Ubuntu 10.04 - Network Unclaimed

[Felipe Cristofalo]

I'm trying to use the 10.04 release of Ubuntu in a new PC, I run this commands: lshw -C network, ifconfig -a, nm-tool and iwconfig.
This is their results:

lo no wireless extensions.

I have no wireless cards on this PC, just that Gigabit Ethernet, so I have no internet connection.. How can I fix this?

Appreciate the help.

PS: I write this post from another computer, copying every line from the Ubuntu's Computer Terminal

Hello friend.

This version of Ubuntu is old, we are already in 13.10 with kernel 3.11, recommend that you upgrade your Ubuntu at least to version 12.04 (LTS). The Ubuntu Forums - BR's exclusive support to the Brazilian public that uses the Ubuntu distribution, in your case I recommend that you consult the International Forum of Ubuntu.

It's actually to anyone that speaks/writes in portuguese, since the entire thread is in english, I'm closing it.
