When i'm using my university connection I can't run
apt-get update normally as I do at home or any other place.
Everything else (that use connection) works properly.
I've already tried to change the repositories provider to a local one (Brasil) and now i'm using the official Canonical repos.
It doesn't leave 0% [waiting headers] part.
How could I debug this? What should I tracert to find where the connection is goin down?
