Can you tell us the version of drivers you are using?

Have you tried uninstalling the device and checking the box to uninstall all drivers, then loading the latest drivers, which I get directly from Rivet Networks..?

Hello. We are awaiting your response. Do reach out to us so that we can assist you further, until then we shall be temporarily archiving the case at our end. ^MP

The same thing is happening to me. I have tried everything. Using Killer software uninstaller, Manually multiple times device uninstalling until it does not appear and so on. The last 2 times this happened to me I was able to solve it uninstalling OpenVPN (TAP windows Adapter)  removing the device and restarting the laptop. I'm not able to make it work now no matter what!  

Windows version 1909

This exact same thing is happening with my XPS-13 which is less than a month old. I have uninstalled and re-installed the driver from the Dell Support center, but it does not work. Did I just buy a $1500 computer that won't connect to wifi? 

UPDATE:

After my own attempts to uninstall and re-install the driver, I called the main customer service line and received immediate help from someone named Parmeshwar. He did a *clean* uninstall of the driver for me (and taught me how to do it), then he walked me through a clean install via the Dell Support driver page.

Then he had me go into the Bios to restore the driver defaults, and when I restarted the computer a final time, the issue was resolved. 

I don't remember all the steps well enough to detail them here, but it seemed to work, and I was honestly impressed with the level of service. (The entire phone call - including one transfer to get me to tech support, did take about 45 mins. But I was not waiting on hold very long at all.) 

I have just experienced this problem on my XPS 13 7390 after a  Windows 10 Home update (1909). 

After a lot of trial and error, here's what I did to fix it . (Clean install).

1. Go to https://support.killernetworking.com/knowledge-base/clean-install-killer-control-center/ and download the Killer Software Package Windows10 1803+ and the Killer Uninstaller .
   
   
2. Execute the Uninstaller to REMOVE Killer Software . (Once this is complete you do a SCAN to check the software has been removed .)
   
   
3. Go to Settings-Apps & Features and remove any remaining Killer Apps . (I had a Bluetooth driver ).
   
   
4. Reboot pressing F12 to load the BIOS Editor  and execute System Repair . Reboot.
   
   
5. Install Killer Control Center downloaded in step 1 . Reboot .

Probably won't work for everyone - but  Good Luck anyway !

We had exactly this error with an XPS 13 7390 2-in-1. In Device Manager the Killer AX1650s network device (driver version 21.90.2.1) could not start.

In the system Event Log appeared errors from ACPI indicating that a device driver was trying to write to the wrong area of memory. The BIOS update by Dell Command Update to 1.5.0 must have failed somehow.

We reflashed the BIOS with the same version again and watched carefully: no errors. On rebooting, the wi-fi adapter immediately started without error and connected.

Thank you to Ognyan at Dell Tech Support.

Thank you Tafti, this post resolved my Issue.

I'm on a XPS 15 9500 and my WiFi adapter just stopped working with a Code 10 in the Device Manager. When I checked the Windows Event viewer I saw this log of problems:

Netwtw10 error:

Netwtw10 Error

ACPI Error:

ACPI Error

First I tried a clean reinstall of the drivers following the Killer advice here: Wireless Not Working After Update / Code 10 Error – support.killernetworking.com

To no avail. Then I found the post above, did a clean Uninstall of the Killer software/drivers as per the Killer advice, then reflashed the BIOS by downloading the latest version from here: 

Product Support | Dell UK

Then running it and following the instructions. 

When the Laptop rebooted after the update, the WiFi adapter worked instantly without needing to install any more drivers.

So I just experienced this issue with my system, an Aurora Ryzen. I went through the steps listed in previous comments with no luck. I contacted support and we did update the bios but that didn't yield any results. As a last ditch effort, before resetting back to factory defaults, we deleted the device from Device Manager and immediately shutdown the system. I then powered off and unplugged the system and popped the wifi chip on the motherboard for about 30 seconds. Re-inserted the chip, closed the system up, and powered back on and wifi started working.

I wouldn't recommend doing this if you aren't comfortable going into a system. 

Another thing to try. I have an XPS 9530 with the Code 10 error installing the Killer WiFi driver.  The laptop was plugged in to AC power during the failed installation.  I disconnected the power cord, uninstalled the driver, then reinstalled it.  The installation completed successfully.  That looks suspicious, as during a BIOS update the system needs to be plugged in.  Installing the two drivers together would be a problem if the issue is a bug in the driver related to the power source for the laptop.  

Hi,

How do I reinstall the driver after uninstalling? 

I have run in to the same issue and I'm not sure how to reinstall if I uninstall the driver

Thank you

I had the same problem. I uninstalled latest windows update and restarted the machine. That resolved the problem. But I am afraid the problem might reappear after auto install of windows update.
Any suggestions?

@Saltgrass​ I had tried several times to Uninstall w/out removing drivers. This time I did the "remove drivers" and rebooted.  The WiFi is now working.

Thanks

It's a bios bug.

I had the same problem. did a bios update from "Dell command update" app , all good. 

Didn't need to reinstall or update any wifi drivers.
