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.
