Configuring UTL Dial Up Modem on Ubuntu.
Like on windows you don’t get any software package to install the UTL RUIM holder for connecting to the internet. The thing you have to do on Linux is that, at first check whether the Wvdial package is installed on your Ubuntu or not. If this package is absent download this package and install this package. Then just you have to do is following..
At first to check whether your device is detected by the system or not write this in terminal
$ ls /dev/ttyUSB*
If your result is /dev/ttyUSB0 than proceed further otherwise unplug your modem and try again or you may have to restart.
Once the modem is detected write the following command in terminal
$ gksudo gedit /etc/wvdial.conf
and than paste the following
Modem = /dev/ttyUSB0
Baud = 230400
Init1 = ATE0
#Init2 = AT$PBTYPE=1 RPTCON=1 MTRPTTYPE=3 SMSRUIM=0 SMSTYPE=1
Init3 = AT+CTA=0
Init4 = ATEOV1
Init5 = AT
Init6 = ATS0=0
ISDN = 0
Modem Type = Analog Modem
Phone = #777
Username = your firstname.lastname@example.org
Password = your number
Stupid Mode = 1
New PPPD = yes
Save the file and than close the window.
Now dial using the following command
$ sudo wvdial
Now wait for about 30 seconds and you should be surfing the net.
And remember you may have to dial 5/6 times in the terminal before you have a internet connection. Now you can enjoy the internet connection on your computer.
