Hello, I have probably the same problem. I reinstalled the killer driver (i have now this veresion KillerDrivers_2.2.3212_x64.exe). Still keeps me disconnecting from wifi. I ran the diagnostics - but I can't attach the file. I got this message "The file type (.txt) is not supported."

How should I proceed? Thanks

Still same problem.

I ordered an intel 9260. This is the solution.

Reading around more, the AX200 card has a fairly serious ongoing issue. Various driver versions have been tried, connecting it to an AX router though will result in disconnects. Intel don't seem remotely keen on sorting the issue out. 

I'd suggest the 9260 replacement and stick the AX200 in a drawer in case Intel pull their finger out at some point. 

1 workaround apparently is to force the router and the card to use a low numbered channel (so... around 50 rather than around 120).

@Dr. Allan Thank you for your message on this matter, we apologize for the issues that you are encountering with your device. If you haven't already please make sure you have done the following: 

• Updated Bios
• Updated to latest Windows Update
• Updated Firmware on your network devices (Router/Gateway/AP)
• Performed Clean install, using the Uninstaller Tool to remove, and latest Update to install the latest Killer Software UWD.

We also have a Knowledge-base (see Part 2) that shows you how to disable the Killer Software, this helps due to the Windows Update might re-install over your current Killer Software Package.

Hello! This solution that you gave worked perfectly until some point. Now it doesn't - Wi-Fi is constantly disconnecting. Can you please recommend something else?

@Nekto_Dell Thank you for your message, and update on your issue. Can you please look at the following Knowledge-Base, and verify if this helps your situation. I recommend starting at #8 first and then working your way down the list. If you are still having issues then please submit a trouble ticket to our support team so we can assist you. Thank you for your time - Nicholas with Killer Networking.

knegi, 

Sorry about the inconvenience at hand. Let's work on the issues reported. I've replied to your private note.

Dell support is a joke. When laptop has WiFi connectivity issues, how dell support is adamant about fixing it remotely and not sending a technician to look into the matter. I have sent the pictures and videos as evidence but no help so far. 

It is really frustrating and this is last product i would be buying from dell and i will make sure every one know how lousy Dell XPS line is.

1. Color banding - how a product can be released which has such a faulty display quality.. 

2. Killer wi-fi. real killer.

3. Screen freezing - may be some blame goes to MS.

4. Clean reboot takes 5-10 mins. there you have fastest top of the line premium laptop from dell.

Please arrange a technician who can come and really fix WiFi, it is killing us.

@knegi Thank you again for your message, and feedback. Have you sent a support ticket into us by chance? I would love to help get your issue resolved if you could send one in that would allow us to help you with your device. Please submit a Diagnostic with this Ticket, and give us the information of your network at home (Router,AP, Gateway, ect) Brand and Name of the Device, last time you have updated is firmware. Screenshot of the Wireless Settings on your network device, or your Wi-Fi Analyzer page of the Killer Control Center. (Both 2.4GHz and 5GHz). 

We have found that some users have resolved their issue with this Knowledge-Base starting at #8.
