I tried to install connman and it didn't work, so I removed it. Then I tried to sudo apt-get install network-manager network-manager-gnome` and that obviously didn't work so I found the correct .deb packages and installed them. Ethernet now works, but wireless doesn't. Did I do something wrong? Whenever I press my hardware wireless switch it doesn't react. The applet tells me that wireless is disabled by a hardware switch, but my only hardware switch doesn't do anything.
