a really bad state. 

 

1.   The device is disabled.  When I try to enable it, the driver attempts to install but the installation fails. 

 

2.  When I try to re-install the driver from Device Manager, it fails with a "File not found" error. 

 

3.  So I try to re-download the drivers from the Dell Website.  I have tried several Dell drivers, including the ones for 1300 and 1350.  These all fail during Setup with "Error Update 576 error has occured".

 

 

So now I'm stuck.  My wireless network is diabled, and I am not able to re-install the drivers.  Any suggestions for how to fix this?  I'm ready to toss this thing out the window...
