Apt-get update not connecting, sources.list not fixing problem

http://www.linuxquestions.org – Hi, I'm running Kali 1.0.3 amd64 from hard drive(I know, not really Debian but was hoping someone could help). It's a new install, and I ran into an issue where the network manager said my wired network "device not ready", so I changed the [ifupdown] to true and rebooted. Ifconfig is showing me that I am sending/receiving packets and am issued an IP address (would post output but I'm not currently willing to retype everything-on a different machine). Can't check if internet works because I removed iceweasel while trying to install firefox, which is where I came across the issue at (HowTos)
