Internet Connections Ubuntu 12.04 Server with Unity GUI

view story

http://askubuntu.com – I am very new to all this and thought I'd have a look at ubuntu with the hope of it running my server. I have installed Ubuntu 12.04 Server which went fine, I then installed Unity again this was all fine. I can access the GUI fine but my one problem is Internet Connection. It works fine, I can access the internet and everything but I can't view System Setting>Network as it says 'The system network service are not compatible with this version' I also can't see any network connections or if I click on edit connections it opens fine but I can't actually edit or add anything as it is all shade (HowTos)
