I am seeing this issue on my Dell XPS 13 as well. Everything works fine with WPA & WPA2 personal at home. I just can't connect to WPA2-Enterprise at work.

I have tried this "https:/ /launchpad. net/~diane- trout/+ archive/ wpasupplicant- gnutls" PPA, but it doesn't help. Also I have disabled the IPv6 to "ignore".

And I keep getting this from my syslog file:
