XPS 15 L521X ....Latest Problem
So I updated to Bios A09 hoping it would improve either my Wifi issues, my throttling issues, or my battery life issues.
After the A09 update, my nVidia Graphics chip is no longer recognized, and therefore have lost my dual external monitor support. That may improve battery life I guess since the nVidia chip is now worthless and I'm forced to the Intel 4000. Not the change I was hoping for.
Is it possible to revert the A09 bios back to A06? Is this isolated to me, or was it just not QA'd at all by Dell?
I worked around the wifi issue with a USB dongle, and am living with the battery life issues by getting less work done on airplane flights.
Losing my multi-monitor support is killing my productivity. Also losing my patience with this machine and Dell in general.

It's completely different design. Nothing is comparable except the names.

It really works!
I have XPS 15 L512x system with Win 8. It was not possible to use internal wifi in range that exceeds few meters from AP. But now, after I followed your advice, wifi works perfectly.
At first I removed both drivers and restarted computer. Then I installed nVidia driver file Video_nVIDIA_W74_X15_A01_Setup-WXGWV_ZPE as you suggested. It was made for Windows 7 but works fine with Windows 8 also. Then I installed newest wifi driver downloaded from Dell support site. My laptop has different wifi hardware so I had to use different driver. Restarted computer and... VOILÀ - wifi problem is gone!!! THANK YOU!
Still wondering, if this is just driver problem as it seems to be, why Dell is not able to fix it during so long time?

That's great that it worked for you too. It looks like a driver issue for you and me, but I don't know if that's the case for other people. There may be a genuine issue with the hardware design itself for other customers. Even though its performing better after I performed those steps, WiFi is still not as good as my other laptops.
