No Wireless on Ubuntu 15.10 with Broadcom 4350 Card

I have the New XPS13 Skylake laptop, which has DW1820A or Broadcom 4350 Wireless card.

I was following the instructions from https://askubuntu.com/a/60395/467270, I did

sudo apt-get install firmware-b43-installer

But, still no luck on getting wireless from on this device.

As part of the instruction said, I am asking a new question to post the new PCI ID:

[14e4:43a3] (rev 08)

Community, please help.

I was able to get wireless working by upgrading to version 4.4 of the kernel, as chili555 mentioned. As I'm writing, the Ubuntu team is at release candidate 8 of the 4.4 kernel.

To install the newer kernel version, first install Ubuntu (I used 15.10), then download the most recent Ubuntu build from the Ubuntu kernel PPA, move the appropriate .deb files on a USB drive to your laptop, and install them with dpkg -i *.deb.

I used v4.4-rc8-wily, but newer versions are released all the time. See these instructions for general guidance on upgrading to a newer kernel version.

After restarting, I installed the newest versions of the linux-firmware and linux-firmware-nonfree packages I could find. You can find them by searching online for 'ubuntu packages linux-firmware' and 'ubuntu packages linux-firmware-nonfree'. (I apologize for not posting direct links; apparently I need more reputation points to have more than two URLs.)
