Dell XPS 13 9360 Wifi disconnection and router AP crash Issues

Jump to solution

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

Changing the channel width in the Router Wireless settings to 20Mhz worked for sometime, now the router crash is back again. As mentioned in my earlier post the wifi connection on my laptop isn't crashing anymore though.

Should I change my router and if yes please suggest router models which work with Windows 10 / Killer 1535 / XPS 13 9360

Thnx

I have the same problem. 

XPS 13 9360 with the Killer wifi card.  Router is a TP-Link Archer C7.  The router crashes about 30-60 min after the XPS laptop connects.  None of the other devices on the network have done this, and none of the other devices have internet access until I power cycle the router. 

I've got updated drivers from October from the Killer networking site.  

A bunch of people on reddit have posted about the same issue:

I've had the same problem after receiving my XPS as well. I'm using a TP-Link Archer D7, so not sure if it is just a router issue.

Similar issues, in that my router will drop the AP, but also all wired PCs connected to it will no longer be able to access internet either.

Hoping a Dell tech might have some answers.

I have a same problem with brand new Alienware 17 laptop r4. it uses the killer wireless too. Dell do you have a solution??? using TP-link c7 router and verified the newest driver on the router. I also updated the wireless and Ethernet driver for the laptop too. I even tried a different router linksys still the Alienware is bringing the whole network down requiring a network reboot. all other laptops are functioning just fine including streaming video until the Alienware is hooked up. Interestingly, even if I turn the Alienware wifi off and hook it up by Ethernet cable I get the same problem. Need solution pls.

Like everyone else in this thread, I have the same issue. I have updated my Archer C7 (V2) to the latest firmware. I have tried the Wifi driver that Dell has provided on their website. Even wiped my system and then tried the driver that Killer Wireless has provided. The XPS 13 9360 still seemed to cause my router to crash.

I then decided to put Ubuntu 16.04.1 onto the laptop, and have not seen my router crash using either the 2.6Ghz or 5Ghz frequencies.

My guess is that something is up with the Windows 10 driver for this wireless card. I'm going to roll with Ubuntu for now.

After the Wifi disconnections stopped, I realized the issue was with my Router and Windows 10. So I switched to my old Dlink N150 router and post that I havent noticed any router crashes. So now I use 2 routers, the TPLINK for my other devices and the old Dlink for my brand new laptop. I notice slower browsing speeds on my new laptop but thats to do with my slower old router I guess.

Will upgrade to a dual band AC router soon and hope it will resolve my wifi issues.

I must admit, I spent too much time on this issue and it more or less killed any excitement I had for buying the "best laptop of 2016". I wish I had simply gone for the 2015 Macbook Pro and saved myself a lot of time..
