Thread: USB modem in ubuntu

Hello everyone..

I have dual boot of windows xp and ubuntu,I am using internet through a usb modem
(reliance zte MG 880) in windows xp.How can i use this usb modem in ubuntu??

Thanks..

STEP 1: Enter the command."sudo pico /etc/wvdial.conf" (You will be asked to enter the admisnistrator password). This will open the file wvdial.conf.


or enter the following commend


sudo gedit /etc/wvdial.conf

STEP 2: Delete the complete contents and paste the following in that file.

[Modem0]
Modem = /dev/ttyUSB0
Baud = 115200
SetVolume = 0
Dial Command = ATDT
Init1 = ATZ
FlowControl = Hardware (CRTSCTS)
[Dialer cdma]
Username = 9380689709
Password = 9380689709
Phone = #777
Stupid Mode = 1
Inherits = Modem0

STEP 3: The Username and password in the above content should be your reliance net connect number

STEP 4: Now everything is set for you to connect.

For connecting go to Terminal and enter
"sudo modprobe usbserial vendor=0x19d2 product=0xfffd".
This command is for ZTE MG 880 cards only for other cards it is different. It will ask you to enter a password. Now enter your administrator password.
Then type "sudo wvdial cdma" now the following thing will appear in your Terminal.


--> WvDial: Internet dialer version 1.60
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ
ATZ

--> secondary DNS address 202.138.96.2
--> pppd: h�[06][08]h�[06][08]��[06][08]

This shows your connected to the internet.
Open your firefox browser and start browsing.

Note:
Everytime you may have to type the last two commands to connect to internet.
sudo modprobe usbserial vendor=0x19d2 product=0xfffd
sudo wvdial cdma

otherwise " wvdial cdma" is enough

Thank you...

it works in Ubuntu, but when i try this configuration in Redhat Linux , terminal shows that i am connected to internet,it also give me ipaddress,primary dns address and 2ndry dns server address but when i open firefox, it gives me error you are not connected to internet or ping to some domains like ping Yahoo!, reply that unknown host.

make sure that you are not in offline. if yes then go to file and un check work offline...

Thanks for this post. I have tried the the first statement
sudo gedit/etc/vwdial.cong on my terminal but I keep getting the message (command not found). The screen I am getting is like:

sarmad@sarmad-laptop:~$ sudo gedit/etc/vwdial.conf
sudo: gedit/etc/vwdial.conf: command not found
sarmad@sarmad-laptop:~$

Can you please help me knowing the reason why I am getting this message and my command is not executed. I am still very novice on this topic

Thanks a lot

sarmad first you need to create the file wvdial.conf

so first you need to type sudo pico /etc/wvdial.conf

then try the rest of the code in sundar ima's post.

The God Slayer: Thanks a lot for the reply. I had only a stupid mistake which was simply not leaving a space after gedit. However, it did not work with me. I have installed Ubuntu 9.x and I followed the explained method but to no avail. I am still trying, this time with the code sakis3g , but I have not yet reached any result. Any help is much appreciated

hi sarmad...
don't worry about your mistake.
to err is to human.

by the way... i googled a bit on you problem and here's what i found.
hope this works.....

Download Packages and their dependencies. The package will be for WVdial that somehow enables UBU to get online. Package file names:
wvdial_1.60.1+nmu2ubuntu1_i386.deb
libuniconf4.6_4.6-2_i386.deb
libwvstreams4.6-base_4.6-2_i386.deb
libwvstreams4.6-extras_4.6-2_i386.deb
The WVDIAL installer package requires the dependency packages listed above. So install them in the following order:
libwvstreams4.6-extras_4.6-2_i386.deb
libwvstreams4.6-base_4.6-2_i386.deb
libuniconf4.6_4.6-2_i386.deb
wvdial_1.60.1+nmu2ubuntu1_i386.deb


after you have done all these goto
nextdoornerd.blogspot.com
Search for the post titled: Making BSNL EVDO work in Ubuntu.

However you need to type sudo wvdial each time you need to get online since there is no auto detection like it happens in WIN XP.


hopefully you will get your solution there.

enjoy.

Thank you so much for taking the pain of searching on behalf of me. I have not yet applied your proposed method, but I found that a Huawei Modem can be connected rather straight forward with my Ubuntu 10.10. The usb modem I am finding difficulty in having the Ubuntu to detect it is the a Qualcomm usb modem. BTW, I downloaded the Gobi-loader found in the (Synaptic Package Manager) which is supposed to deal with Qualcomm, but it also did not work. I know that the Synaptic Package Manager is responsible for downloading and installing packages to enrich ubuntu, but I do know how to use it to download and executes the deb programs you mention in your reply; may I have your help in this? Thanks

downloading deb packages from synaptic is easy...
just write in the name, select it and then click apply.....
it will get downloaded and installed.

but if you want to download any deb package manually by google search then search and download it first then just double click it to install.
