I'm trying to connect to the internet via Sierra Wireless 313u mobile Boradband card (AT&T) using NetworkManager. I know there has been a lot negative press about this software, but Sierra Wireless recommends using it, so I figure it's my best shot.The problem I am having is that I am getting an error that "the IP configuation is unavailable" I have the correct device (It automatically chooses /dev//ttyUSB3), and usb_modeswitch doesn't seem to be needed:
Code:

I tried using the i switch to specify each interface, but it does not appear to be doing anything.

Here's the tail of dmesg:

Any ideas? I'm running amd64, mostly stable system, latest stable KDE.

Thanks!

Sierra mobile broadband modems do not pose as USB serial devices.
Code:
[   93.638034] sierra_net 2-1.2:1.7 wwan0: register 'sierra_net' at usb-0000:00:1d.0-1.2, Sierra Wireless USB-to-WWAN Modem, 2e:49:4c:fe:01:07
[   93.667366] systemd-udevd[3075]: renamed network interface wwan0 to wwp0s29u1u2i7
Your device is wwan0, which is then renamed by udev to wwp0s29u1u2i7 (careful, the name will change when you plug it into a different USB port). You should be able to run dhcpcd on that interface.

Depending on the device's chipset and your kernel configuration, you may also see /dev/ttyACM* devices, these can be used by networkmanager/modemmanager directly.

dhcpcd times out and no devices named ttyACM in /dev..... have I missed something? Perhaps a kernel module or something?
