Ubuntu – Ubuntu 14.04 – Connection is there but no internet access – messed resolvconf

Let me start with a disclaimer: I have tried to fix my problem by reading similar questions & answers, but so far no luck. Not only that, but I think that by making some changes to resolvconf I have messed it up further. I need someone to take me by the hand and help me fix this issue, I would be immensely grateful!

The situation is this: I am living in a building where the internet is provided by the university's network. Recently, some upgrades where done to the network, after which all my connectivity issues arose.

My Windows desktop PC will connect properly when using the same connection, no issues there. MY 14.04 ubuntu laptop, however, shows a normal connection to my router (wired or wirelessly, both work) but I am then unable to browse to any webpage.

Symptoms:
– Can ping IP addresses but not websites (DNS issues?)
– I can ssh to a server that I know is based at the university, so on the same network, and through there, I can use firefox to browse.

In case those are helpful, I will post below the output of ifconfig, and the contents of /etc/resolv.conf, which I think needs to be completely reconfigured after my failed attempts.

ifconfig:
