Without an internet connection, you will need to download several packages on another computer and transfer them on a USB key or similar. Please go here and download the following:

build-essential, libc6-dev, gcc, g++, make, dpkg-dev, linux-headers-generic and linux-headers matching your running kernel.

Find out your running kernel with:

uname -r

For example, if you get 3.5.0-19-generic, then you will need to download and install linux-headers-3.5.0-19-generic. When you have all these packages downloaded, move them to the desktop of the Ubuntu machine and install them with:

sudo dpkg -i Desktop/*.deb

The wildcard * means install all the .deb files. Be sure to download 32- or 64-bit as appropriate. At the download site, 32-bit are called i386 and 64-bit are amd64.

Now get the driver package here:

Transfer it to your desktop, too. Right-click the tar.gz and select Extract Here. Back in the terminal, do:

cd ~/Desktop/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514.2012
sudo make install
sudo modprobe rtl8723e

Let us know if you get stuck.

In this answer it is reported that you need another version for the 3.5 kernel. – gertvdijk Jan 29 '13 at 8:52
Or use the Ubuntu 13.04, that comes with working 8723 drivers (and the alx ethernet driver too). – ubfan1 Jun 22 '13 at 21:23
