XPS 13 7390 2-in-1, Killer WiFi adapter issues

Jump to solution

My XPS laptop has the Killer Wi-Fi 6 AX1650 160MHz Wireless Network Adapter (201D2W) that's supposed to offer the "most reliable connections" (as quoted from their website) but it seems to always act up and disconnect without being able to connect to wifi again. It's able to detect the networks that it could connect to, but when I try to connect it either connects without access to the internet or just straight up tells me that it can't connect altogether.

I've had to run the windows troubleshooter multiple times to diagnose and fix the issue and each time it says there's a problem with the wireless adapter and resets it. This works for a while until I notice less than 10 minutes later that its glitching again. From what I know, I've already installed the latest drivers, etc. but the problem still persists.

My Wifi was connected but I was unable to browse correctly. It looked like the WiFi was disconnecting time to time. I found a fix for this issue. You must turn off "Advanced Stream Detect" in the Killer Control Center or Killer Network Manager.

* Click Windows icon
* Type killer
* Click Killer Control Center
* Click Settings
* Under System Settings, toggle Advanced Stream Detect to Off
* Click Apply Changes
-or-
* Click Windows icon
* Type killer
* Click Killer Network Manager
* Click Settings
* Remove the check from, Enable Advanced Stream Detect
* Click Apply Changes

Also having wifi dropping issues.
Thoubleshooter says "Wifi doesn't have a valid IP configuration".
As a workaround I set Preferred Band to 5Mhz. It lowers the speed but increases stability.
Dell technical support wasn't able to help with it, so planning to return my unit and stick with macbook.

Was having the same issue as others and like the recommendation given, turning off the "Advanced Stream Detect" setting in the Killer Control Center solved the issue for me. Thank You!!

I have the same problem with the XPS 13 9360.  Owned 4 Dells in the past.  As an intermediate solution I am using a USB network adapter. GADS!!!  Will replace card with Intel when I return from sabatical.

Will never buy another Dell again!
