Add the installation CD/DVD to the software sources and install the package "build-essential" from there.

[lightfile]

i think that the cd / dvd installtion is already marked up as a source. but i don't know where to find what you called "build-essential". i didn't find a place where i can install specificlly from the cd .

bare in mind that the rt2800 is blacklisted now, the results of the commands u gave me are:

Ok, try to install the package:

sudo apt-get install build-essential

and install the kernel headers by double clicking:

http://de.archive.ubuntu.com/ubuntu/...12.20_i386.deb

http://de.archive.ubuntu.com/ubuntu/...-12.20_all.deb

After that download the driver from

http://media.cdn.ubuntu-de.org/forum...repared.tar.gz

and compile it as described

[lightfile]

sudo apt-get install build-essential

Package build-essential is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'build-essential' has no installation candidate


the header kernel (which i downloaded when i was logged in windows 7) , i tried to install , nothing happened , but i can see from the system , that they are already installed.
