rtl8192cu driver for EDIMAX USB WiFi dongle

Since ages there is a problem with the EDIMAX EW-7811Un and it is still not solved in Fedora 20. However, the driver from Realtek should work but it is quite challenging to compile it with current kernel versions.
Here is what you have to do to get it work with kernel 3.13:

• Download the driver from Realtek.
• Download the script.
• As root run patch_rtl8188C_8192C_usb_linux_v4.0.2_9000.20130911.sh

The driver seems to have some problems still but it is way better then before. At least the connection losses are gone.

If you have any problems please let me know and I will try to fix them. Unfortunately I was only able to test the driver on my Fedora 20 system. So any results from other systems are more then welcome.
