MAKING IT PERMANENT
If this driver works with your hardware, you will want to have it available every time you boot up.
Save the driver tarball to your /root directory, which is persistent if you use a pupfile.
Add the uncompress and depmod commands to /root/.etc/rc.d/rc.local

cd /
tar -zxvf /root/rtl8180-sa2400-0.21.tar.gz
depmod

This will install the driver every time you boot up, ready to load and configure as explained above.
A script for this purpose, "rtl8180-sa2400-connect" is available.  Just modify the script to include your wireless settings.
