modem-manager not working

[alexfish]

@rienesl

have you tried adding
"nmcli nm wwan on" to your script Re; the script which udev invokes when device is plugged

udev Rules are easier to remember , users have a tendency to forget about what's in rc.local

Have looked further into this Message :RE: segmentation fault ,

may be emanating from the pppd , and not chat

from old bugs reports , needed to find if certain file exists on the system
the code to find if file exist is

file="/var/run/pppd.tdb"
if [ -f "$file" ]
then
    echo "$file found."
else
    echo "$file not found."
fi

There is no pppd.tbd file in my var/run directory

Just noticed something;Vodafone K3806
last time see this device it was under : ZTE banner
#87

So not sure what looking at , Do Know some of these devices need different treatment as regards , Identifying the correct ports and the protocol associated::

suggest, Start A new thread , hopefully myself or some one with Knowlege of the devices will spot it.

only thing I can do is run through some of what the device is about and some testing to see if can get a CONNECT message ,

Just wanted to confirm that alexfish's solution works perfectly for a Capitel EVDO 3G USB modem (device id - 1c9e:9e00) (Service provider - BSNL India).

@surja: what was the result?

@surja: what was the result?

Well i can connect to the net if the 3G modem is detected after typing the suggested commands. But it does not work all the time. I hope there is a permanent solution to this soon.

I have a vodafone K3806 stick, which works on my sons windows 7 pc.

I'm still getting the segmentation error. I have downloaded the i386 version of sagis 3G for my eeepc 1011 running xubuntu 12.04.

but the ./sakis3g --interactive command still results in a segmentation fault after connect with 3G is selected

Sorry for riding along, but any help would be very much appreciated.

@kridybel

have had time to look at the device details . possible it has 2 ports which could be the modem

I:  If#= 3 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage

can look at this post
#62
There is a script for testing modem-manager , can post the results ,

@kridybel

modem-manager is not finding registration data from the device .

can try using ppp for the connection, call editor from command-line

sudo pppconfig

can try using /dev/ttyUSB0 first then try a connection using/dev/ttyUSB1
call ppp by the connection name IE :

pon <connection-name>

, if have permission problems

sudo pon <connection-name>

[kridybel]

Thanks,


I have made configuration files for USB0 (<name>) and USB1 (<name1>).

Nothing happens after the sudo pon <name> or sudo pon <name1> command.

What should happen after the sudo pon command?

thx for the support.
