If Windows Update doesn’t find the driver or you want to ensure you're using the latest version, you can manually download and install the driver from Dell's website.

Visit the Dell Support Website: Go to Dell Support.
Enter your service tag or select your device manually. If you don’t know your service tag, you can typically find it on the bottom of your laptop or inside the BIOS.
Once on your device's support page, navigate to the Drivers & Downloads section.
Under Category, select Network or Wireless.
Look for the Dell Wireless 1397 WLAN Mini-Card driver (or Broadcom driver if listed). Choose the driver compatible with your version of Windows (e.g., Windows 10, Windows 7, etc.).
Download the driver package and run the installer.
Follow the on-screen instructions to complete the installation.
Restart your computer to ensure the driver is properly installed and active.

Method 3: Using the Driver CD (if available)

If your laptop came with a driver CD or you're using a system that has one, you can install the driver from there:

Insert the driver CD into your laptop's optical drive.
Open My Computer (or This PC), and navigate to the CD drive.
Run the setup program for the Dell Wireless 1397 driver.
Follow the installation instructions and restart your system when prompted.

Method 4: Using Windows Device Manager to Manually Install the Driver

If you have already downloaded the driver manually, you can install it directly from Device Manager:

Right-click on the Start Menu and select Device Manager.
Expand the Network adapters section.
Right-click on the Dell Wireless 1397 WLAN Mini-Card (or any device with a yellow warning icon) and select Update Driver.
Choose Browse my computer for driver software.
Click Browse and select the folder where the downloaded driver files are located.
Click Next to install the driver.

Check the Wireless Service: Make sure the Wireless Network Service is enabled in Windows. You can check this through Control Panel > Administrative Tools > Services.
BIOS Settings: Sometimes, the wireless card can be disabled in BIOS. Enter the BIOS setup (usually by pressing F2 or Del during boot) and ensure that the wireless adapter is enabled.
