Konfigurasi Wifi / wireless pada ubuntu 8.10 ibex

Pada tulisan sebelumnya, sudah dibahas tentang setting konfigurasi jaringan pada media kabel / wire. Sedang kali ini akan kami bahas tentang setting konfigurasi wifi atau wireless, tentunya pada linux ubuntu ibex 8.10.
Adapun wifi yang kami gunakan adalah Linksys WUSB54G ver.4.

$ sudo ifconfig

mengaktifkan wireless (wlan0)

$ sudo ifconfig wlan0 up

mencari sinyal wifi yang ada

$ sudo iwlist wlan0 scan
