XPS13 9350 skylake no wifi on Ubuntu 15.10

If you go to Additional Drivers, is the proprietary driver enabled for broadcom? (If so in the future please always mention in your messages what you have tried so far).

Yes, I tried the additional driver on Ubuntu 15.10 via the UI, it doesn't list any additional boardcom drivers. I made sure I enabled multiverse repo.

I also tried manually installed bcmwl drivers, still no luck.

I've tried to understand what exact Broadcom card is inside the Dell and rebranded as a DW1820A, see this thread on reddit.

Are you able to figure out if the card fits the one announced in the upcoming kernels on the linux-wireless wiki?

Also, is your sound working? I seemed to be in the work too...

Please note my device is 9350 instead of 9343. 

When I tried with Ubuntu 15.04, not only the wireless isn't working, but also the graphics card, and power management had serious problems.

I can use my Android USB tethering for now. But, this ***!

What steps did you take to install 15.10 om the 9350? Having some difficulty doing a dual boot. Any insight you have would be appreciated. 

In terms of the wireless card, you should get an Intel 7265 for 30 bucks. Should get you up and running.

Yes, my card is indeed: "14e4:43a3", and I have saw the news on linux wireless that the driver is queued for kernel 4.4. 

That is a long wait. So, I am hoping someone or organization can backport the patch to current linux distros.

I know the OP asked about WiFi, but for those of you who have the 9350, have you found workarounds for power management functions like suspend/hibernate/etc. not working out of the box?

Since my 9350 is currently on the way, I am also interested in this. I could try to backport the firmware, however, I have never done that before. So if compiling goes wrong, I will probably not be able to get this error fixed. 

Anyhow, does anybody know if the firmware is compiled into the kernel? B/c I think compiling your own Kernel is a bad idea for Kernel updates will most likely break the firmware again. If it lies outside the Kernel I could try it.

No suspend hasn't worked so far. Almost everything else worked fine (sound, mic, touchscreen, trackpad, keyboard). WiFi DID NOT work out of the box, but just replace the WiFi card with the superior intel 7265.

So I appplied a Patch to the git firmware tree from 4.4 Kernel and I got the file. I do not take any responsibility if this file harms or damages your computer and I certainly do not know if this works or not. 

So, you can download the file here: http://ge.tt/9tFiZ9R2/v/0 

This files needs to be in /lib/firmware/brcm/

Rights should be -rw-rw-r--

I dont know if the Kernel needs to know about the file or anything, I am not a Kernel developer. Anyhow, happy testing.

Just to be transparent, you can acually do it yourself.

1. Clone the linux firmware archive

git clone https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git 

cd linux-firmware

2. Checkout the right commit

git checkout 66d3d8d7607c

3. Download the patch from here http://www.spinics.net/lists/linux-wireless/msg142705.html 

The desired file is now available: brcm/brcmfmac4350-pcie.bin

Copy that file to /lib/firmware/brcm/ with sudo cp brcm/brcmfmac4350-pcie.bin /lib/firmware/brcm/

Hope that helps!

Make sure you have Kernel 4.2+, like the one shipped with Ubuntu 15.10. Power management works out of box.

I have Ubuntu 15.10 installed with the latest 4.2.0-16 kernel from the standard repos. I have also tried kernel version 4.2.0-17 from wily-proposed and have tried 4.3.0-040300 (kernel.ubuntu.com/~kernel-ppa/mainline/v4.3-wily/) from ubuntu's mainline kernel builds. I have the QHD+ screen on the 9350 and it only seems to wake back up after a suspend on the 4.3.0-040300 kernel. The funny thing is that it doesn't boot that way.

When I try to use the 4.2 kernels, booting to ubuntu is fine. I am welcomed with the graphical UI and I can access ttys. But, after a suspend, my display stays off it seems. Not even the backlight is on.

When I boot to the 4.3 kernel, upon boot, I get a black screen, but I can tell the backlight is on. If I suspend the computer by shutting the lid (wait 10s), and then wake it by opening it (wait 5s), then I get a graphical UI. Every suspend works fine after that for me actually. I just have issues at boot for some reason.

Let me know if you guys experience this with your hardware on whatever you guys are running. @SKYRED, do you have a QHD+ screen or the FHD?

As for the broadcom wl driver, I had tried this weekend to install arch linux and grab the latest sources from their AUR, but with no luck to getting the card to talk to the driver. I don't think the broadcom provided wl driver itself knows to talk to the BCM4350. I mean, I can see module loaded, but no hardware tries to use it or gets linked to it. When I was trying this, I was using the latest Arch kernel (without trying to push to an unstable one) of 4.2.2 or something.

I did also see that BCM4350 support was to built into the kernel by 4.4.

I have a FHD screen. When I use Ubuntu 15.10 or Kernel 4.3rc7, the power management works for me, never ran into the problems as you said. Sorry.

Not that i can think of. Make sure the file is readable for all users, but other than that, no. So I think this has to wait until 4.4.

But thanks for trying.
