Dell XPS 15 7590 Killer WiFi Network Adapter Issue

Hi Everyone

I have purchase brand new Dell XPS 15 7590 in January 2020 this year. Since the beginning my laptop is occasionally disconnecting from WiFi. Currently to the point where even rebooting the machine won't fix. The Killer(R) Wi-Fi 6 AX1650x 160MHz Wireless Network Adapter cannot start. From last 2 months I have done every possible solution dell technician suggested but none of them resolved the issue that includes.

1. Reset BIOS

2. Run Diagnostic Test from web, supportAssit and Boot Menu - Everytime Passed

3. Install Latest Drivers and Windows Up-to-Date

4. Uninstall Network Adapter, and re-install "Killer-1650-1435-1435s-1535-WiFi-Controller-Driver_1847J_WIN_2.1.1359_A12_01" from https://dell.to/2WycjZm

Upon my personal investigation I found alot of dell customers reported same issue, and it's problem with Killer WiFi Network Card.

Before you suggest I have tried all solutions from, and nothing works:

1. https://www.dell.com/community/Laptops-General-Read-Only/XPS-15-9560-Killer-Wireless-killing-my-netw...

2. https://www.dell.com/community/XPS/XPS-15-7590-disconnecting-Wifi/td-p/7365191

And now dell tech team suggesting me call their paid software support team. Does dell really expects customer to spend over $2000 on brand new Dell XPS which can't connect to WiFi, and then call their paid support to resolve it? That is unacceptable, and I did not expected such low level of service from Dell. Highly disappointed.

I am consider this option at this point (Buy myself a Intel network card, and replace it crappy Killer card)

I have a Dell XPS 13 and have the exact same issue. Tried everything you listed and finally called the customer service. Same response from the dell rep. This is ridiculous! You thought you bought a high end dell computer and this happened and they want you to call their paid software support team? It's only been a bit more than 3 months and you cannot get consistent WIFI connection with their KILLER Wi-Fi card, and they are not taking responsibility for this? And why does DELL keep using the KILLER Wi-Fi card knowing there are so many complaints about it already for the past 3-4 years? This is totally unacceptable coming from a reputable company like DELL. I have searched internet for a solution to this and found out that many people can resolve this issue by changing out the WIFI card. But after some more research, I found out my XPS 13 cannot even have the WIFI card replaced!! I've been using DELL computer for my personal and business use (maybe had 12 DELL computers/laptop) and a royal customer. Now I am really considering other brand for my computer/laptop choice. What am I suppose to do about this??!!

I just bought an XPS 13 a few days ago and its ridiculous how many times i got kicked out of zoom calls because my internet kept dropping! 

Now, after reading how common this issue is I am going to return the laptop. Why should I bother trying to work all these steps out for a day old laptop??? It is ridiculous. I am so livid about this. Mac here I come.

I had these issues as well so I replaced the killer card with an intel ac-9260 card and haven't looked back. I did see a post by fellow dell forum member AdrianG001 suggesting the following:

* 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

I can't comment if this is a fix as I've never tried it myself.

I wish this forum didn't alter the formatting in my reply above.

I understand you're disappointed as the issue is not resolved yet. I assure you that I'll do my best to make this as quick as possible. I’m confident our troubleshooting is on the right track and we'll reach a resolution without unnecessary delays.
