Well thanks for all the help, folks!
After all I reinstalled OSX from scrap and copied all the important stuff over from the backup. I did this twice as I figured out that installing Avira Antivirus would immediatly causing the Internet connection to die. No luck with uninstalling this software, I had to reinstall everything.
Good luck this AV-software runs on my other iMac (27" mid-2012) without hassle.

****! Sometime after reinstalling the machine and upgrading to Mavericks I got stuck again with slow Internet speed. Can´t figure it out what to do or where to start over.
So if reinstalling the iMac does not help and it is fot sure no hardware problem, what would you suggest to do?
