This is quite a fundamental bug, if you can edit network connections through Connection Editor, unless you revert to the command line your computer is pretty useless. Whilst some of us know how to do this via the command line, if we want Linux to be adopted by average users then the community need to ensure that these sort of bugs do not make it through to the final release otherwise new users will look elsewhere.
