Did you download the drivers from the page I linked? You have not explained how the installations fail. You said you performed a clean install of Windows. Did you install the chipset driver(s)? If you did not, do so now, then check Device Manager.  If that doesn't help, try this: If the wireless adapter still doesn't appear in Device Manager, it's possible that this is a hardware problem. In that case, do this: Dell's manual has instructions on how to remove and replace the wireless card. Whenever touching components or working inside a computer, wear a grounded wrist strap, also called anti-static wrist strap, ESD wrist strap, or ground bracelet. It's a cheap and sensible precaution. Rest the laptop on an anti-static mat or at least a reasonable alternative such as corrugated cardboard.
Hi DELL, I have been going through so trouble to install my Wi-Fi and Bluetooth drivers. First I thought it was a problem with my windows 10, so I reached out to Microsoft ( which was far easy). They assisted patiently and found out that everything is fine. They said that problem is from DELL! Now, my service tag is expired and i have been trying for ages to reach dell support!!  WHY DO I NEED A SERVICE TAG FOR A SIMPLE DRIVER??????? I just need my WI-FI to work. Period.
