Killer wifi problems

So I am having numerous issues with my XPS 13 (9370). Whenever I am connected to my wifi I occasionaly get "DNS_Probe_started_no_internet" error. Wifi shows that it is connected, but I can't really use it. When that happens I have to manualy disconnect and reconnect and it starts working again. I had the motherboard replaced with no luck. Also, it is not a router problem, because other devices connected to the same router have no issues. 

Fixes I have tried:

1.) Clean reinstall (with the help of support tech) of killer drivers (both bare and of the killer's website)

2.) Manually setting DNS to google's

3.) Resetting the windows

4.) Changing wifi adapter power settings to maximum performance

5.) Changing wireless mode in advanced adapter settings in device manager

 

P.S. I can assure I am running latest bios and wifi adapter settings. Please advise me on what should I do?

Re: Killer wifi problems

Tried everything from your link with no luck. Also, the thread you posted about it is kinda dead with no folow up from Dell.

Re: Killer wifi problems

Well, some of these are just saying that the wifi is bad on their devices with no actual fix. Others suggest swaping wifi card. I would love to do that, but sadly on 9370 XPS it is soldered on to the motherboard, making it impossible to replace.

Re: Killer wifi problems

Are you running Chrome?  I have never seen the DNS message you are getting so just wondering if you know what is generating it?

If you are running Chrome or even Edge, have you tested by using Task Manager to end the task for those browsers?  Try another browser, like just IE to see if problems continue.

What type of DNS IP address are you showing normally?  One on your local router or one fed through from your ISP?

Does your ISP provide IPv6 access?

Since there have been no definite solution for the Killer Wireless situation, I am just trying to look into other areas which might be effecting your situation.  Even something as how you have the Connected or Disconnected standby configured may be involved.

Re: Killer wifi problems

Yeah, I have tried other browsers so I dont think thats it. It seems to drop connection on older routers, but then again only this laptop has problems connecting to them.

Re: Killer wifi problems

The Win 10 update today had a couple of Networking fixes so maybe it will help.

I just installed a Killer Wireless 1550 card (not necessary for normal installs) in one of my systems and so far it is working normally, as was the 1535.  I did use the drivers from the Rivet Networks site.  Drivers on all the cards are based on OS installs from before 1803 or after installing the build upgrade 1803 and later.  We are currently on the 1809 build from Oct. 2018.

Re: Killer wifi problems

Something else you might try is to set one of your other systems as a conduit and then connect through it to see if the connection would hold.  I would use the correct word for such a configuration but this site beeps that word.

Re: Killer wifi problems

Hi you might try going to msconfig - > services. Then disable all services that start with killer and qualcomm atheros wlan driver.

Then go to msconfig -> startup and disable all killer programs.

I believe dell uses this services to dynamically cache some of the content however there are some bugs with the services which causes some errors in video/music services.
