Dell XPS 13 9360 Wifi disconnection and router AP crash Issues

This question has suggested answer(s)

Hi All,

I received my brand new Kaby Lake powered Dell XPS 13 9360 a couple of weeks back and I have been suffering from wifi disconnect issues since then. The USB LAN connection works perfectly using the Dell USB C adapter.

I have tried all the standard troubleshooting steps:

1. BIOS and Killer 1535 Wireless Adapter Driver updated to latest version  (including uninstalling and reinstalling the wireless drivers)

2. Updated Windows 10 to the latest anniversary edition

3. Changed Power Saving settings on the Wireless Adapter using Powershell commands as there are no Power management options for the Killer Wireless adapter in Device Manager 

(Disable-NetAdapterPowerManagement -Name "Wi-Fi" -NoRestart)

After running the above command I get the status of the relevant power mgmt parameters as below (though not sure if its really effective)

DeviceSleepOnDisconnect : Inactive
WakeOnMagicPacket : Disabled

 4. Installed the latest Intel PROSet/Wireless Software and Drivers for Windows 10

Even after running step 1 and then later step,2 the wifi connection used to disconnect after some time (especially when a large file was being downloaded or any high network usage activity). Running a speed test of my broadband connection is a sure way to disconnect from wifi. More importantly this disconnection used to crash the Access Point on my TP-Link WR841N router which caused all my other devices to lose network connection as well and required a Router restart.

After steps 3 and 4 I have noticed the Wifi disconnections are not happening any more (atleast for now), but the Access Point crashes continue as it is, so effectively the wifi does not disconnect but the router AP crashes and needs a Router restart.

So my question to you all is do I need to change any config on the Wireless setup of my router to ensure the AP does not crash, or the should I change my router and get an AC router. If the router might not be the issue then it might be due to Windows 10 and the known issues with the Killer 1535 Wifi adapter itself.

I tried changing the Channel Width to 20 MHz but it reduced the network bandwidth and gave me 1/3rd of the available speed. 

Any help and pointers especially keeping my specific router issue in mind would be much appreciated.

Thanks

  • Still no solution available - Killer Networking updated their drivers on Feb 20th according to their website:

    www.killernetworking.com/driver-downloads

    I have one of that Killer-1535 cards installed in a Test XPS13 9350 which was still shipped with a properly working DW-1820a.

    Replacing the card renders this Model useless, even switching to that mentioned driver from a clean Win10 installation still leads to the usual timeouts. The drivers shipped in that package have a timestamp of Sep. 21th 2016, so they have not been updated at all but are at least 5 month old. So unlikely something (positive) would happen here.

    The "Solution" which is marked "Verified Answer" here multiple times - come on, thats more a joke.

    Forcing the Wifi card to operate on 2003s IEEE 802.11g cant be taken serious.

    You also wouldnt consider "Install WindowsXP" is a proper answer.

    Dell should either make sure there is a proper driver available for their Hardware, or switch the Vendor.

  • There are two issues here. There is a "Wifi Disconnect ONLY" Issue people are experencing. The new drivers above are spose to fix that issue.

    The 2nd issue is the "AP/Router Crash Issue" (with the TP-LINK Archer C7 and other routers). This issue people are experencing is not solved with the new drivers.

    The above drivers are dated when I install them: v12.0.0.296,  Feb 12, 2017

    www.killernetworking.com/.../other-downloads

    I must admit I been very impressed with Killer Support, when I talk with them. Very responsive and knowledgable. That said, I am glad they are fixing issues, and glad the Wifi Disconnect issue is solved (I never had that issue). The Router Crash Issue is still present in the new drivers though. And talking with support, they do not have the hardware yet to even reproduce the issue. They are working on trying to solve that, but I assume it'll be a while until they have all the hardware nessasary to reproduce the issue, let alone start making a fix. Eventulally router firmwares will be patched, and Killer won't even be able to reproduce the issue, so nothing will be done to see how the Killer Card is misbehaving... TP-LINK is working on updated firmware and it's beta has been released (haven't been able to test since I am on OpenWRT/LEDE currently - which still has issues). Not too sure about all the other routers firmwares which have issues.

  • Thanks for that tip - yes those drivers from the "Driver only" Package are indeed newer ones):

    (old: 2016-08-30 / v12.0.0.279, new: 2017-02-12 / v12.0.0.296).

    Unfortunately they dont change anything to our stability problem, this is still the same. (tried different settings to Preferred Band, Roaming Aggressiveness, only enabled n/a/ac (so disabled b+g), there is just no change - i have to actively search for a place where this laptop works halfwhat ok when using the Killer 1535.

    Below: 10.0.101.179 the laptops IP, 10.0.100.1 is its gateway.

  • Hi folks - we have just posted a new wireless driver and software suite that addresses a known issue on a small percentage of systems where the Killer Wireless module will drop the WiFi connection when passing a large amount of traffic. We have worked closely with Microsoft on this, and have identified a fix. This fix has been confirmed with several users that currently have the issue and we have posted a new software package. Please visit the link below to get the new driver:

    www.killernetworking.com/.../e2200-e2400-wireless

    This fix will not resolve issues related to the router misbehaving, as that is a router specific problem, however if the issue was specifically with intermittent WiFi drops related typically to heavy traffic, the above should address that.

  • Thanks for the update, unfortunately doesnt change anything here.

    Apart from the contained Software - can you confirm the driver itself is still the same as in the Driver-Only - Package above?

    The driver version displayed on my machine is unchanged: 2017-02-12 / v12.0.0.296

  • Hello,

    I have just bought a top of the line XPS 15 9560 with the Killer 1535. Since day one I have had issues using this machine connected to wifi. I have constant issues with disconnections whilst using RDP, Skype calls etc.

    I just installed the package you linked to, restarted and still having issues. If you need me to check something, test something please let me know as I cannot use this machine as it is!

    Thanks,

    David

  • Has anyone had a technician fix the wifi hardware and still face the same problem?
