I have Novatel MC760 CDMA modem.

I plug it in ubuntu 14.04 and have to wait 60-120 seconds and after that Network Manager lists that device if I click icon or type in terminal

$ nmcli dev
DEVICE     TYPE              STATE        
ttyUSB0    cdma              disconnected 
wlan0      802-11-wireless   connected    
eth0       802-3-ethernet    unmanaged

I see network connection that I called CDMA

I can connect to it almost instantly.

In terminal I type 

nmcli con up id "CDMA"

and it works.

I can disconnect with

nmcli con down id "CDMA"

But I can't connect again by typing nmcli con up id "CDMA"

I have to unplug and plug and wait 60-120 seconds for device get listed in nmcli dev

Any ideas how to get it working after disconnection without manually re-pluging and waiting?

Try wvdial. It prints more verbose information.

  • Yes. wvdial works and I can re-connect now. I will wait a bit more for other answers as wvdial is not 100% smooth. I would like Network Manager to handle all networking in one place without opened terminal windows. – Artem Mar 05 '15 at 10:56
