Ok great in the scripts folder type
ls -l
and then
cat usbmodem.sh
Then give the output of the 2 commands, don't add them to the file
hope this is what you want
roy@roy-desktop ~/scripts $ ls -l
total 4
-rwxr-xr-x 1 roy roy 106 Dec 30 10:24 usbmodem.sh
roy@roy-desktop ~/scripts $ cat usbmodem.sh
#!/bin/bash
modprobe -v option
echo "1bbb 022c ff" > /sys/bus/usb-serial/drivers/option1/new_id
roy@roy-desktop ~/scripts $

Looks good
Now reboot laptop then insert the modem and then run from the scripts folder in the terminal
sudo ./usbmodem.sh
Remember the .(dot) and reply back with the results.
roy@roy-desktop ~/scripts $ sudo ./usbmodem.sh

once again I just get Network Settings & Network Connections but it doesn't open any further to
display the option to connect to MTN

Sorry my bad forgot the -c option, download the file again and place in the scripts and remove the one that you downloaded earlier.

ok will do but I tried this before I read your post
changed the sim card settings to auto from WCDMA on my laptop through the MTN manager
settings, I rebooted my desktop with linux & tried again as before.

connected but with a green light only and similar strength to the old modem and unable
to stay connected, have to re-connect after a few minutes constantly.
I have the same problem with the old modem even with the sim card set to WCDMA, I still
only get a green light

So it connected this time around? Green is only GPRS/EDGE if I remember correctly.
hi again, sorry for the delay
yes it did connect but I tried several times and it never connects when it's in
WCDMA and that is the primary reason I bought a new modem because my old
modem had the same green light and bad signal issues (just as this one does)
although it does work great in my windows laptop when I change to WCDMA but it
won't even connect in Linux.
If I change the setting from WCDMA to Automatic the new modem will run in my
linux but it's only green (edge) and the same on the Windows laptop which really
doesn't solve any problems as that's why I changed the modem in the first place.
The Window laptop is next to my Linux desktop so It's not a poor reception issue
otherwise it wold effect both the same.
Unfortunately there is no way to change the settings without the MTN Manager which
is a Windows application I think and doesn't load in Linux .
edit..Thinking about it now it would appear as though Linux or specifically Mint doesn't
recognize WCDMA but it does see the modem, don't know if that's possible.
Here is the results that you asked for
roy@roy-desktop ~/scripts $ ls -l
total 4
-rwxr-xr-x 1 roy roy 116 Dec 30 12:51 usbmodem.sh
roy@roy-desktop ~/scripts $ cat usbmodem.sh

What is the make of the modem?

I'm sure you have, but I'm just asking anyways, have you tried different USB ports?

Since the first time you got it working did you get a green light or another colour?
I have had a blue light on occasions, usually flashing until it changes to a solid blue light and
stays on very briefly, and then changes to a flashing green until it connects to
a solid green.
If this sounds stupid please forgive me.
I do not know how the signal is processed from tower to modem to pc etc but
somehow there must be an acknowledgement that a signal has been detected and
then it is processed (does this happen via the CPU). I am thinking that could it maybe
a CPU problem or something similar. The tower is about 1 or 2 Km from me and I can actually
see it from my house and if it was a problem from the tower it would effect my Windows pc
signal. I an reluctant to try changing my distro as I think that it a bit drastic,and if it is a CPU
issue that will solve nothing, I am grasping at straws here as this only occurs in WCDMA.

Hi again
I just remember I should have said that the old modem works fine with WCDMA
in my linux machine but only picks up a green signal (Edge) even though WCDMA
is supposed to be 3G only
ok, I think it's time for us to give it a rest until the New Year as I won't be
available tomorrow and I'm sure you have lots to do also. Will re-connect with
you next year
So for now thanks a million
all the best for the New Year
Cheers

Shot no probs
Hi DWPTA
Happy New Year and hope it's a good one.
Positive developments here, I will give you a brief run down.
After spending half the night thinking about it I decided to remove everything connected to
the desktop, clean it and set up about ½ metre away, the same place where the laptop works.
Left everything off except keyboard, mouse & screen, connected the modem direct to the pc…….BINGO!!!!!!
It would appear that the usb hub is faulty and there is a signal problem when my desktop is in it's
original position as when I tried the modem in the pc at first it was in it's original position and it
made no difference, I cannot understand that as it's been there for about 5 years trouble free, so maybe I also have intermittent faults on the ports too.
I will leave it out for now and monitor it and try various set ups.
I can get WCDMA (3G only) and Automatic (2G or lower) successfully though if I need to change it for any reason I have to do it on the Windows machine, but no issue really!
#Edit….additional issues are with my Network.
3g but constantly dropping signal (flashing red) searching network, then (flashing blue) for ages
before connecting, sometimes no connection for hours and when there is it's never more than one bar…….weird because I can connect with my laptop also with only one bar but stable???
Need someone to check this tower, the signal is very unstable or I must consider another package
with another provider. I will try to get them out first
………………………………………………………………………...
In order to connect I used the original settings as before:-
roy@roy-desktop ~ $ su (enter)
Password: …………….
roy-desktop roy # modprobe -v option (enter)
insmod /lib/modules/3.16.0-41-generic/kernel/drivers/usb/serial/usbserial.ko
insmod /lib/modules/3.16.0-41-generic/kernel/drivers/usb/serial/usb_wwan.ko
insmod /lib/modules/3.16.0-41-generic/kernel/drivers/usb/serial/option.ko
roy-desktop roy # echo "1bbb 022c ff" > /sys/bus/usb-serial/drivers/option1/new_id (enter)
roy-desktop roy #
and also
~/scripts $ ./usbmodem.sh
Password:…………….
And that works too.
I have to enter whichever code each time I reboot, is there a permanent solution to avoid that
I didn't do anything else for fear of making a mistake and I need to just confirm with you again.
Also now when I check with the Modem Manager GUI I get an error when I try to request
*141# the error says:-
………………………………………………………………………………………..
Error sending USSD
GDBus.Error
rg.freedesktop.ModemManager1.Error.Core.Cancelled: USSD
terminated by network
………………………………………………………………………………………..
Hope you don't mind assisting but after all the issues prior I will understand if you wish to opt out.
I need to thank MyBroadband, Ginggs & yourself for your persistence and willingness to assist to a
sucessful conclusion, I could not have done this without you guys.
I have learnt quite a lot and I hope with all the hits others have too.
Once again thanks
Snowy
