Ericsson N5321 not showing

Hello,
at first I want to say that I'm new to ARCH, so please dont kill me for my Questions.

I'm using ARCH on my T440p Thinkpad, and I'm confused, because my Ericsson N5321 WWAN module doesn't show up, even when I have installed modemmanager and networkmanager.
It isn't shown in ifconfig, only my ethernet,loop,wifi is shown.
So It looks like the driver isn't loaded correctly.
I'm using the 3.15.1-1-ARCH Kernel.

In lsusb I can see this device:

Bus 003 Device 004: ID 0bdb:193e Ericsson Business Mobile Networks BV

Pls can you help me enabling this ?

Yes, it's the first result and a problem which isn't that which I've descirbed.
I can't even see this medem in Networkmanager, or even in ifconfig. I don't have problems with disconnections (till this point)

Re: Ericsson N5321 not showing

You could try the solution, even if the problem is not the same.  What is the output of "ip link"?

You could also try "sudo modprobe cdc_ncm" to start the kernel module manually.

Re: Ericsson N5321 not showing

Thanks, I didn't know the ip link command (I ever used ifconfig).

Now the device appears in my ifconfig list ({after typing ifconfig wwp0* up}

       wwp0s20u10i6: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        ether 02:15:e0:ec:01:00  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
)

But its again not showing in networkmanager
