When you ran the ifconfig eth0 did it give your ethernet card an ip address? I know it will be time intensive, since you can't copy and paste, but if you could give us a snippet of your first few lines of ifconfig eth0. Also, have you tried pinging any address. At the shell type ping www.getlinuxonline.com. Does that get you anything? If not, try pinging an ip address, such as 18.104.22.168 (yahoo's ip, or one of them anyways). See if that does anything.
