I received my new Dell XPS 13 9560 PC, powered it up, and immediately it began crashing my wifi network. This happened repeatedly and would occur anywhere between five minutes and one hour after powering up. Every time this happened, I would have to go to my loft, where my router is, turn the power off and on and wait for the network to come up again. Given I live in a rural area, and use the wifi network for my phone, not only did I lose internet service when this happened, but phone service as well.   I was confident the new PC was the cause of the problem, since I’ve had my TP-LINK Archer C7 AC1750 Wireless Router for two years and never experienced this issue using our household’s other two computers: a high-end Mac Pro and a $200 HP Stream 11.  Plus, many friends and family have visited me and used their devices with no problem. So, I reported the problem to Dell Support. For four days, they had me installing various drivers and BIOS upgrades. They even had me upgrade the firmware in my router.  Meanwhile, I’d been researching the issue, Googling “Dell XPS 13 9560 wifi issues” brought up an article from Windows Central, “Having Wi-Fi issues with your Dell XPS 13? Here’s how to fix the problem.” The article went on to state “One small complaint about the stellar Dell XPS 13: The stock wireless card ***.” Their recommended solution: replace the stock Rivet Network’s “Killer” wifi card with the Intel 8265NGWMG wireless card.  For those of you out of warranty, it’s available for about $30 from Amazon. The article takes you step-by-step through the replacement process. Quite easy if you’re careful.  In my case, with my new PC, I didn’t want to risk voiding the warranty. On Day Four of my email and phone interactions with Dell Support, I brought up the fact that I had done some research and had found this article, plus many forum comments pointing to the Killer wireless card as being the culprit. Immediately, they agreed to have a technician drive to my house and replace the stock Killer wireless card with the Intel 8265NGW.  It took the technician only a short amount of time to replace the card, install the driver for that card and hand me – at last – a working Dell XPS 13. Now, several days of usage later, the network has yet to fail.
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 : InactiveWakeOnMagicPacket : 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
