Bug 513245

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1b99) Gecko/20090605 Firefox/3.5b99 (.NET CLR 3.5.30729)

I'm unable to connect to 3G broadband using Sierra AirCard 880E via NetworkManager.


NetworkManager Identify the device and modem-manager creates a new Sierra modem
but it is unable to make a connection.

I think there's a problem with the AT commands that are being sent to the modem.
The link below points to the AT commands document from Sierra website :
http://www.sierrawireless.com/resources/documents/support/2130617_Supported_AT_Command_Reference-v2.4.pdf




Reproducible: Always

Steps to Reproduce:
1. log in
2. put sierra card in the slot
3. kde4 network manager applet notify that :
   Network Interface /dev/ttyUSB0 attached
   Connection on Sierra AirCard 880E device failed



With pppd the AirCard connects to the internet, e.g :
# pppd /dev/ttyUSB0 file /etc/ppp/peers/gsm

I'm using kde4 from the following repositories :
http://download.opensuse.org/repositories/KDE%3a/KDE4%3a/Community/openSUSE_11.1_KDE4_Factory_Desktop/

http://download.opensuse.org/repositories/KDE:/KDE4:/Factory:/Desktop/openSUSE_11.1/

http://download.opensuse.org/repositories/KDE:/KDE4:/Playground/openSUSE_11.1_KDE4_Factory_Desktop/
