XPS 13 7390 disconnecting Wifi

I got since a few days a XPS 13 7390 with a Killer(R) Wi-Fi 6 AX1650w 160MHz wireless network adapter (200d2w), and since from the very beginning I faced issues with the wifi connection. Every 5-10 minutes the signal disconnects and needs to be reconnected manually. Other laptops -including my former Dell- are working perfectly fine with no stability issues. I would need some help here, as all the drivers seems to be updated.

Re: XPS 13 7390 disconnecting Wifi

Welcome to the Dell Community  @GedoG 

Killer brags about being the fastest networking WiFi there is.

It can be when it is stable!!!

But so many people have posted about the instability.

From what I can remember this is what to do.

Create a folder on your desktop and name it "Killer"

Download the latest driver from Killer and copy it to that folder you just created.

Then go to "Device Manager" and uninstall the WiFi card.

Check the box to "Delete the software for this device."

Then reboot.

After rebooting go to the folder you created and install the driver from there.

Re: XPS 13 7390 disconnecting Wifi

I'm having the exact same problem.

I got my first XPS 13 7390 replaced 2 days after I got it, and the new replacement is behaving exactly the same way.

I have tried the wifi connection on three different networks, all 1 Gbit/s fiber, where I get 300-800mbit/s with other devices (including my 3 year old cellphone). However, the XPS fluctuates 0-2 Mbit/s downstream and below 0,5 mbit/s upstream.... its awful

I've upgraded every possible driver (from dell's website) with no luck.... still waiting for reply from dell support.
