Konfigure wifi atheros menggunakan madwifi setelah upgrade kernel

Hi blog, kali ini aku ingin mengupdate tulisanku sebeumnya yang mengenai wifi di acer aspire 4520. Sebenarnya tidak banyak si yang harus di update, tapi supaya lengkap, hasil output dari kompile sourcenya, aku sertakan juga.

Hari ini, setelah aku selesai mengupdate fedora 9, aku restart fedoraku. setelah masuk kembali ke fedora, ternyata wifiku tak kedetek. Oh no, kok ga kedetek yah .... Setelah kucek lagi, sepertinya kernel terbaru di fedora ku ini tidak memanggil madwifi yang ada di kernel terdahulu. Karena paket instaler yang lama masi ada, jadi ga perlu lagi donwload.

saat ini kernel yang kugunakan adalah

[root@rito ~]# uname -a
Linux rito 2.6.27.12-78.2.8.fc9.i686 #1 SMP Mon Jan 19 20:14:35 EST 2009 i686 athlon i386 GNU/Linux

Sebenarnya , ada keinginan juga siy untuk install kernel dari source langsung. Cuman yang jadi masalah kalau kompile kernel yang ada itu adalah, banyaknya modul yang harus kita pilih. Nah, berhubung fedora udah menyediakan updatenya, jadi mending download aja, menggunakan perintah yum update. lalu reboot fedoranya, dan kernel terbaru pun terpasang sudah.

OK, kita langsung ke langkah-langkahnya.
Seperti yang udah saya utarakan di atas, karena paket yang lama sudah saya ekstrak, maka saya tidak perlu lagi untuk mengekstrak ulang. Jadi cukup masuk ke direktornya saja

[root@rito rito]# cd madwifi-hal-0.10.5.6-r3875-20081105
[root@rito madwifi-hal-0.10.5.6-r3875-20081105]#

setelah masuk ke dalam direktory tersebut. kompile kembali sourcenya

[root@rito madwifi-hal-0.10.5.6-r3875-20081105]# make

berikut adalah proses kompilenya

Checking requirements... ok.
Checking kernel configuration... ok.

OK, sampai tahap ini, module madwifi telah masuk ke dalam kernel. kita cek kembali di /etc/modprobe.d, apakah sudah ada madwifinya

root@rito madwifi-hal-0.10.5.6-r3875-20081105]# more /etc/modprobe.d/madwifi
alias wifi0 ath_pci
alias ath0 ath_pci
options ath_pci autocreate=sta

Ah .. sudah ada rupanya. sekarang reboot laptopku.

Setelah muncul lagi di windows, cek menggunakan iwconfig

[root@rito ~]# iwconfig
