Ubuntu on Lenovo Yoga 3 Pro

I have the same ultrabook and I managed to fix mine with the above suggestion. I first ran:

sudo modprobe -r ideapad_laptop

Then I created a blacklist with:

sudo nano /etc/modprobe.d/myownblacklist.conf

Added the following line:

blacklist ideapad_laptop

Rebooted and Wifi working fine from then on. I'm running Ubuntu 14.10 Gnome 3 Edition and works pretty well. Hope this helps

I have my yoga 3 on WiFi with ubuntu 14.10. Make sure you check the option to install third party drivers during installation. You also need to make sure that the ideapad_laptop kernel module is not loaded, add a line "blacklist ideapad_laptop" to /etc/modprobe.d/blacklist.conf and reboot.

I started a HOWTO for installing Linux on the Lenovo Yoga 3 Pro

While the information. The ideapad_laptop module has been fixed and does no longer disable Wifi and Bluetooth on the Yoga 3. Meaning it is completely sufficient to install the Broadcom drivers with the latest Ubuntu 14.10 Kernel.
