Aere,

yes the NM2230 is your card then it should be fully supported.

If you like to try the old 12.04 release you can download the old cd
image from the main server:

http://cdimage.ubuntu.com/lubuntu/releases/12.04/release/

Or you can install the old kernel packages and start your new lubuntu with it:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2-precise/linux-headers-3.2.0-030200_3.2.0-030200.201201042035_all.deb

generic kernel:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2-precise/linux-image-3.2.0-030200-generic_3.2.0-030200.201201042035_i386.deb
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2-precise/linux-headers-3.2.0-030200-generic_3.2.0-030200.201201042035_i386.deb

if you need pae:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2-precise/linux-headers-3.2.0-030200-generic-pae_3.2.0-030200.201201042035_i386.deb
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2-precise/linux-image-3.2.0-030200-generic-pae_3.2.0-030200.201201042035_i386.deb

do a

sudo dpkg -i *.deb

then reboot your system using the "new" kernel. In that way you'll
discovery if is the problem is the kernel or the driver.
If something goes wrong... Simply reboot with the stock kernel then
delete the 3.2.
Let me know.
