Looks like a driver issue. I sanitized the instructions from several sources, the person I was helping reported apparent initial success with the Realtek driver built+installed manually:

1) Make sure the system is up to date and development tools are installed:
sudo apt-get update && sudo apt-get upgrade -y && sudo apt-get dist-upgrade -y
sudo apt-get install --reinstall build-essential
sudo apt-get install --reinstall linux-headers-generic
sudo apt-get install --reinstall linux-headers-`uname -r`

2) Get the appropriate driver file from realtek.com. Its name will end with .tar.gz. The model you are looking for is RTL8191SE (NOT VA2).

3) Open a terminal, go to the folder where the file was saved:

$ cd Downloads

4) Uncompress the file:
$ tar -xvzf 92ce_se_de_linux_mac80211_0005.1230.2011.tar.gz

5) Change to the directory
$cd rtl_92ce_92se_92de_linux_mac80211_0005.1230.2011

6) Build & install
    1. Change to Super User
       $ sudo -s
    2. Compile driver from the source code , install it to the kernel
       # make && make install
   3. Reboot:
       # reboot
