USB internet Data card modem on Linux

USB internet Data card modem on Linux

Here is procedure for connecting USB interent Data card on Linux box.

I have tested it on Reliance,Tata and BSNL card on linux.

1)Connect USB Data card on USB port of computer

2) Open a terminal window.

3) Log in as root, i.e. type “su -” sans the quotes and enter the root password.

4) "wvdialconf /etc/wvdial.conf" It will create a wvdial.conf file in etc directory (Please remove quote ).

5) Then use to edit the file “/etc/wvdial.conf”.(you can use any editor I would recommend gedit. Command would be “gedit /etc/wvdial.conf”).

6) Enter/edit the following text into this file.

[Modem0]

Modem=/dev/ttyUSB0

Baud=115200

SetVolume=0

Dial Command = ATDT

init1=ATZ

init2=AT+CRM=1

FlowControl= Hardware (CRTSCTS)

[Dialer Reliance]

Username= username

Password= password

Phone= #777

Stupid Mode= 1

Inherits = Modem0

7)Disable network connection of your computer

8) Final step is giving the command “wvdial Reliance”, and if everything is proper you should be able to connect to the internet.

For Tata: username and password is “internet” without quote

For Relianace : username and password is phone number of the device

For BSNL modem: its username and password is “cdma”

I used only three USB modem till this time but I hope it will work for all the USB modem.

Please let me know if you get any problem in your connection.

Do comment if you like it.

BSNL EVDO Internet data card

BSNL EVDO Internet data card speed Upto 2MBPS

Back one year BSNL Launched 3G technology internet data card for giving 2 mbps internet connection on wireless technology, that too in only in INR 500. They launched this service long back but they start selling it just few days back.

I am using this internet data card since one month and I got really amazing speed on this data card. At-least in India this is the fastest and most stable connection till this time that I have used. I used TATA,Reliance and Airtel internet data card but neither of those were stable nor good speed.

I got its maximum speed till 1.2 mbps in good condition. Speed varies from location to location. At my room I get average speed 512kbps, maximum speed goes to 1.2mbps and most of the time speed varies betweeb 500 kbps to 700kbps. At my office I get average 250kbps speed nad maximum speed till 800kbps It varies between 250 to 400kbps.

Good things about BSNL Data card.

1) Up to 2 mbps speed.

2) Documentation only as much as you need to get a fixed line phone.

3) Available on rent.

4) Only in INR 500 you get unlimited internet connection with a good speed.

Bad things About BSNL data card

1) Roaming is not there with it till this time. (As per official nce they got infrastructure over entire country they will make it roaming.)

2) On wireless so sometime problem occurs (not reliable as fixed line but more reliable than other provider in India).

Its usage is very simple.

Just Install->change the user name password->connect

Yes it’s like this only it works with windows XP as well as windows Vista also. For Vista they will give you an aditional patch.I have not tested it on Linux or Mac but I am sure it would work because it just need a dialler and in Linux and Mac you can use wvdial for dialling internet connection (on Linux I have tested Tata and Reliance USB internet data card, will post that soon here) I will test it and I will share the result.

One thing that you need to remember if they haven’t told you username and password you will be in trouble. You may not get it on any website or forum. Its username and password both is CDMA.I got the same problem after taking the connection and I found solution after reaching to their office only. On web I found use phone number and It was bullshit reliance user might have thrown a guess with that answer.
