Sore ini iseng-iseng nginstall ubuntu di HP 520. Instalasi berjalan normal. Semua driver di-detect dengan baik.
Laporan Selesai!
Masalah baru muncul waktu coba konek ke wireless network. Padahal beneran lho, itu 3945 nya ada.

Tuh, ada kan ? Tapi entah kenapa ngga mau konek. Padahal ESSID nya udah ditulis manual juga.. hiks. 
Iseng-iseng tanya paman Google, akhirnya ketemu thread ini :
Try installing the backports for Hardy.
sudo apt-get install linux-backports-modules-hardy-generic
and then restart
Siyap, boss!
Konfigurasi ulang wireless networknya dan berhasil! MAKAN-MAKAN ™
