Ubuntu :: Cannot Apt-get, Or Wget Anything?

I'm typing this on my linux laptop, at work. My Firefox works fine, but I cannot apt-get, or wget anything. To get my Firefox to work, I just went into the Firefox preferences, checked "Automatic proxy configuration URL" and entered the url that I have. Now Firefox works fine, but the rest of my system does not.o be a similar setting in System>Preferences>Network Proxy. There is check box for "Automatic proxy configuration" and a field for a "Autoconfiguration URL". I put the same URL that put into Firefox here and told it to apply it system-wide, but my apt still does not work. This is a big deal because I need to install software and I really don't want to start manually downloading packages, plus I need ssh.

I have googled extensively on how to get apt to work from behind a proxy, but nothing seems to be working. I don't have a specific proxy server and port; rather I have some kind of autoconfiguration URL. Plus, my system has no /etc/apt.conf file at all. Any ideas on how I can get my system to be able to access the internet? It's very strange to me that Firefox can, but apt, ping, wget, etc cannot.
