Instalasi driver wifi Broadcom di Ubuntu

Setiap rilis Ubuntu penulis tidak pernah absen menggunakan metode ini di laptop yang memakai wifi broadcom, sejak Ubuntu Jaunty, Karmic Koala sampai Lucid Lynx yang sekarang sudah rilis. Untuk versi Karmic Koala dan Lucid Lynx mungkin sudah membawa beberapa paket sendiri di CD Installer Ubuntu-nya. Beberapa laptop mungkin sudah otomatis ter-install setelah selesai proses installasi Ubuntu, tapi tidak untuk laptop penulis.
Sebelum memulai instalasi paket-paket driver untuk wifi broadcom, pastikan cek terlebih dahulu di terminal dengan mengetik perintah lspci, nanti akan keluar beberapa informasi tentang hardware yang Anda gunakan. Tampilan di komputer penulis seperti berikut:

$ lspci | grep Network
05:01.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)

Download beberapa paket di bawah ini disini.

1. ndiswrapper-utils-1.9_1.54-2ubuntu1_i386.deb
2. ndiswrapper-common_1.54-2ubuntu1_all.deb
3. b43-fwcutter-011.tar.gz
4. broadcom-wl-4.150.10.5.tar.gz
5. broadcom-win-32.tar.gz

Untuk memudahkan proses instalasi ektrak paket 3,4, 5 dan tempatkan semua paket-paket tadi di home direktori Anda (gambar WF.1). Buka terminal, lalu ketik perintah di bawah ini.

$ sudo dpkg -i ndiswrapper-common_1.54-2ubuntu1_all.deb && sudo dpkg -i ndiswrapper-utils-1.9_1.54-2ubuntu1_i386.deb

Proses akan seperti tampak di bawah ini.

$ sudo dpkg -i ndiswrapper-common_1.54-2ubuntu1_all.deb && sudo dpkg -i ndiswrapper-utils-1.9_1.54-2ubuntu1_i386.deb 
Selecting previously deselected package ndiswrapper-common.

Kemudian gunakan ndiswrapper untuk meng-install driver broadcom (broadcom-win-32.tar.gz/ driver dari Windows Xp) dengan mengetik perintah berikut:

$ sudo ndiswrapper -i bcmwl5.inf
installing bcmwl5 ...

$ sudo ndiswrapper -l

$ sudo ndiswrapper -ma
module configuration information is stored in /etc/modprobe.d/ ndiswrapper

$ sudo ndiswrapper -mi

Selanjutnya masuk ke direktori b43-fwcutter-011, install b43-fwcutter-011 tersebut degan perintah-perintah di bawah ini:

$ sudo make
make: Nothing to be done for `all'.

$ sudo make install
install -d -o 0 -g 0 -m 755 /usr/local/bin/ 
install -o 0 -g 0 -m 755 b43-fwcutter /usr/local/bin/ 
install -d -o 0 -g 0 -m 755 /usr/local/man/man1/ 
install -o 0 -g 0 -m 644 b43-fwcutter.1 /usr/local/man/man1/ 
Pindah ke direktori broadcom-wl-4.150.10.5/driver. Selanjutnya meng-install firmware broadcom:

Sampai tahap ini proses instalasi selesai, silahkan Anda coba koneksi wifi Anda. Jika tidak bisa cobalah logoff dulu atau dalam beberapa kasus laptop harus di-restart untuk mengaktifkan perubahan. Gambar WF.2 memperlihatkan proses wireless sedang mencari koneksi.
