LOL… er… okay… I guess I missed that aspect of your original post! 😉
Even so, I am still at a loss to understanding your conundrum. How did you originally install 0.2.1.1? All of the LinkStation tutorials of which I am aware (these are but a sampling , , ), make use of the tarball (stable or nightly). To overcome the 0.2.1x broadcast issue, simply substitute the 0.2.3 tarball for the 0.2.1x tarball.
If you installed from some sort of package manager, then someone else will have to provide assistance — I do not use them. Surely, though, someone in the LinkStation_General mailing list can put on the correct path in the regard.
