modem-manager not working

[alexfish]

With your permission, I ought to join this thread.

I have a similar case, though I have a different modem. The drivers were loaded and I can connect to the internet, but it does not retain; I have to enter the same commands whenever I plug the modem. Can you please post how to load the drivers every time the modem is connected.

Thanks in advance.

Here is a sample
Remember to change the ID's according to the device Highlighted in blue , as listed by the (lsusb) command

sudo su

gedit /usr/bin/option_1C9E:9605

add code : Remember to change the ID's according to the device Highlighted in blue , as listed by the (lsusb) command

#! /bin/bash
echo 1C9E 9605 > /sys/bus/usb-serial/drivers/option1/new_id

save the file and exit gedit

chmod +x /usr/bin/option_1C9E:9605

gedit /etc/udev/rules.d/option.rules

add the code: Remember to edit the device Id's according to your device , note the lowercase letters !!!! IE , c , not C :

ATTRS{idVendor}=="1c9e", ATTRS{idProduct}=="9605", RUN+="/sbin/modprobe option"
ATTRS{idVendor}=="1c9e", ATTRS{idProduct}=="9605", RUN+="/usr/bin/option_1C9E:9605"

save and exit

if not loading try re-plugging the device

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.

the usb-devices commend gives following output:

T:  Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#=  5 Spd=480 MxCh= 0

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

so it looks like I have a driver right?

the other command gives

kris@kris-1011PX:~$ ls -al /dev/serial/by-id
totaal 0
drwxr-xr-x 2 root root 80 mei  4 21:20 .

lrwxrwxrwx 1 root root 13 mei  4 21:20 usb-Vodafone_Group__Huawei__Vodafone_Mobile_Broadband__Huawei__0-if02-port0 -> ../../ttyUSB1

lsusb gives

Bus 001 Device 005: ID 12d1:14ae Huawei Technologies Co., Ltd.

after making the option file and option.rules with 12D1 and 14AE

the usb-devices command gives

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

not sure if i386 would make any different , may only apply to modeswitch , but not sure

but can check the system build with this command

echo SYSTEM_BIT=$($(which getconf) LONG_BIT)

should see 32 or 64 , this will then suggest which sakis3g to download

coincidently , can you connect with Network Manager.

as regards sakis3g the script nearly always works its Bash , so only aspect to look at here is Chat
don't know if chat checks certain parts of the modem , or waits for certain signals ,

have posted methods of using terminal as serial port , look at resent posts regarding these devices

It seems that your modem is been detected. I think u should try to connect to the internet via the network-manager. Sakis3G still gives me segmentation fault and core dumped error messages. But the gnome network manager works fine for me. Hope that yours will be good too.

[kridybel]

echo SYSTEM_BIT=$($(which getconf) LONG_BIT)
gave 32 so the I386 should have been the right one

The strange thing is that in my network manager the usb modem has always been detected as mobile broadband modem.

The wizard opens, the modem is suggested, i make the selections for country and apn. When I try to make a connection the waiting wheel spins for a couple of minutes.

If I click on the network manager while spinning there is a small icon next to my connection name, which seems to indicate that there is a signal, but I do not get connected.

[malakar.subhendu]

May be your operator's network has some problem.
Try for a few times again. Is that working on your sons's lappy?
What's the signal quality.
Mine's also doesn't work sometimes. Replugs it and it works again.

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."

Hi,
got exactly the same Problem with the XS Stick P14 (1c9e:9605). After hours of searching for a solution, I did the following:
1) First tell networtk-manager, he should remember the PIN for the SIM-Card. This will be important for step 3!
2) Adding the following line in /etc/rc.local:

modprobe usbserial vendor=0x1c9e product=0x9605

This switches the stick from datastore-mode into the modem-mode.
3) Added a script with the following in auto-start:

#!/bin/sh
sleep 75
nmcli nm wwan on

This gets around the bug of the network-manager, which disables the mobile broadband after every restart. Don't be suprised about the 75 seconds wait. The USB-Stick takes up to 55 Seconds to initialisize after typing in the pin for the sim. Additionally the networkmanager is launched after the script started and it will need a few seconds to start itself. So adding at this point 20 seconds is safe, you might try up to 10 seconds, but that might fail. Will definitive fail, if you skipped point 1!
4) (Optional) Configure the mobile connection to connect automatically

Works so far, but fails, when unplugging the stick. I thought, I'll have to live with this, but then I was searching for something different and found this. I tried your advise which is described in post 11 and now replugging works. OK, it woks not 100% I still have to re-enable mobile broadband, by typing in

nmcli nm wwan on

but hey, I don't have to restart the whole machine anymore
