ive found this to be a problem for every new-bie and thought of to share with u guys.Actually i’m using ubuntu 7.04 at present.this post doesnt assume that your Linux distro recognises your modem.
So first connect your modem and start off with lsusb and see the output if you see there your mobile’s manufacture name.
then execute “sudo wvdialconf”This tries to detect the baud rate of your modem and writes it to /etc/wvdial.conf
and also you have to make some manual changes to wvdial.conf,like update the username and password options…so execute the command sudo gedit /etc/wvdial.conf if you are using Gnome
or sudo kate /etc/wvdial.conf if you are using KDE
our wvdial.conf should look like
Modem = /dev/ttyUSB1
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
stupid mode = 1
Modem Type = Analog Modem
Phone = *99#
ISDN = 0
Username = a
Password = b
Baud = 460800
now if ur using ubuntu then voila ur done with …..coz it automatically updates DNS server in resolv.conf.If u use any other distro open file:/etc/resolv.conf and enter following setting service named start
and save it…..
thats it u are done with…..just type wvdial and ur connected to net…….just type ctrl+c to disconnect……or type Killall pppd to kill all active connections……
Some common problems 1. Internet connected successfully but page is not opening
fire up following command
and enter this
nameserver 220.127.116.11 nameserver 18.104.22.168
Now u will be able to open web page without any problem.
2 when ever i try to connect internet i get this error (Device or Resource busy)
This is the common problem with dialup connection via dial up.
1. remove usb cable from the port and reinsert it. If that not help than.
2. run following command
it will remap ur usb port to ttyACMO1or 2
Life is much better in ubuntu. ubuntu automatically update the dns server detail in resolv.conf whenever user dial dialup connection. and ubuntu automatically update the wvdial.conf file with dialup/phone setting whenever user fireup this command
but on other distro user have to enter following command to update wvdial.conf file
