Problem with Wireless Adapter on IGN2010 at Lenovo 3000v100

Setiap kali merestart Wireless Adapter di Lenovo 3000v100, muncul pesan kesalahan :
Menghidupkan antarmuka wlan0:
RTNETLINK answers: No such file or directory

Menderteminasi informasi IP untuk wlan0...
RTNETLINK answers: No such file or directory

gagal.

Kalau diamati dengan system-config-network, jenis wireless adapternya adalah :
Intel Corporation PRO/Wireless 3945ABG[Golan] Network Conenction (wlan0)

Atau jika dengan perintah baris lainnya :

Belum ada tanda-tanda Wireless Adapter dapat diaaktifkan. Sedang mencari tahu langkah-langkah penyelesainnya. Dikenal namun tidak bisa diaktifkan. Mungkin driver Intel PRO/Wireless 3945ABG belum ada atau belum cocok. Bagaimana mengecek keberadaan dan kecocokan driver ya?

Coba download driver
