Dell Latitude e6400 WiFi Disabled after every reboot

I have a Dell e6400 laptop with an odd problem...
After any reboot the wifi adapter is disabled.
Simply enabling it seems to solve the problem until the next time it is shutdown.
All drivers and BIOS are up to date, and it is running Win7-64bit.
I have tried removing the WiFi adapter from the device manager and reinstalling using the current Dell drivers, but with no success.
The WiFi adapter doesn't use any special app to manage the connections, it just uses what's built into Win7.
Wired networking works perfectly.
The user of this laptop is not very technical is would like it to just work, without the hassle of finding and enabling the adapter every time he starts up.
Any suggestions?
Thanks,
Ken

Check the 'Network Connections' server in Services under Computer Management. This server. Restart the laptop and check to see if the service is started or not. If the connects are not starting the server try and set the service to automatic from manual. You can also look at the 'WLAN AutoConfig' service... These are the only two things that I can think of that would be causing this issue.

Yup, I checked all the network and wifi services.  All start normally and continue after restart is complete.

I started turning off start-up items one by one (MSCONFIG > Services > Hide all MS services to avoid turning off anything really needed, then start unchecking things one at a time.)
I discovered that one of the Dell system management utilities was causing the problem.
I left it disabled, and have not found any ill effects from doing so.
This, of course, took several hours of rebooting, but it finally revealed the problem.

Although the other suggestions were appropriate, they were all things that I had already tried.
