Hello James,

Ok, I'll try describe a process here to get this modem running.

First, the thread you point to could make it work with a ppp connection.
That is not the way to do it though, since it has a much more efficient way to do communication.
Here is a alternative howto:

1. Patch your kernel with this patch:

2. After reboot with this new kernel, you should see like:


[   20.122239] cdc_acm 5-8:1.1: usb_probe_interface
[   20.122243] cdc_acm 5-8:1.1: usb_probe_interface - got id
[   20.122322] cdc_acm 5-8:1.1: ttyACM0: USB ACM device
[   20.124354] cdc_acm 5-8:1.3: usb_probe_interface
[   20.124357] cdc_acm 5-8:1.3: usb_probe_interface - got id
[   20.124438] cdc_acm 5-8:1.3: ttyACM1: USB ACM device
[   20.127392] cdc_acm 5-8:1.9: usb_probe_interface
[   20.127395] cdc_acm 5-8:1.9: usb_probe_interface - got id
[   20.127481] cdc_acm 5-8:1.9: ttyACM2: USB ACM device
[   20.134318] usbcore: registered new interface driver cdc_acm
[ 20.134322] drivers/usb/class/cdc-acm.c: v0.26:USB Abstract Control Model driver for USB modems and ISDN adapters
[   20.271221] usbcore: registered new interface driver cdc_ether
[   20.310117] mbm 5-8:1.7: usb_probe_interface
[   20.310121] mbm 5-8:1.7: usb_probe_interface - got id
[   20.329548] mbm 5-8:1.7: status ep7in, 8 bytes period 7
[ 20.329740] mb0: register 'mbm' at usb-0000:00:1d.7-8, MBM Mobile WAN Device, 02:80:37:ec:02:00
[   20.329754] usbcore: registered new interface driver mbm

You should also see a interface mb0 when you do ifconfig for example.

3. You can now test this manually, I mean without NetworkManager. Just to see that the driver part is ok.

3.1 Open /dev/ttyACM[0,1 or 2] in your favorite terminal emulator, this will give you an interface to do AT commands in.

3.2 You need a AT sequence like this to bring up your modem:
3.2.1 AT&F
3.2.2 AT+CFUN=1
3.2.3 AT*EIAC=1
3.2.4 AT*EIAPSW=1,1,"<your APN here>"
3.2.5 AT*ENAP=1,1

3.3 Now the connection should be up and you use dhclient to get an IP on mb0 like "dhclient mb0" or similar.

3.4 Time to start surf and read mails! :-)

4. To get NM to use this module, you currently need to work with the sources of NetworkManager and modemmanager. This is so far work in progress and I'm not sure when the distributions will pick these things up.

Best regards,

I just recently upgraded to the Lenovo W500 laptop which has a built-in
Ericsson F2507g WAN card.  Unfortunately I can't get this new card to
work with NM because it needs to be turned on first.  There is a thread
about how to do this manually on Ubuntu:

My sim card doesn't require a password like the newer ones so this
should be pretty simple.  But I can't seem to make it work.  I'm using
the Ubuntu NM PPA.  Any ideas?
