Q: Failing to install driver for wireless pci card I installed a wireless PCI adapter (Edimax N300) and it was working right away albeit not very good. In my quest to improve perfomance I made a mistake and followed this 
guide (under 6): RealTek Wireless adapter issues. (RTL8192ce and RTL8192cu)
basically installing the wrong driver for "cu" instead of "ce". After the reboot the card was not detected (at least I got no indication of any wireless connections around and there were plenty before). Since then I failed trying to install several drivers to get the card runnning again. 
I download the respective archives and then do:
sudo apt-get install build-essential
makes
sudo make install

I get an error at the "make"-stage which reads as follows (apologies for the German):

Can anybody help?

A: Allright, I managed. Here is what I did: Open terminal, type "gksudo nautilus", go to folder "etc/modprobe.d" and opened "blacklist-native-rtl8192". Then I put a "##" in front of every line (so that they are not processed).
