Solution for How to Setup BSNL EvDO Internet Connection in Network Manager on Ubuntu 9.10 *Exclusive*
What was the actual Problem!!
I had been searching on GOOGLE about "How to setup EvDO AC8700" but no-where found solution for this...The same matter was with other wireless terminals.
EvDO is a device developed by ZTE corporation to provide high speed data connectivity using CDMA 2000 technology. It is also known as 3G of CDMA. We had problem after the release of Karmic Koala. But we were having no problem with Ubuntu 9.04 Jaunty Jackalope.
THE EXCLUSIVE SOLUTION IS HERE
EXCLUSIVE!!! because no one could found the solution for this Problem. Large number of EvDO users are compromising with many OS services by using wvdial alternative. I found the solution for EvDO on Karmic Koala in the end of January. This solution might work for other wireless devices too like 3G data card dongles too as I haven't tried on others, so I can't say about others. But since the reason behind the problem is same, so there is high probability that it might work for others too.
Reason was that our EvDO hardware is identified as "Qualcomm" by Ubuntu. But Ubuntu 9.10 Karmic Koala was detecting as "CONDA s.a.p Communication"
You can check by yourself (for ZTE EvDO AC8700 device only) by firing this command in Ubuntu:-
$ lsusb # will list the USB devices connected
Since it is detecting the device wrong, it is talking with device wrongly i.e EvDO listen ATR command only, but it was sending CMIE command (shown by log viewer) which was not understandable for device, result "Disconnected--you are offline" message.
--> Then I tried Live CD of Ubuntu 9.10 Karmic and check by entering command "lsusb" and . Surprisingly, it detected correctly as "Qualcomm". and then setup the connection as before and was not surprised when it connected rightly.
--> Then I did fresh installation of Ubuntu 9.10 and when it finished, I had to reconfigure it after reboot.
--> I reconfigured it and voila !! it worked...yes it worked
This made EvDO to work in Ubuntu without need of wvdial package. It is now working in Network Manager means that Network Connection can be setup in Network Manager.
I don't know actually what is the bug inside, that prevent any "lib" file to copy from CD into system during installation. But when I configured while running Live CD(i suppose) that lib or config file copied as it was in running state.
Now you will not have problem with IM client like Empathy, pidgin, etc and gwibber like clients who check connection from Network Manager. In wvdial method, Network Manager is bypassed due to which clients do not work..
Well this will work for all EvDO AC8700 users. So, enjoy Ubuntu........
THANKS for reading this HUB, and PLEASE DO COMMENT ON THIS...I am WAITING....
