After a fresh Sabayon installation I tried getting my UMTS-modem (Ericsson F5521gw) to work.
Sadly, I ran the installer of Arduino https://www.arduino.cc/download_handler.php?f=/ide_beta/arduino-1.9.0-beta-linux64.tar.xz which at first made the "start broadband connection" option in Gnome Network Manager vanish, then after some tinkering also the modem in the "new connection" dialog.

Anybody any idea on how to fix this? It worked like a charm before I did the fresh install. |
