Hi

which software have you installed

also need some info

open up the terminal from Applications, enter the following command

Code:

usb-devices

locate the lines indicating the device and post only those lines

the devices should also be listed in the DIR /usb_modeswitch.d

post the results of

Code:

cat /etc/usb_modeswitch.d/19d2:2000

thanks again for your prompt reply and your help

Hi

looking at the info the device has configured, but does not list as the 3520

according to information in the device_reference data base the 3520 is ZTE

################################################## ######
# ZTE K3520-Z
#
# Contributor: Paul McDermott

;DefaultVendor= 0x19d2
;DefaultProduct= 0x2000

are you sure it says 3520 on the device

will the device configure with the network manager, if not need to see if modem-manager is installed

Code:

which modem-manager

also post the results of

Code:

ls -al /dev/serial/by-id/usb*


If the modem-manager is not installed then no path to MM will show , if so you will have to install

if modem-manager is installed , will have to look further

[munshi]

thanks again for your help. and yes i am sure i have the huawei k3520 vodafone mobile connect usb stick. and the results for the commands you asked for are


which modem-manager

/usr/sbin/modem-manager


and the results for ls -al /dev/serial/by-id/usb*

lrwxrwxrwx 1 root root 13 2010-11-12 09:04 /dev/serial/by-id/usb-ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ_HUAWEI_Mobile_ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ ÿÿÿ-if00-port0 -> ../../ttyUSB0

just a small note the network manager does see a vodafone default 1 connection but is unable to connect.

[alexfish]

Hi

Are you sure the correct details have been entered in the Network Manager
PIN CODE or and PUK code
APN, username and password if required , phone number : check with service provider

is it a requirement the device to be first registered in windows,if so does it work in windows

if you are convinced all details are correct the will need further

Need to find if the device is communicating,and info from the device

START
Open up a first terminal , enter these codes

Codes:

sudo killall modem-manager

tr -s "\n" < /dev/ttyUSB0

this will monitor the replies of the device,leave this terminal open

Open up a second terminal, enter the following codes, note any responses from the first terminal

Codes:
echo -e "AT\r" > /dev/ttyUSB0

echo -e "ATZ\r" > /dev/ttyUSB0

if there is no response IE "OK"then I would assume there could be a fault with the device, unplug the device and reconnect
close the first terminal and go to START and try again

to find if pin or puk code required

echo -e "AT+CPIN?\r" > /dev/ttyUSB0

if
+CPIN: READY ME......is not pending for any password
+CPIN: SIM PIN ...is Sim code required
+CPIN: SIM PUK PUK1 ..is Puk code required/the device is locked / place the sim in mobile phone to unlock with puck code

To enter Pin code

Code:
echo -e "AT+CPIN=<yourpincode>\r" > /dev/ttyUSB0


example:
echo -e "AT+CPIN=1234\r" > /dev/ttyUSB0

to find if APN's are listed

Codes:
echo -e "ATZ\r" > /dev/ttyUSB0

echo -e "AT+CGDCONT?\r" > /dev/ttyUSB0

Find ISP or Operator
CODE:
echo -e "AT+COPS?\r" > /dev/ttyUSB0

to find operators in area, after the code is entered it will take a while to search

Code:
echo -e "AT+COPS=?\r" > /dev/ttyUSB0

Finally signal strength

echo -e "AT+CSQ\r" > /dev/ttyUSB0

Post all the results possible

[munshi]

thanks alexfish for all the help, but in windows i do not even enter a username, password, pin, puk etc,etc. and the device works perfectly well with both windows and mac devices.
entering these codes i found out the following

echo -e "AT\r" > /dev/ttyUSB0

echo -e "ATZ\r" > /dev/ttyUSB0

ok for both codes.

for

echo -e "AT+CPIN?\r" > /dev/ttyUSB0

+CPIN: READY


to find if APN's are listed

Codes:
echo -e "ATZ\r" > /dev/ttyUSB0

echo -e "AT+CGDCONT?\r" > /dev/ttyUSB0

i got the following

AT+CGDCONT?
+CGDCONT: 1,"IP","internet.vodafone.net","0.0.0.0",0,0
+CGDCONT: 2,"IP","internet.vodafone.net","0.0.0.0",0,1
+CGDCONT: 3,"IP","00000","0.0.0.0",0,1
+CGDCONT: 4,"IP","internet.vodafone.net","0.0.0.0",0,0

OK


on applying echo -e "AT+COPS?\r" > /dev/ttyUSB0

AT+COPS?
+COPS: 0,2,"60202",2

OK


for networks available after echo -e "AT+COPS=?\r" > /dev/ttyUSB0

OK
AT+COPS=?
+COPS: (1,"vodafone EG","voda EG","60202",0),(2,"vodafone EG","voda EG","60202",2),(3,"EGY MobiNiL","MobiNiL","60201",0),(3,"etisalat","etisalat","60203",0),(3,"etisalat","etisalat","60203",2),,(0,1,2,3,4),(0,1,2)

OK

for signal quality after posting echo -e "AT+CSQ\r" > /dev/ttyUSB0


AT+CSQ
+CSQ: 10,99

OK


i hope this answers all the questions you had..and the same device on the same computer in the same area works fine with windows. with goood signal quality and strength

[alexfish]

Hi

the only thing which may not be OK is the signal strength

"10" is boarder line between working and not working (may get errors) , 15 is good , connect the device on usb-cable and try move
to get better signal quality

not sure why network manager re modem-manager not connecting


try these from the terminals

open the first terminal

Codes:

Codes:

sudo killall modem-manager

tr -s "\n" < /dev/ttyUSB0

Open up a second terminal, enter the following codes, note any responses from the first terminal

Codes:

echo -e "ATZ\r" > /dev/ttyUSB0

echo -e "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0\r" > /dev/ttyUSB0

echo -e "AT+CREG?\r" > /dev/ttyUSB0

wait a few seconds, if the device has an led see if it changes

then

now is to try <cid> dial commands

listed according to the locations on the device

+CGDCONT: 1,"IP","internet.vodafone.net","0.0.0.0",0,0 <== ATDT*99***1#
+CGDCONT: 2,"IP","internet.vodafone.net","0.0.0.0",0,1 <== ATDT*99***2#
+CGDCONT: 3,"IP","00000","0.0.0.0",0,1
+CGDCONT: 4,"IP","internet.vodafone.net","0.0.0.0",0,0 <== ATDT*99***4#

the dial code for the first one

Code:

echo -e "ATDT*99***1#\r" > /dev/ttyUSB0

repeat the command a few times until hopefully a CONNECT message , you may have to try

echo -e "ATDT*99***2#\r" > /dev/ttyUSB0

echo -e "ATDT*99***4#\r" > /dev/ttyUSB0

if you get the CONNECT message or CONNECT <number>

enter this code

Code:

sudo pppd ttyUSB0 115200 nodetach defaultroute noipdefault noauth lock usepeerdns ktune

enter your sudo (system )password

see what happens

[munshi]

i moved to a different room in my house where reception is better. and got the following results


in the first terminal after the first code

AT+GCAP
+GCAP: +CGSM,+DS,+ES

OK
AT+GCAP
+GCAP: +CGSM,+DS,+ES

OK
AT+GCAP
+GCAP: +CGSM,+DS,+ES

OK

in the second terminal after coding the following

echo -e "ATZ\r" > /dev/ttyUSB0

OK

echo -e "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0\r" > /dev/ttyUSB0


ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0[/COLOR]

OK


echo -e "AT+CREG?\r" > /dev/ttyUSB0

AT+CREG?
+CREG: 0,1

OK


ON APPLYING echo -e "ATDT*99***1#\r" > /dev/ttyUSB0

OK
ATDT*99***1#
CONNECT


AND I GET THAT FROM THE FIRST ONE

sudo pppd ttyUSB0 115200 nodetach defaultroute noipdefault noauth lock usepeerdns ktune

Using interface ppp0
Connect: ppp0 <--> /dev/ttyUSB0
PAP authentication succeeded
Modem hangup
Connection terminated.

I hope that makes some sense. and a solution to be applied.

[alexfish]

Hi

can you try again with

sudo pppd ttyUSB0 115200 nodetach defaultroute noipdefault noauth lock usepeerdns ktune lcp-echo-interval 0 lcp-echo-failure 0 ipcp-max-failure 30

or

sudo pppd ttyUSB0 115200 nodetach defaultroute noipdefault noauth lock usepeerdns ktune lcp-echo-interval 0 lcp-echo-failure 0 noip novj

also can post the values in ppp options

Code:
egrep -v '#|^ *$' /etc/ppp/options

hi

the field has narrowed a bit , but can you have a look here

LCP: timeout sending Config-Requests (http://pptpclient.sourceforge.net/howto-diagnosis.phtml#lcp_timeout)

look at

your system may have iptables or ipchains rules that prevent GRE transmission

but read the article "LCP:timeout , from top

I could also suggest trying to disable all other eth and wireless connections , try again, then look at the article

i do not mean to be stupid, but i am totally lost with your last post. and reading the article left me even more puzzled. i did not know where is the tunnel, and did not understand what steps to take next.

again sorry for being such a noob, and i hope you can make it a bit more simpler to my simple mind.

[alexfish]

Hi munchi

In most cases vodafone dongles normaly configure and connect with ubuntu
and many more Linux distro without problems.

as Ubuntu 10.10 is a new release it may be a while till
Oops (bugs)to some , get ironed out

Where I sit , the information available is from the what the device returns from
the commands sent to the device, This is one of the advantages of Linux and its
accessibility, something which has been devoid of in other operating systems, that
applies to a lot more than a 3g dongles

don't feel like a noob or feel stupid, everyone using Linux feels that way
at sometime or another. this is the way I feel now , because I don't
have a fix to the problem,other than there a problem with the servers
or a problem with the 64bit set up, the later I suspect

If you are new to Ubuntu , hopefully for a out of box experience try 32 bit version,
see what you think

but make it a priority to try the 3g dongle with the live cd for both 64 bit and 32 bit

Added link: worth reading + the links (also worth reading links to usb_modeswitch and the history behind these devices , still an on going state for novices and the experienced)

thanks alexfish for these comforting words. i decided to try to boot up from the live CD(32-bit) and it worked perfectly. so i decided to try the live 64-bit CD and it worked perfectly too. so i decided to remove and reinstall ubuntu. and it is working perfectly with the USB stick. maybe there was something wrong with the way i installed ubuntu last time or something. but now everything is running smoothly.

[alexfish]

Hi

good news

could you mark your thread as solved, use thread tools at top of page

thanks in advance , enjoy

alexfish

Added , for future reference if you need to debug the pppd (ppp daemon) then add the debug to the line like so

sudo pppd ttyUSB0 115200 debug nodetach defaultroute noipdefault noauth lock usepeerdns ktune lcp-echo-interval 0 lcp-echo-failure 0 ipcp-max-failure 30

but it is not advisable to post this info on forums, as it can reveal passwords etc etc
