10.04 network manager ZTE MF626i

[gregwilkins]

I've encountered a new breed of ZTE MF626 - the MF626i which Telstra Australia just started selling today, which network manager is not detecting as a modem.

If I insert the device, the kernel correctly sees the first SCSI CD and ejects it, it then see the modem (and the micro SD card in the modem):

I have purged switch mode from my system (I tried it, and it just left the original CD image mounted).


I tried following the last step on the page http://en.ubucentrum.net/2009/12/how...-modem-in.html and created the /usr/share/hal/fdi/information/20thirdparty/20-zte-mf626.fdi file.

this resulted in network-manager trying to scan the device, but
/var/log/daemon reported:

I suspect that I could probably use wvdial to make it work, but I'd really prefer not to have to delve into that.... any idea how I can make network manager detect this as a modem?

[gregwilkins]

I gave wvdial a go, and had some success with the following conf file:

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,"IP","telstra.internet"
Username = username@bigpond.com
Password = password
Phone = *99#
New PPPD = yes
Modem Type = Analog Modem
Stupid Mode = 1
CarrierCheck = No
Check DNS = 0
Auto DNS = 1
Dial Command = ATD
Modem = /dev/ttyUSB1
Baud = 9600


running wvdial got:

[506] wvdial

--> Initializing modem.

--> Disconnecting at Mon Jul 19 15:47:09 2010


Before the disconnect I was able to do ifconfig and saw:

tun0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
inet addr:10.10.0.38 P-t-P:10.10.0.37 Mask:255.255.255.255

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)


So the modem looks like it is kind of working... probably an issue with the wvdial config I wrote.... all the more reason I want network-manager to detect and handle this for me.

Hi

does this help

if NM does not pick the correct tttyUSB then opt for a method such as the wvdial , ppp you will have force the use of tty port IE in wvdial.conf : Modem = /dev/ttyUSB0 or other
a standard ZTE device uses ttyUSB2

or you could try Sakis3g

Hi Greg;

in your first post, you say

If I insert the device, the kernel correctly sees the first SCSI CD and ejects it, it then see the modem (and the micro SD card in the modem):

and the printout you gave suggested to me your device was being seen as a modem, (ttyUSB0 etc) and could thus be configured as here

.. I would have gone ahead and configured network manager from there . I suspect it would work fine

____--

the thread you quote

http://en.ubucentrum.net/2009/12/how...-modem-in.html

talks of using usb_modeswitch: I don't think you need it if the system gives you the ttyUSB0 printouts ...

did you install it? which version?

..... so I would suggest your extra steps (which you don't detail ..) are not helpful, or even causing the problem !!!!!!!!!

[gregwilkins]

PDC,

the problem is that network manager does not see the modem, so it does not create a connection using it.

I've had a little success with wvdial, but I think I'm still lacking the write wvdial.conf script. But then my preference is still to get network manager to work.

Note that I installed modeswitch 1.1.3 and it works better, but is not really any difference to not having modeswitch at all, as the eject works fine.

So in summary, I think the kernel has correctly seen the modem, but network manager is not using it.

[pdc]

Ok

I have used wvdial for a ZTE MF636 modem; (successfully): I used a GeorgeVita recommended script, so used ttyUSB2

the script I used was

[Dialer Defaults]
Modem = /dev/ttyUSB2
Modem Type = Analog Modem
ISDN = 0
Baud = 460800
Dial Attempts = 1
Username =
Password =
Init1 = ATZ
Init2 = AT&F &D2 &C1
Init3 = ATS7=60 S30=0 S0=0
Init4 = AT+CGDCONT=1,"IP","telstra.internet"
Phone = *99#
Stupid Mode = 1

I have put the telstra.internet into the script, having changed that from my own provider

these are only suggestions; I have included a screenshot that network manager uses: telstra don't seem to specify user and password, so I worry what you have is wrong;

anyway, just a suggestion you try this script;

I call it the usual way

sudo wvdial

if that doesn't work, we can suggest sakis3g

I have appended what network manager thinks the telstra settings are

[pdc]

and your issues have nothing to do with this ??

Problem solved

I got it working with NetworkManager by editing the Network Connection
- changed the Telstra (Next G) APN from telstra.internet to telstra.bigpond
- made sure that the bigpond user name & password was correct (i.e. user@bigpond.com)

I got it working with sakis3g by selecting the Custom APN function
- set APN to telstra.bigpond
- set the correct bigpond user name & password
