>> pastikan dulu file2 dibawah ini udah ter-install di-sypnatic:


- firmware-b43-installer

- b43-fwcutter



>> dan pastikan juga paket2 dibawah ini udah diremove juga dari sypnatic:


- bcmwl-kernel-source.

- bcmwl modaliases


>> cari dikolom pencarian n kalo udah direstart dulu..
driver gak usah diinstallin lagi, bawaan dari ubuntu juga udah ada.. restart

seharusnya gak perlu banyak gitu, cukup network controller aja. itu dibagian akhir sendiri liat hasil dari lspci -v ente:

Network Controller..

kernel driver in use: wl
kernel modules: brcm80211

>> seharusnya kernel driver itu ngambil driver dari kernel modules-nya. seharusnya kalo kernel driver: wl, berarti kudu ada modules yg wl juga. begitu juga sebaliknya. berhubung disitu kernel modules-nya cuma "brcm80211", yaa kudu pakai yg itu aja. coba dulu hasil dari:

lsmod | grep wl

lsmod | grep brcm80211

sudo -i

modprobe -rf wl

modprobe brcm80211

lsmod | grep brcm80211

iwconfig
