At the second command I got

Code: Select all

fatal: destination path 'ath10k-firmware' already exists and is not an empty directory.

Do I have to make that directory empty or delete it?
thanks

Go to the next command since you already cloned the firmware

Wi-Fi is working now
Thank you very much

Post by **JeremyB** » Sun Apr 24, 2016 12:20 pm

Great please change subject in original post to include SOLVED

EDIT: If you can't fix your Skylake issues other than downgrading the kernel, you can install backports when booted into the older kernel

Code: Select all

sudo apt-get install build-essential linux-headers-generic
wget https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v4.4.2/backports-4.4.2-1.tar.gz
tar -zxvf backports-4.4.2-1.tar.gz
cd backports-4.4.2-1
make defconfig-wifi
make
sudo make install

Reboot into the same kernel and wifi will work
