Note: This article will help you to “Dial” your USB CDMA modem with Network Manager in Ubuntu, Assuming it’s already working fine with wvdial. If you are modem is not detected or working by wvdial, then it’s problem with Modem Detection in Ubuntu, if this is the case, then this solution is not for you.

Update: If you are on Ubuntu 10.04 LTS (Lycid Lynx) Beta – 1, please test ModemManager [1] and submit your response here [2], your feedback would help us to push this package to final build.

Since Ubuntu 9.10 release lot of people has complained about NetworkManager + Reliance NetConnect Broadband+ (Huawei EC1260) is not  working out of the box, which was working fine with Ubuntu 9.04. This was happening due to bug in modem manager. I have just now uploaded patched version of modem manager which has solved the problem. So, No more gnome-ppp or wvdial, Here we GO:

Step – 1:

Get access of CLI and please make sure that Ubuntu 9.10 with uninterrupted Internet and make it up-to-date with latest udpates to be at safer side.

#sudo apt-get update

#sudo apt-get upgrade

Step – 2:

Please add my PPA to get patched version of Modem Manager. From here [1] you can find the detail about patched version of Modem Manager

#sudo add-apt-repository ppa:hardik-dalwadi/ppa

+++ Snapshot From Live System +++

+++ END +++

Step – 3:

Now, check the current version of your Modem Manager (FYI).  And again update the system to get header of patched Modem Manager from my PPA.

#dpkg -l | grep modemmanager

#sudo apg-get update

+++ Snapshot From Live System +++

person@CANONICAL-DESK:~$ dpkg -l | grep modemmanager
ii  modemmanager                             0.2.git.20091014t233208.16f3e00-0ubuntu1        D-Bus service for managing modems
person@CANONICAL-DESK:~$

+++ END +++

Step – 4:

Now install Modem Manager from my PPA which is higher patched version from current version, after successful installation reboot the system.

#sudo apt-get install modemmanager

#sudo reboot

Step – 5:

Now after successful reboot, You should get the New CDMA Broadband option under Network Manager. I am assuming you have already inserted Reliance NetConnect Broadband+ Modem, if not please do that.Please follow the Images for more information on How to connect in GUI Mode.

Note: We have also tested with Tata Photon+ service with Huwei EC 1260 and Haier  CE100 Modem. It’s working out of box. Please also test modems from BSNL / TATA / Reliance  with NetworkManger  and let us know in comment, whether it’s working or not.  Your help would be much appreciated.

Please select New Connection, since Reliance NetConnect Broadband+ requires Mobile Number as Username / Password, You have to enter it manually. In case o Tata Photon+, You can select it from list.

I think it’s BUG with NM, it has not ask for Username  / Password in manual selection of provider, we have to edit it again. It may not be the case in your scenario. So in my case i am editing settings again.

Since Network Manager is giving prirority to WiFi / Ethernet connect, you have to disconnect them to swithc over to your Reliance NetConnect Broadband+ Connection.
