Put this in my Dell XPS 15 9570 immediately upon receiving the laptop. The Dell supplied Killer card is bollocks so replace it with this. Intel network cards always work and are compatible with everything.
PS: If you're looking for a Linux distro that will install on an XPS in a trice and with zero error or effort, then look at Pop!_OS.
I, like many, have suffered the shame that is Killer Wireless on my XPS 13 on what was sold as a premium laptop from DELL. constant drops, poor performance even blue screens I decided to take the plunge and replace the WiFi card.
The card is tiny and came well boxed but with little instuctions. Youtube is a wonderful thing and shout out to Tyler Miller for a easy to follow guide. Once I researched the process then removing the back of my XPS replacing this was simple. Remember to power off and you can remove the battery connection but if you are careful it isn't necessary. Beware of the antenna connections they need care removing (they just pull off). Once removed the old card can be safely slid out and the new Intel card fits snugly. Replacing the antenna needs a small pair of pliers to squeeze down to firmly seat the antenna plugs. Re attach the guard plate and screws put back on and away you go. Laptop (Windows 10) rebooted detected the card and was working out of the box. Bluetooth and WiFi now reliable, stable and didn't need Intel drivers but you can if you want the control app. DELL should hang their head in shame for not fitting these as standard. Don't forget to remove the old Killer software. Definitely an excellent buy and at this price was a bargain.
This is a doddle to install - clip it into the slot on the motherboard and boot up. Windows 10 has a driver for this and it went in without a hitch. Unfortunately, it then proceeded to connect to my wifi with the weakest signal imaginable. I was able to rectify this by installing a separate wifi antenna, which unfortunately isn't quite such a straightforward installation. With the antenna fitted, the signal is strong and rock solid.
Installed it in my Dell XPS 9560 and it was terrible - took forever to access a website. WI-FI internet speed was ten thousand times worse than the old card even with new Intel drivers installed. I was just about to return it to Amazon and put the old card back in when I saw a YouTube comment that the white and black cables had to be switched - were on the wrong terminals - I switched them and VOILA! It worked. Bloody ridiculous that they manufacture and switch the antennae terminals.
I purchased this as a replacement for the Broadcom BCM43602 that comes with some Dell XPS models, while it wasn't "broken" in my specific case for my Dell XPS 9550 I run Linux exclusively and the Broadcom driver has issues with suspend/hibernation under Linux, requiring the driver to be unloaded and then reloaded to get things working which was getting annoying.
I ended up replacing the card entirely for better Linux compatibility and saw that many XPS 9550 owners had used the Intel 9260. The only downside to swapping the card from the original Broadcom one is the 9260 is 2x2, not 3x3, so there is now a spare antenna not connected, but this is the trade off for stable WiFi, versus having to hack about and implement various workarounds like disabling power management and such which never really worked for me.
I purchased the 9260 module to upgrade my Hades Canyon NUC, which ships with the 8265 and whilst perfectly usable was somewhat of a disappointment in an otherwise amazing system. I mainly got this for the Bluetooth 5 capabilities, but there was a significant improvement to the wireless signal quality after installing the 9260. Keeping all variables the same, I went from a link speed of 780 Mb/s with the 8265 to 866 Mb/s and a signal quality of around 65% to around 90%. Internet download/upload speeds were, obviously, unaffected but internal wifi speed and quality were noticeably improved. I run Linux and, as expected, this wifi card just worked without any fuss. Highly recommended if your laptop or NUC needs a wifi improvement or you simply need Bluetooth 5 functionality.
Bought this to replace the Dell factory supplied "Killer" Wifi card and just wish I had done it sooner. The Killer card would frequently disconnect and, as I always use a VPN, this would mean a double reconnect. This Intel card keeps the connection AND I now have blisteringly fast internet speed. I did not think the killer card was particularly slow until I installed this card. So, I couldn't be happier with my purchase. Just wished Dell supplied a decent card in the first place!
PS I suggest you download the drivers BEFORE you install otherwise you will need an ethernet connection to get them ;)
I bought a Dell XPS 8930 but frustratingly, Dell really skimped out on the standard wireless card they ship with, a Killer Networking / Qualcomm chip that uses really stupid drivers that are supposed to optimize your network performance but in reality often throttle download speeds as low as 0.5 Mbps and never higher than 30Mbps,
After weeks of trying to sort the issue, I looked a the spec and realized the wireless card was a removeable M.2 device so ordered this Intel one off Amazon instead. Fitted it on 10 minutes on my lunch hour, no driver installation needed, all the drivers are included in Windows 10, had rock solid 160 - 200 Mbps download speeds straight away.
If your new computer has similarly been fitted with a rubbish card, this is a great upgrade.
I have struggled to get this card working under Linux for months. Every main distro I have tried (Mint, Ubuntu, OpenSUSE Tumbleweed, Manjaro, BSD), even with the most bleeding edge kernels have failed to work reliably with this card. It will throw dmesg errors constantly, fail to load firmware, or simply not work at all. None of the googled workarounds have worked (dual boot win 10, disable fastboot). The only Linux distro that this card has worked reliably on was Clear Linux from Intel, but that has a package format that will have you downloading 1gb for a 10mb package! I've recently swapped it out for a £6 Atheros based card, which just works. If you're using Win10, it's fine. Linux - AVOID!
