Hmm just a quick thing worth noting... even if you did switch to ethernet, you might want to bring the device up. If you only have one ethernet card [that means one NIC and no wifis] probably

ifconfig eth0 up

is what you are looking for. Then most likely either

pump

or

dhcpcd

should give you a connection, although it is possible the Internet is already on after just bringing the device up. Anyway post back some stuff, eventually errors and whatnot. And you do need to be root to use these commands.

[edit]

If you have more than one NICs or a wireless, if eth0 doesn't work you might want to try eth1 in the ifconfig command. Also, if that's the case run dhcpcd eth1 [dhcpcd defaults to eth0.. and you have no idea how much i swore at myself one night not knowing why my internet was not working]
