Thanks for reading, i have an HP mini 110-1030LA, it had Windows XP, tottaly functional, a little slow but funtional, i decided to install kubuntu saucy (32 bits), everythings seems to be better, the speed increased sustantialy, but it couldn't detect neither wireless nor wired networks. I decided to try (not installing) ubuntu 12.04 (32 bits) on a live usb disk, but the problem prevails.

On Ubuntu go to Software Sources, select Additional Drivers tab and if there's any driver listed for your network cards, install it.

It is common to have ubuntu configured to use a static ip on first boot.

Verify that /etc/network/interfaces is changed from this:

iface eth0 inet manual

to this:

iface eth0 inet dhcp
