I'm running Ubuntu 14.04 on lenovo yoga 13. Previously my wireless was working correctly, but only after running a script to fix the wireless:

cd /opt/rtl8723au-master
make clean
make
sudo make install
sudo modprobe 8723au 

This no longer works though. I recently had an update for a new kernel version. After updating I can no longer use the above script to connect to wireless. The script now eventually returns: Module 8723au not found

iwconfig: lo no wireless extensions

lspci -vvnn | grep Network: Nothing is returned

uname -a: Linux "computer-name" 3.13.0-43-generic #72-Ubuntu SMP Mon Dec 8 19:35:06 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

Also I would like to note this laptop does not have an ethernet port so I cannot connect to the internet at all.

If anyone has any suggestions that would be greatly appreciated, or if you need more info from me just let me know.

I had a similar problem recently. When the kernel gets update the headers for the driver also gets update. So we need the map the correct headers. I got a script similar to yours which worked for my driver. You can try to change the driver (from rtl8188eu to rtl8723au) and check whether thats helps you. Run the code below in terminal and reboot.

Here is script what worked for my driver

sudo apt-get update
sudo apt-get install linux-headers-$(uname -r)
sudo apt-get update
sudo apt-get install build-essential
sudo apt-get install git
sudo git clone https://github.com/lwfinger/rtl8188eu
cd rtl8188eu
sudo make all
sudo make install
sudo insmod 8188eu.ko

This is your wireless device:

Bus 001 Device 005: ID obda:1724 Realtek Semiconductor Corp.

It is covered by 8723au. I suggest you try:

sudo apt-get install build-essential linux-headers-generic git
git clone https://github.com/lwfinger/rtl8723au.git
cd rtl8723au
make
sudo make install
sudo depmod -a
sudo modprobe 8723au

When Update Manager installs a later kernel version, recompile after the required reboot:

cd ~/rtl8723au
make clean
make
sudo make install
sudo depmod -a
sudo modprobe 8723au
