I think I messed up pretty bad this time. So my wireless wasn't working and I was trying to reinstall some stuff through synaptic package manager. At this time, my wired connection to the internet still worked. Next, i marked wireless-tools for removal, and wpasupplicant for reinstallation. Then I changed my mind and marked wireless-tools for reinstallation all before I hit apply. After I hit apply, and the system did all the installing/uninstalling, I resetting my computer. When i started it up, I noticed that my system could not load a notification. It toled me that hte panel encountered a problem while loading "OAFIID: GNOME_FastUserSwitchApplet" and asks me if i want to delete the applet from the configuration. Also, my wired connection notification icon disappeared and now i have absolutely no internet connection whatsoever. If anyone could help, it'd be great.... it's been bugging me for hours.
