Hi. Just downgraded from vista to XP and for some reason my wifi won't work. it won't even turn on when I try manually (the little green lite is always off). bluetooth works fine though. I tried tinkering with the BIOS settings and even flash upgrading it- with no success. if you can, much obliged.
Try going to dell.com. Go to support/downloads and look for your product i.e inspiron 6400. Go to download drivers and choose operating system xp. then the rest is straight forward (look for your network adapter name)...pls note: i cant remember exactly where to go on the website but its under support. U should get u to the downloads page without any difficulty.
OR if u hav the Drivers and Utilities cd, use that to reinstall the device driver.

I am also having the same problem with my Sony Vaio VGN-CS21GN Laptop. WiFi was working perfectly in Vista but when I downgraded it to Windows-XP it started giving me errors that "Driver Not Found for the Device" I have downloaded all the drivers available on internet but nothing worked.
Finally after 8 months of research on this problem, I came to know that there is a bug in the supplied Windows XP-SP3 Operating System. There is a file in Service Pack 3 that doesn't allow drivers to access the hardware of WiFi.
The Solution is you will have to forget the bundled windows XP and upgrade your operating System. Right now better option is to go for windows 7. It dint even asked for any kind of drivers to load. WiFi is also working perfectly on it. The laptop has become more faster & smoother than in windows XP.
For more queries, you can write to me on email@example.com

Uninstall any wireless drivers for have incorrectly install in device manager. Reinstall the Chipset driver over whatever is installed and then reboot. Extract the 174291 driver into a folder and manually install the wireless and it should work
You may find that the WiFi card needs new drivers. Some particular wifi adapters don't have XP drivers. Compaq are now owned by hewlett packard so go to www.hp.com and search for XP drivers for your wifi card there - luckily HP are very good for providing drivers for XP even on Vista-supplied systems.
Please Check in device manager, is there any problem with the driver ?
if there is a problem with driver, try to download driver from www.acerpanam.com and install it.
if there isnot any problem, try to enable wireless from the switch (close to external audio port)
Often, yes most if not all of the drivers are available from the net. To be safe, pls post back brand/model of your PC, the devices such as video card, NIC, WiFi, Sound, etc. All of these may be found in your Hardware/Device Manager.
Hope this be of some initial help/idea. Post back details as requested and will work from thereon.
