Found this excellent post that solved all my "no-name" wireless adapter installation woes.
I used the v3.4.4 (2012/11/12) driver on Mint 14.
I got one error during installation:
ERROR: Module 8192cu does not exist in /proc/modules
and changed Step 5 to use pluma instead of gedit
sudo pluma /etc/modprobe.d/blacklist.conf
In case the original post ever disappears here are the essential bits:
Download the Realtek RTL8191SU drivers from here
Navigate to the downloaded folder and install the drivers with:
sudo bash install.sh
Blacklist the original drivers with:
sudo pluma /etc/modprobe.d/blacklist.conf
Go to the end of the file and add the line: blacklist rtl8192cu
Reboot
