No wireless Ubuntu 15.10 for Lenovo Yoga 3 11

Question

I got a Lenovo Yoga 3 11 and installed Ubuntu 15.10 trouble is

no wifi
no ethernet (computer is too thin)

I've heard this is a very specific bug. After some reading I have a Qualcomm Atheros Device but forget the exact number. Other questions address the Broadcom case.

After downloading the CD image, I installed a dual boot partition with Windows 10 and Lenovo has the wireless driver for Windows.

Writing this question from my phone will continue to supply more details.

I have no idea what these do or if they are correct

One possible hardware solution is usb ethernet adaptor but guess what? No internet no cd rom so i can't download http://www.asix.com.tw/products.php?op=pItemdetail&PItemID=86;71;101&PLine=71

dpkg -l | grep "linux-firmware"

Please [edit] your question and add output of lspci -knn | grep Net -A2; rfkill list terminal command. — Pilot6, Jan 21 '16 at 13:05
You can enable wifi by using the first two commands from my answer. Everything else will be much easier with an internet connection. — Pilot6, Jan 21 '16 at 13:37
Why do you complain about no cd-rom? You can always copy files using a flash drive. — Pilot6, Jan 21 '16 at 15:16
I suspect the driver lacks the needed firmware. Let's find out which it wants and I will propose a solution involving a flash drive. Please run: dmesg | grep ath and post which firmware file it is looking for but not finding. It may be Direct firmware load for ath10k/QCA6174/hw2.1/board.bin failed with error -2 or some such, but we need to know the exact details. — chili555, Jan 21 '16 at 15:41
@chili555 please take a look. Indeed its looking for something and not finding it. Not sure — john mangual, Jan 21 '16 at 16:13
So chili555's answer worked? That's good, but it is not clear why. — Pilot6, Jan 21 '16 at 20:01

Your wireless driver requires firmware that is not installed by default. Please download this file on some other computer and transfer it with a flash drive or similar: http://archive.ubuntu.com/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.149.3_all.deb

Transfer it to the Ubuntu computer and drag and drop it to the desktop. Now, on the Ubuntu computer, open a terminal and do:

cd ~/Desktop
sudo dpkg -i linux*.deb

After it is done, please do:

sudo modprobe -r ath10k_pci
sudo modprobe ath10k_pci

Your wireless should be working but it might take a reboot.

I am afraid this will not help. By default Ubuntu 15.10 contains 1.149.2 firmware that contains the same files related to ath10k as 1.149.3. – Pilot6 Jan 21 '16 at 16:35
+1. But I have no idea why this worked. – Pilot6 Jan 21 '16 at 20:03
Glad it's working by whatever means! – chili555 Jan 21 '16 at 20:12

The wireless adapter is probably blocked by the platform driver.

You can fix it by running

sudo modprobe -r ideapad_laptop
sudo rfkill unblock all

This should unblock it until a reboot.

To make it permanent you can run

sudo tee /etc/modprobe.d/blacklist-ideapad.conf <<< "blacklist ideapad_laptop"

This will permanently disable the platform driver.

A better solution is to report a bug to launchpad by running:

ubuntu-bug linux

and add there output of

sudo dmidecode | grep "System Information" -A8

If you drop a link to the bug report, I will be able to take care of it.

The issue has been fixed upstream, but it needs to be backported to the current Ubuntu kernels.

I can't report a bug without Internet. What do you mean "upstream"? The most recent 15.10 kernel I can find dates to October – john mangual Jan 21 '16 at 13:28
I mean that in kernel 4.4 it is fixed. Just run the first two commands. That should be fixed. – Pilot6 Jan 21 '16 at 13:35
I noticed blacklists for ath-pci and bcm43 but not ideapad_laptop are those relevant? – john mangual Jan 21 '16 at 13:59
No internet still – john mangual Jan 21 '16 at 14:03
