unforunatley my Edimax EW-7811Un WIfi Dongle with an integrated Realtek RTL8188CUS chip is not working under my ubuntu 12.04.

After having it connected the first time it worked right away and I was able to connect to my WiFi network. However the connection was unstable and it disconnected every couple of minutes.

So I googled and found this tutorial on how to install the correct drivers: http://forum.ubuntuusers.de/topic/realtek-rtl8188ce-treiber-installieren/2/ (see the second post).

After having executed all the steps my wifi stick gets not recognized as a network device at all.

I tried this How to install driver for RTL8188CUS Wireless adaptor? which unfortunately didn't chnage the situation.

Then I tried to follow this tutorial to figure out what went wrong: My WiFi adapter is not working at all, how to troubleshoot?

The device is not shown, when I execute sudo lshw -C network.

Do you have any ideas how to get it to work?
