Modem Network DIsconnected. You are now offline

**apocalyptod** · November 1st, 2011

I'm a new user of linux environment. I'm using ubuntu 11.10 and a MTS Mblaze USB modem. I have installed it correctly and it was working good at first but when I restarted my system then I was unable to connect my Modem again. Whenever I click on that MTS connection, a message prompts up "Modem Network Disconnected. You are now offline." Please help to get me out of this problem.

Thanks & Regards.

"Modem Network Disconnected. You are now offline."

It was working for 11.04 and 10.10. What they have changed..?

Hi all

can have a look at
How To : Mobile Broadband Connections [ Ubuntu 11.04 : 10.10 : 10.04 : 9.10]

Take Note of:
11.04 users: First read post #59
and
TESTING MODEM-MANAGER: need to get mm-test.py :: To do the test disable all networking on the Network Manager

but follow the link To get this to work as it should can Look here : http://ubuntuforums.org/showpost.php...83&postcount=9

at post #61 there is a script for checking modems would be interested in the output from the argv "tty"

I can connect to internet using wvdial, But without networkmanager connection, I can't experience Ubuntu completely. I think the device recognized and the drivers are loaded. I tried downgrading to
network-manager_0.9.0-0ubuntu1_i386.deb, but not working.
