Three kinds of downloads are available on Download Center for Intel® Wireless Adapters:

For Windows* OS:

1. Automatically detect and update your drivers and software with the Intel® Driver & Support Assistant.
2. Manually identify your Intel® Wireless Adapter and driver version number. Then download the latest driver for your Intel® Wireless Adapter.
3. For driver-only package, see IT Administrator Links for Intel® PROSet/Wireless Software.

See Linux* Support for Intel® Wireless Adapters for more information about Linux* drivers.

To manually install your drivers or Intel® PROSet/Wireless Software:

1. Ensure that the download supports your wireless adapter.
2. Download the file to a folder on your PC.
3. Double-click on the file to launch installation.

Your computer manufacturer might have customized drivers and software to enable or alter features, or provide improved operation on your computer. Contact the manufacturer for the latest updates and technical support information. If you can no longer get driver support from your computer manufacturer, you can download generic Intel drivers.

I've tried to Install an Intel network driver for my laptop. It's Intel 825xx 10/100/1000 Ethernet Controller Driver Version: 18.1.0.0 ,A08 (I got it from the Dell Support Website which told me this was one of the drivers fitting my device).

According to the log, it fails with:

Installation was not successful. The most likely cause is no supported network connection exists on this platform.

What's that supposed to mean? Do I need to plug a LAN cable into the LAN adapter, so that a network connection can be established before the driver will install properly? Or is the LAN network device out of order? Or something else?

I've tried that on Win7 and (following automatic upgrade) Win10 - same error all the time.

I further tried installing with 'Intel Device Manager Diagnostics Utility' available from the same website. It said it installed nothing since no network connections existed and no Intel adapters were found.

Edit: Additional info as requested by first three comments:

• It's a Dell Latitude E6420
• Listed under Device Manager > Network Adapter is a Intel(R) Centrino (R) Ultimate-N 6300 AGN. According to it's properties it's working fine.
• The full configuration is at: http://www.dell.com/support/home/de/de/dedhs1/product-support/servicetag/CXX92Q1/configuration and I suppose that list is up-to-date as told to the website by the Dell System Detect utility. The list of network adapters is empty. It's a Intel(R) Core(TM) i7-2620M CPU @ 2.70GHz CPU with NVIDIA NVS 4200M GPU, BIOS Version A04. Please ask if further info is needed.
• Device Manager lists three (3) devices with exclamation mark signs. Their IDs are: 1.) (unknown device, saved at: 'Stammkomplex für PCI-Express') ACPIVEN_SMO&DEV_8800 ACPISMO8800 *SMO8800 2.) (Broadcom USH, saved at 0000.001d.0000.001.008.000.000.000.000) USBVID_0A5C&PID_5800&REV_0101&MI_00 USBVID_0A5C&PID_5800&MI_00 3.) (mass storage controller, saved at PCI-Bus 11, Gerät 0, Funktion 1) PCIVEN_1217&DEV_8231&SUBSYS_04931028&REV_03 PCIVEN_1217&DEV_8231&SUBSYS_04931028 PCIVEN_1217&DEV_8231&CC_018000 PCIVEN_1217&DEV_8231&CC_0180
• I've spoken on the phone to Dell support (on an ordinary phone number - they spoke to me for about 30+ minutes even though there's no more warranty on this device). They suggested I downgrade to Win7 (despite the same problem occuring when using Win7) and try to install the driver/s there. In passing they mentioned that maybe there was an issue with the network adapter itself or with its plug that connect it to the mainboard.

Network Controller Driver Won't Update Windows 10

Had the same issue on my Latitude E6430. Turns out, that the network card was disabled in the BIOS. Obviously, the operating system had no chance of detecting the Intel(R) 82579LM Gigabit Network adapter.

Once, I turned in on there, Windows automatically installed the required drivers.
