with m7 I had a nice network icon in my system tray - showing that I was connected to a wired network (which also showed in sysinfo as ‘online’)
when I did a clean install of m8 this went and there was a different little network icon that wasn’t able to show any info (and showed in sysinfo as ‘not able to tell if online’)
updating from m8 to rc1 and there is no network icon at all in the system tray bit
