GSM Modem Settings Set with wvdial

In this article I assume you are using ubuntu linux as operating system and Indosat M2 as a GSM card for your modem.

The first thing to do is make sure wvdial program installed in your computer. Wvdial is an intelligent PPP dialer, which means that the faster the modem and start the PPP in order to connect to the Internet. This is something like a chat program, except that use heuristics to guess how to dial and log into your server rather than forcing you to write a login script.

1.  To ensure wvdial installed (run the following command in the console)

Code:

ediant@ediant:~$ su
password :
root@ediant:~$ dpkg -l | grep wvdial

      to install the program wvdial

Code:

root@ediant:~# apt-get install wvdial

2.  The process of setting

     a. To initialize the modem

Code:

root@ediant:~# wvdialconf

Output Code:

Editing `/etc/wvdial.conf'.

Found a modem on /dev/ttyUSB0.
Modem configuration written to /etc/wvdial.conf.
ttyUSB0: Speed 9600; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"
ttyUSB2: Speed 9600; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"

     b. Edit file wvdial.conf di /etc/wvdial.conf

Code:

root@ediant:~# nano /etc/wvdial.conf

Output Code:

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Baud = 9600
New PPPD = yes
Modem = /dev/ttyUSB0
ISDN = 0
; Phone = 
; Password = 
; Username = 

      Changed to be like this

Code:

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,"IP","indosatm2"
Baud = 9600
New PPPD = yes
Modem = /dev/ttyUSB0
ISDN = 0
Phone = *99#
Password = your password
Username = your username
Stupid Mode = 1

      press CTRL + X

      press Y ( Enter )

3.   Run to connect internet
