Hi! I have a 3g modem: ZTE MF710M 21,6mb/s. My linux OS (Xubuntu 14.10 x86) is not detecting my modem, only as storage and i dont' have a Mobile Broadband Connection option in Network Menu, but i can connect as Ethernet. In my modem manual it doesn't say it supports Linux, only Windows and Mac. What i have tried from what i found from internet:
I have added in /etc/usb_modeswitch.d/

Code: Select all

# ZTE MF 710M
DefaultVendor=  0x19d2
DefaultProduct= 0x1405
TargetVendor=   0x19d2
TargetProduct=  0x1405
MessageContent="55534243123456780000000000000011062000000000000100000000000000"
NeedResponse=0

I have added in /lib/udev/rules.d/40-usb_modeswitch.rules a rule with my modem vendor and id,
I have tried with modprobe, sakis3g.

usb_modeswitch doesn't contain vendor and id of modem in /usr/share/usb_modeswitch/configPack.tar.gz

And i can't find no information about this model on internet.
Can someone help me with this specific modem?

[skweek]

Not sure if this is helpful but have you seen this? http://blogger.ziesemer.com/2008/10/all ... buntu.html

The modem is in communication mode already as the "lsusb" output shows. The product ID 0x1405 is a target ID - look at config file "19d2:1225" ...

It has most likely switched automatically if you have the usb-modeswitch package installed on your system. Don't try to switch it again!

[Broli]

I saw the config file "19d2:1225" , but i wasn't sure it works for my modem because it doesn't say its for zte mf710m.
I understand it has already switched to communication mode, but why i can't see the "Mobile Connection" in Network.
And if i try to manually crate connection it doesn't see the device (it says "any device") and after i create the connection it doesn't show in Network menu. And it doesn't create a /dev/tty symlink. How to manually create it?

Sorry, no modem was detected!  Is it in use by another program?
Did you configure it properly with setserial?

Please read the FAQ at http://alumnit.ca/wiki/?WvDial

[LOM]

MF710M is not a dial-up modem, it doesn't have any serial interfaces so there wont be any serial tty devices created in your system and vwdial can not manage the dongle.
MF710M is a direct ethernet device for which you have to load the cdc_ether driver and
it will appear in NetworkManager as an ethernet device.
