Mobile Broadband with Ubuntu

While I was searching for solution to get my  broadband connected to the internet using Ubuntu OS last 2 days, I can see that a lot of people were also in my shoes. So I decided to explain in details how I get to overcome this problem sucessfully.

First of all, I'm using Ubuntu 8.10 but I think this should work for whatever version of ubuntu. Bare in mind, this solution is for model E220 HSDPA modem, but I've heard some feedback that it might work on other modem too. Just give it a try.. Who knows it might work

1. Applications -----> Accessories -----> Terminal

sudo gedit /etc/wvdial.conf

Press ENTER & input your password if neccessary

2. gedit application will pop out end edit it with this

[Dialer Defaults]
Phone = *99***1#
Stupid Mode = 1
Modem = /dev/ttyUSB0
Username = user
Password = pass
ISDN = 0
New PPPD = yes
Baud = 1843200
Init2 = ATZ
Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem

Save & Close..

3. Restart

4. Applications -----> Accessories -----> Terminal

sudo wvdial

Press Enter

If u're getting this for ur last few lines, meaning that u are connected

--> Carrier detected. Starting PPP immediately.
--> Starting pppd at Fri Apr 24 09:37:23 2009
--> Pid of pppd: 7864
--> Using interface ppp0
--> local IP address 10.21.3.71
--> remote IP address 10.64.64.64
--> primary DNS address 123.136.100.2
--> secondary DNS address 123.136.100.3

5. Final step.. Open your firefox..

Press File option and uncheck 'work offline' checkbox. You can now start surfing

If you're getting this error message

--> Cannot open /dev/ttyUSB0: No such file or directory
--> Cannot open /dev/ttyUSB0: No such file or directory
--> Cannot open /dev/ttyUSB0: No such file or directory

Plug off your modem and plug in back.. wait for 10 seconds and start redialing again. Everything should works fine..
