The driver for your Intel Centrino Wireless-N 2230 is already installed in Ubuntu 12.10. If it is not working as expected, either the wireless switch is off; check:

rfkill list all

Or it actually is working and the driver can't or won't do 802.11N speeds; disable it temporarily to see:

sudo modprobe -r iwlwifi
sudo modprobe iwlwifi 11n_disable=1

If that helps, we'll write a conf file to make it persistent:

gksudo gedit /etc/modprobe.d/iwlwifi.conf

Add a single line:

options iwlwifi 11n_disable=1

Proofread, save and close gedit. If it is none of these, run and post:

dmesg | grep iwl
