Malem agan2 sekalian.
Ane mau tanya, kan ane ceritanya mau nembak hotspot kampus pake wajan bolik. Buat server ane pake ubuntu server 12.04 d komputer ane, soalnya ntar mau ane bagi2 lagi buat anek2 kostan.
Berdasarkan artiket http://linuxplained.com/linux-compat...adapters-2012/ada beberapa usb wifi yg katanya suport d ubuntu 12.04. Akhirnya ane beli deh salah satunya : TP-Link TL-WN722N
Tanpa babibu ane colokin buat ngetes langsung apa bener bisa ga? buat hidupin wirelessnya "sudo ifconfig wlan0 up".
Alhasil setelah di cek "ifconfig" :

eth0 Link encap:Ethernet HWaddr 00:11:2f:b2:11:23

dapet tuh ada interface wlan0
Cek lagi "sudo iwconfig" :

lo no wireless extensions.

eth0 no wireless extensions.

Nsh yg ane ingin tanyakan, dari data diatas apakah wireless usb ane dah work gan? Soalnya ane tes coba pake koneksi add-hoc dr laptop temen ane, waktu ane scan "iwlist wlan0 scan" malah katanya

wlan0 No scan results

Gitu aja gan, mohon pencerahanya
