I've recently purchased a Lenovo Yoga 13 and put Ubuntu 13.04 on it last night. I was unable to get wireless to come on and thought that I would mess around with it today. Today I have followed the detailed 'how-to' at: http://majordamo.wordpress.com/2013/05/15/getting-the-realtek-rtl8723ae-bt-wi-fi-card-to-work-on-a-lenovo-yoga-13-on-linux-mint-13-ubuntu-12-10/ The problem is I can not download and install the required headers as I do not have ANY internet connection on this device. Is there any way for me to get them on a flash drive and bring them to the Lenovo?

Any and all help is appreciated. Thanks

Update: as of 14.10 utopic, these steps are no longer needed (the driver was added to the staging tree of the 3.15 kernel. If you still need to build the driver from source, I believe the code in the kernel should be used rather than the lwfinger branch.

That how-to link is outdated; the latest version of the rtl8723au wireless driver can be found at https://github.com/lwfinger/rtl8723au.

Here are the steps to install:

git clone https://github.com/lwfinger/rtl8723au.git
cd rtl8723au/
sudo make install
sudo modprobe 8723au

When you update the kernel, you'll need to run these steps again to get wireless working (except for the git clone). To fetch the latest version of the code, use git pull.

The bluetooth driver for that chip can then be found at https://github.com/lwfinger/rtl8723au_bt and installed like this:

git clone https://github.com/lwfinger/rtl8723au_bt.git
cd rtl8723au_bt/
sudo make install

It has to be said that you need to make sure that you modprobe exactly as it says here. I kept doing sudo modprobe rtl8723ae, which turns out wasn't the right one. –  Hosh Sadiq Nov 5 '13 at 21:50
My wifi runs a little slow but it works and so far the best answer I've found. Thanks. +1 –  Kirill Fuchs Nov 9 '13 at 17:27
ATTENTION: The bluetooth driver caused a kernel panic for me during (recovery) boot (kernel 3.13.0-24generic on ubuntu gnome 14.04). To fix it merge github.com/lwfinger/rtl8723au_bt/pull/9 in. –  GameScripting Apr 26 at 20:38
The driver shipped with 14.10 doesn't work for me, connection to wifi-router lasts for minutes and finally fails. lwfinger-driver was doing well, until the upgrade to 14.10. When i try to fall back to lwfinger-driver built and installed from sources, i fail at "sudo modprobe 8723au" step. Device is busy. It looks rather that the stock driver from ubuntu is taking control before lwfinger-driver. Anyone figured out how to cope with it? –  vak Nov 1 at 12:52
OK. got wifi working with this: $ cat /etc/modprobe.d/blacklist-ideapad_laptop.conf blacklist ideapad_laptop @david you may want add this to your update info. –  vak Nov 1 at 13:03

The author merged in DKMS support a few months ago, but didn't integrate it into the make install process. Following these commands will add it to DKMS so you don't have to manually recompile after every kernel update.

From https://github.com/lwfinger/rtl8723au/blob/master/README.dkms:

To get DKMS to work:

  • Install dkms
  • Copy this source to the directory /usr/src/8723au-0.1/
  • Run (as root):

    dkms add -m 8723au -v 0.1
  • Test a build:

    dkms build -m 8723au -v 0.1

From now on this driver should be available for any new kernels.

Post #6 here, although it is for a different driver, describes the process to download and install linux-headers and build-essential on a flash drive, transfer them to the Yoga and install them. http://ubuntuforums.org/showthread.php?t=2050126 It is cumbersome and tedious, but it can be done.
