I've got a new Dell Latitude e7440, and a Dell Wireless 5570 HSPA+ mobile broadband card. I cannot get the broadband card to work.

I can see the card:

# lshw
  ....
  *-network DISABLED
       description: Ethernet interface
       physical id: 1
       logical name: wwan0
       serial: 46:51:4c:75:9d:ad
       capabilities: ethernet physical
       configuration: broadcast=yes driver=cdc_mbim driverversion=22-Aug-2005 firmware=CDC MBIM link=no multicast=yes

And I can get rid of the DISABLED text:

# ifconfig wwan0 up
# ifconfig wwan0
wwan0     Link encap:Ethernet  HWaddr 46:51:4c:75:9d:ad

# lshw

  *-network
       description: Ethernet interface
       physical id: 3
       logical name: wwan0
       serial: 46:51:4c:75:9d:ad
       capabilities: ethernet physical
       configuration: broadcast=yes driver=cdc_mbim driverversion=22-Aug-2005 firmware=CDC MBIM link=yes multicast=yes

But I cannot use the card in any way.

  • There's no /dev/ttyUSBx to which I could input AT commands.
  • I cannot see a mobile broadband connection in the Network manager.
  • tools like mbim-network simply say the connection to the modem failed

My Dell BIOS version is A10, and from BIOS I can see the card. It's enabled and from that perspective there shouldn't be anything wrong with it. If I need to debug the driver, I'm willing to give that a try but I need some pointers on where to start. Any help is much appreciated.

Below is a list of debug output. Please ask for more in the comments if you think of anything that's helpful.

Here's my Linux version. I'm running a modified kernel due to a multiheading docking station problem, but this modem issue occurs identically on the 3.13 kernel which was the default when I installed Ubuntu 14.04.

# uname -a
Linux slartibartfast 3.15.0-rc8+ #5 SMP Mon Jul 21 14:18:58 EEST 2014 x86_64 x86_64 x86_64 GNU/Linux

Using libqmi and qmicli, I get some interaction with the modem, but still some fairly confusing error messages. I have not yet had time to look into this further.

I can also set my PIN code with qmcli:

# qmicli --dms-uim-verify-pin=PIN,xxxx -d /dev/cdc-wdm0
[/dev/cdc-wdm0] PIN verified successfully

And get some information:

Regarding @aleksander's question in the comments of his answer, here's the error when using the apn:

  • See my answer here to understand what's happening here. As Aleksander states below, you're missing half the interface. If your using an ISP, you need to authenticate with them.

Dell branded Sierra Wireless modems, like the 5570 (bought one myself now) need a magic "DMS Set FCC Auth" command to recover from low-power mode, better explained here: https://sigquit.wordpress.com/2015/02/09/dell-branded-sierra-wireless-3g4g-modem-not-online/

If you're using ModemManager, you can try to compile your one libqmi and ModemManager from git to get this fixed.

    Just released libqmi 1.12.4 and ModemManager 1.4.4 with these fixes; time to poke your distro to get them integrated :)

You're lacking the APN in the --wds-start-network option. You wouldn't need it if you were in a CDMA/EVDO network, but it is (usually) required an explicit one in GSM/UMTS/LTE.

Once QMI WDS Start Network returns with no error, just try to run dhclient in the WWAN interface.

  • I've tried it with my providers apn, which is internet. Produces the same error. The card works fine in my phone with both no APN and the APN I just mentioned above. I'll give it a new try and post some more comments.

  • Yeah confirming that I'm getting the same error as before, even after first setting my pin code and then attempting to start the network.

    Commented Nov 18, 2014 at 21:25
  • Is it really the "generic-no-service" call end reason, even when you use the APN?

  • I've edited the exact error message to the question now, at the end. It is the generic-no-service.
