ZTE USB Modem Help

[viking777]

I decided that I wanted to try out 3 Mobile for mobile internet instead of the Vodafone connection I am using at present as they appear to have better coverage where I live. The modem they supplied my is a ZTE MF622. I thought that I would be able to make it work in the same manner as the Huawei modem I have used up till now, but it doesn't seem to be so easy, the problem is this.

If I plug in the device and perform a cold boot, the device is listed as ID 19d2:0001. If I modprobe this it creates the necessary device nodes and behaves as a proper modem should (at least for a while). However if I perform anything other than a cold boot the device is listed as ID 19d2:2000 and no amount of modprobing that will make any difference, it never creates the necessary device nodes. The problem is further complicted by the fact that if the modem fails to connect for any reason and I have to unplug it the ID changes back to 19d2:2000 and the whole thing becomes useless.

Does anyone know how I can deal with this?

3 mobile give you 3 days to return the modem if you are not satisfied with it which gives me until Monday to get it working or take it back for a refund, so I don't have long to sort this out.

Needless to say the whole thing works perfectly in my wife's windows computer so the modem is not faulty and the connection it gives from her machine appears to be very good, so I would like to get it going if I could, but having to do cold boots every time I mess around with it is not exactly convenient.

Incidentally, the modem comes with a driver cd for a mac. Is there any way I could get that to run on Kubuntu? (I think I can guess the answer!).

I can't find anything to confirm whether this ZTE modem works with linux, at least in an easy to do way.

However, don't despair. Three can supply a Huwee E220 USB dongle and this definitely works with Linux and works easily thanks to Vodafone's generous contribution of OSS to the community.

for information on settings to use with Three's network.

I've tried the setup and it works.

Hope this helps

Hi,

I've managed to botch a method to get my ZTE MF622 working within ubuntu. Its on the UK 3G network. Only problem is you loose USB based storage device functionality I still havn't found a way to get them working along with the modem! If your still wanting to give it a go let me know and I'll dig up my txt files.

Okay scrap the problems, Here is how to do if for people out there (none of this is my doing really, I've just played around with the information out there)

First you need to set up the ZTE MF622 as a modem rather than a usb drive. This is done by inserting the following script.

ACTION!="add", GOTO="ZTE_End"

# Is this the ZeroCD device?
SUBSYSTEM=="usb", SYSFS{idProduct}=="2000",
SYSFS{idVendor}=="19d2", GOTO="ZTE_ZeroCD"

# Is this the actual modem?
SUBSYSTEM=="usb", SYSFS{idProduct}=="0001",
SYSFS{idVendor}=="19d2", GOTO="ZTE_Modem"

LABEL="ZTE_ZeroCD"
# This is the ZeroCD part of the card, remove
# the usb_storage kernel module so
# it does not get treated like a storage device
RUN+="/usr/src/usb_modeswitch-0.9.2/usb_modeswitch -d 1 -v 0x19d2 -p 0x2000 -V 0x19d2 -P 0x0001"

LABEL="ZTE_Modem"
# This is the Modem part of the card, let's
# load usbserial with the correct vendor
# and product ID's so we get our usb serial devices
RUN+="/sbin/modprobe usbserial vendor=0x19d2 product=0x0001",
# Make users belonging to the dialout group
# able to use the usb serial devices.
MODE="660", GROUP="dialout"

LABEL="ZTE_End"



Make this in gedit and save it in etc/udev/rules.d and make sure the file name ends in .rules e.g. sudo gedit /etc/udev/rules.d/ZTEMF622.rules


Now you need to set up the dialing mechanism. This is done using wvdial, what you need to do is create the following wvdial.conf file if you are using the ZTE in England with Three

[Dialer Defaults]

Init2 = ATZ

Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0

Stupid Mode = 1

Modem Type = Analog Modem

ISDN = 0

Phone = *99#

Modem = /dev/ttyUSB0

Username = user

Dial Command = ATDT

Password = pass

Baud = 460800

That file is saved in etc/wvdial.conf. So you put in the terminal sudo gedit /etc/wvdial.conf then paste the dialer defaults code into that and save.

Then reboot with the modem plugged in form the begging of the reboot. Activate the modem by typing sudo wvdial in the terminal. If all is well you should be on the internet. Note: if the modem light is red then it's not going to work you need to unplug it plug it back in. It should then go green. You will need to reboot in order to get it working again.

Hope that helps

Hi - I've been trying to get my zte mf622 working all weekend. No success yet. I've copied the instructions exactly but everytime I reboot the 3 modem icon is there on the dektop and the USB drive is mounted. If When I try "sudo wvdial" I get:



satellite@satellite-laptop:~$ sudo wvdial
--> WvDial: Internet dialer version 1.60
--> Cannot open /dev/ttyUSB0: No such file or directory
--> Cannot open /dev/ttyUSB0: No such file or directory
--> Cannot open /dev/ttyUSB0: No such file or directory
satellite@satellite-laptop:~$

Any suggestions?

Problem solved - a reboot didn't work for me. I had to shut down and then bootup again (don't know how this would make a difference).

For anybody in Ireland add in the line

Init5 = AT+CGDCONT=1,"IP","3ireland.ie"

after init3 in the instructions above - otherwise everything is the same.

Thanks for this thread and JimmyI in particular. My minutes old ZTE-MF622 is now connected and running well under Debian on an Eee.

Using the same process above but with the small addition of adding the wvdial package.

Sadly the coverage where I am is 'so so'. Its good to know it is usable though for when I am on the move again.

Thanks again

which was followed by the note that a cold reboot did the trick.

However, no amount of restarting and (un)plugging devices works for me, and I get exactly the same message (only it says version 1.56 because... well, I don't have internet so I cannot update my system decently). It seems that I'm stuck by my ignorance.

So: any suggestions where I go wrong? It's a standard 7.10 gutsy, updated until Xmas 2007. A complication seemed to be that I put the USB modem in a hub, not directly into the PC, so it kept power during shutdown. However, directly pluggin it in the pc's usb ports didn't make a difference.

All the best & thanks in advance,
M.

Hello there...

I am trying to put my MF622 working, but I think gnome doesn't let use the ppp0 interface to access the internet :S

I've done the dial scripts for my area and ISP. In terminal, I run the usbmodeswitch, then gcom and finally wvdial...

In the terminal, after running these commands, it appears that I've been connected to the internet. It says my IP and other stuff...


I run the network tools app, and there it is the ppp0 with all its information... But when I get to firefox, it simply doesn't work...

What can I do??

Best Regards,
David Serrano
