Question about Dell Latitude C400 Notebook
The wireless card probably has the wrong driver. The drivers from the Dell support web page never seem to work.
The card, known as a 1350 WLAN Mini PCI Card, was actually made by Broadcom, and the Broadcom bcmwl5.sys driver will make it work.
Hewlett-Packard used this card in their notebook computers. Here is a link to the installation program. Windows will warn that this is not the right driver. If you bypass the warning, you can install the driver and make the card work.
Here's what HP says about it:
This driver supports 802.11i/WPA2 for a/b/g and certain b/g WLAN cards. For other cards, it provides Wi-Fi protected access (WPA) support. This driver also supports Cisco Compatible Extensions Program V4.0 features (software supplicant required) and provides support for "125 High Speed Mode" for notebooks with Broadcom 802.11g and 802.11a/b/g cards that support "125M High Speed Mode".

Go to Network conections and enable the wireless device. OR, you may need to open up the wi-fi door and check the model# on the wi-fi card, and type in the model# followed by 'drivers' in a Google search to acquie the drivers, too
