I used to not be able to connect with my wired connection on Ubuntu 13.04. It worked magically sometimes and I clicked around in the settings. Now it's working consistently. I remember playing around with VPN but I didn't change any major settings. As I want to install another system now, I want to know what it is in order to figure out, what to do in the future. As I boot into Linux Mint on a USB I'm having the same problem, there I have not been able to figure out what to do in order to get it working.
I'm connecting to a dorm network. Other people living here seem to have no problem connecting with their windows machines. Also there are no torrent files/connections working. I see connecting peers for some files, but it doesn't start seeding.
I hugely appreciate any help. Thanks in advance!
The commands were run on the consistently working machine on Ubuntu 13.04 on a Thinkpad x230i.
