Dell XPS 13 9360 Wifi disconnection and router AP crash Issues

I am also having the same issue

Those "Killer Wireless" cards are a real problem here as well.

We use several XPS13 in a company, for years - now after the first new model arrived using a "Killer 1535". Trying all available drivers and 2 useless calls to Dell support i ended up replacing the card by a DW1820 which was shipped in previous models, and issues are gone.

The Killer 1535 just loses packets almost everywhere in two of our offices, its entirely useless without a proper driver. The person using the laptop reported the only real place it was working well was his home connection.

Our Access points are Ubiquiti Unifi, from >200 devices there is just one which doesnt work: that XPS13 with a Killer Wireless.

Today i learned from our Dell Sales Person i need to find another Model because all XPS13 are now equipped with that card, and it doesnt make any sense to order a model you know it doesnt work in advance.

If you search for older posts, there are a lot of references to problems with "Killer Wireless" cards in Dell Hardware, i dont understand why thats not addressed.

two Examples from this forum:

If you are using a European version of the TP-Link Archer C7 V2, you can solve the problem by installing the following beta firmware: (yes, it works!)

Don't you suppose that the European beta firmware would work on any Archer C7 V2?

I have a Dell XPS 15 (9550) with the same chip, Killer 1535, running Windows 10.

Had the same problem as above when running without any power source connected. My computer broke the AP and I had to restart it in order to get it to work again.

Changing the power saving mode for the wireless adapter to maximum power solved the problem for me.

I followed the instructions found here:

support.microsoft.com/.../you-may-experience-connectivity-issues-or-performance-issues-when-you-connect-a-mobile-pc-that-is-running-windows-to-a-wireless-access-point

(the same instructions applied for windows 10)

Good luck!

On the Dell 9630's, we do not have any other power saving mode other than "Balanced". Won't let us change with the method you posted. There is a post before which let you change power savings on the adapter itself. This didn't change anything though for the Archer C7 -> Killer router crash.

With mine, even with ac plugged in it acts the same way.

On the office direct to router (wifi) it drops much less (appears to be only when suddenly you push higher download (ex.: youtube 4 or 8K).

At home with a wifi AP (router ---- AP ----- XPS 13 9360), it lasts only the first minute or so. Can only use the same AP with other clients after power cycling the AP.

I keep readnig that with Intel card (instead of the Killer) this is permanently solved. Anyone confirms? Thanks, Xv

I am too having this issue with my Dell XPS 9360 and TP-Link Archer C60 router. I don't think the router is to blame, cause I can reproduce the error when connected to my phones hotspot. And when the Wifi crashes, it still works on my girlfriend's mac.

I am in contact with Dell and they will, if i proceed, send out a technician. But i suspect that this will not fix the issue. What shall we do!? This is so annoying.

What is WMM?

Just bought XPS 13 2 days ago. I am also having exact same problem. After 20mins to 30mins TP link router crashes and never comes back until and unless I manually restart the router.

I feel the same. A new 2017 machine which crashes my router every time i trasnfer a large file. I can't use this machine for work, which is why I bought it... I still use my 5 year old Acer. I know TP-Link is working hard on the issue. And Killer has great and responsive customer support, but they do not have a Archer C7, or any QCA988x chipset router to test on. So they can't get around to working on the issue until they have the hardware to reproduce it. Meaning, I think they will get around to it, but it'll be another few months...

I can't wait 2-3 more months and just have the laptop collecting dust in the meantime... No word on Dell even showing intrest in this issue. Either they need to provide pressure to Killer or replace the WiFi card with a $35 Intel one free of charge for those affected...

Can we at least have an official aknowledgement by Dell that they are working with the adapter manufacturer in order to fix the problem ?  It's a pity in 2017 to have such a buggy driver that prevent from transfering large files.  My 8 year old dell Latitude works without a hitch and my brand new XPS 13 keeps dropping the wifi connection...

I guess they will continuing acting like these threads reporting XPS wifi problems don't even exist!!! Shame on Dell and unlucky those who bought an expensive piece of PROBLEM!!!!  

I have the same issue, has anyone contacted dell customer service about their problem?  What do they say?

a workaround that works for me is changing Network Adapter Properties/Advanced Tab/Wireless Mode/03 - 11 b/g

but that cripples the wifi
