Go to dells web site and get your drivers you will have to have the service tag # on the bottom.

You need to get the chipset driver maybe Bios update.

The reason it isn't working is you don't have a PCMCIA controller.XP Home edition doesn't have the extensive drivers as Pro.

I am using XP Pro

I spoke to Dell and they told me the chipset driver is on the Intel site. I could not find the relevant driver which is a painus in the anus.

Beginning to wish i hadnt started this

Thx for the reply

Paul

Look on the bottom of the laptop and see what the service tag # is and go to dells site or post the # and i will find them.

THank you, i will do that tonight

Hello,

My name is Richard; I work for Dell's Online Community Outreach here in Round Rock, Texas. I wanted to post to your thread with some information that may assist you. If you go to this link http://support.dell.com/support/down...n&catid=&impid=, you will be able to locate all the drivers related to you C400.

One other thing to keep in mind, it is sometimes best installing the drivers first then install the PCMCIA card into the slot. It is possible that the system can't even see the card and thus why Windows can't detect it properly. To check this go to the device manager, look to the bottom "other devices" category. Look for PCI device, while the card is in the system. Then do this again when the card is outside the system. This will help you determine if the PCMCIA slot is working even if the drivers are not installed.

Please let me know if you have any other questions. I can be reached at customer_advocate@dell.com, place attention Richard in the subject line.

I cant find the TAG number anywhere. I have looked and looked to no avail.

Any ideas how else i can get the TAG number ?

Cheers

Paul

it should be shown in the BIOS, otherwise its a black sticker

Okay, I found the TAG number in the BIOS, so thx for that, but can't see any chipset driver and I am still without wireless.

I might just go and buy a USB wireless stick

Any other ideas please ?

Paul

Make sure that the Wireless card is enabled in BIOS or the PCI slot is on. Could also be duplicate drivers. Try removing all of the PCI and Network adapters from Device manager in safemode and then resart the system.
Hope that helps
