Untuk bisa konek internet menggunakan modem di ubuntu. Terlebih dahulu kita install wvdial agar modem terbaca. Masuk terminal:
Applications->Accessories->Terminal
thesenu@thesenu:~$ sudo apt-get install wvdial
Masukkan password kemudian tunggu sampai selesai.
Setelah itu kita cek konfigurasi wvdial, dengan:
thesenu@thesenu:~$ sudo wvdialconf

Found a modem on /dev/ttyUSB3.
Modem configuration written to /etc/wvdial.conf.
ttyUSB3: Speed 9600; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"
ttyUSB4: Speed 9600; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"
ttyUSB5: Speed 9600; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"
ttyUSB6: Speed 9600; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"
Kemudian merubah settingnya
thesenu@thesenu:~$ sudo nano /etc/wvdial.conf
Lalu akan keluar seperti berikut:
[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
ISDN = 0
New PPPD = yes
Connection = your APN
Phone = *99#
Modem = /dev/ttyUSB4
Username = your username
Password = your password
Baud = 9600
Stupid Mode = 1
setelah itu keluar CTRL+X dan simpan Y.
Jalankan wvdial dengan
thesenu@thesenu:~$ sudo wvdial
akan keluar:

Apabila sudah mendapatkan IP maka sudah bisa konek internet
