Operating System (OS) : Ubuntu
1] Plug-in modem Smartfren ZTE AC682 Buka Terminal untuk menjalankan beberapa perintah untuk mengetahui apakah modem ZTE AC682 dikenali oleh operating system
riv@riv-Aspire-5000:~$ lsusb
Bus 003 Device 002: ID 062a:0000 Creative Labs Optical mouse
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 002: ID 19d2:ffde ONDA Communication S.p.A.
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
terlihat vendor id (19d2) dan product id (ffde) modem ZTE AC682. Product id ffde berarti modem sebagai sebuah media penyimpan atau CD-ROM bukan sebagai modem.
2] eject CD-ROM dengan menjalankan perintah
riv@riv-Aspire-5000:~$ sudo eject /dev/sr*
*) untuk melihat nya gunakan perintah
riv@riv-Aspire-5000:~$ dmesg|grep cd

terlihat di sini Uniform CD-ROM driver Revision:3.20 berada pada 1
(secara umum: kalau ada CD-ROM Drive sr1, jikalau tidak ada CD-ROM Drive sr0)
maka jalankan perintah:
riv@riv-Aspire-5000:~$ sudo eject /dev/sr1
ketik password
tunggu sampai prompt muncul di terminal, ini memerlukan waktu yg cukup lama.
Catatan: software USB mode switch tidak diperlukan untuk modem ini.
3] Jalankan perintah lsusb untuk meyakinkan apakah product id diubah dari ffde menjadi ffdd.
riv@riv-Aspire-5000:~$ lsusb
Bus 003 Device 002: ID 062a:0000 Creative Labs Optical mouse
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 003: ID 19d2:ffdd ONDA Communication S.p.A.
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Catatan: jika product id tidak berubah, cabut modem ZTE AC682 dan pasang kembali serta jalankan perintah diatas lagi.
4] Berikan parameter pada kernel untuk mengenal modem dengan perintah
riv@riv-Aspire-5000:~$ sudo modprobe usbserial vendor=0x19d2 product=0xffdd
ketik password
Modem Smartfren AC682 saat tulisan ini dibuat,TIDAK dapat digunakan dengan Network Manager, karena dikenali sebagai New Mobile broadband (GSM) Connection, padahal modem EVDO Rev.A
di Nautilus terdeteksi sebagai Modem CDMA EVDO Rev.A
Apabila wvdial belum terinstall, silakan lihat tulisan lain tentang "install wvdial offline".
5] Jalankan perintah wvdialconf
Untuk merubah file, /etc/wvdial.conf sebagai basis dari modem ZTE AC682 dikenali oleh kernel.
riv@riv-Aspire-5000:~$ sudo wvdialconf
ketik password

6] edit file /etc/wvdial.conf dengan mengetikan "$ sudo gedit /etc/wvdial.conf" untuk edit nomor telepon, user name dan password sesuai dengan ISP yg digunakan.
riv@riv-Aspire-5000:~$ sudo gedit /etc/wvdial.conf
ketik password
isi semula:

ISDN = 0
; Username =
Init1 = ATZ
; Password =

Baud = 9600
Edit menjadi (copy paste saja isi di bawah ini)

Save & Quit dari gedit, sehingga kembali ke Terminal.
7] untuk terhubung ke internet jalankan perintah "sudo wvdial smart"
riv@riv-Aspire-5000:~$ sudo wvdial smart
ketik password
8] untuk mengakhiri koneksi modem, tekan Ctrl+C di terminal
