I am currently unable to connect to the Internet on my newly upgraded Ubuntu 14.04. Network Manager is able to identify wireless networks, and it can detect when I'm plugged into an Ethernet connection, but it always seems to timeout when trying to connect. I've tried this both at work and at home and get the same results.
Here is a link to the output of dmesg

Here are some diagnostics:

I feel like I have tried everything and am running out of options. Please let me know if anyone has any idea what to do from here.
Thanks so much!
