Configuring Huawei E173 on Natty

[Lars Noodén]

Where can I find details of how to set up a Huawei E173 on Natty?

The network interface's status icon shows first "waiting for authorization" then it goes to "not connected"

The modem hardware is showing up when it is plugged in:

$ ls -la /dev/ttyUSB*
crw-rw---- 1 root dialout 188, 0 2011-04-28 19:18 /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 1 2011-04-28 19:18 /dev/ttyUSB1
crw-rw---- 1 root dialout 188, 2 20$ lsusb|grep Huawei

Bus 001 Device 013: ID 12d1:1436 Huawei Technologies Co., Ltd. 
11-04-28 19:18 /dev/ttyUSB2

What needs to be done to get it working?

[Lars Noodén]

Except for a brief time, once so far, the network interface icon always shows the modem being 'not connected' The modem connects ok in OS X. In kubuntu, it gets as far as 'preparing to connect' and the drops back to being 'not connected'

Hi

I have not upgraded to Natty so not sure if all commands to list the device will work

but can start by looking up the device with the usb-devices command

usb-devices

post the results

of note from the listings

$ ls -la /dev/ttyUSB*
crw-rw---- 1 root dialout 188, 0 2011-04-28 19:18 /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 1 2011-04-28 19:18 /dev/ttyUSB1
crw-rw---- 1 root dialout 188, 2 20$ lsusb|grep Huawei

Bus 001 Device 013: ID 12d1:1436 Huawei Technologies Co., Ltd.
11-04-28 19:18 /dev/ttyUSB2

Need to ask if at any stage, did you disconnect the device whilst issuing the commands

can see if the nm-tool command works

nm-tool

only post the results applicable to the device

Hi

everything seem ok at kernel level (with exeption of other ports . it seems to have alternate interface ) does it have wifi connection abilities.
looks as if Network Manager is selecting the correct port
I am assuming the Network Manager details are correct (double check )
if the details are correct, then so not sure problem with modem-manager or the pppd

can monitor the syslog to see if any thing shows (with reference to the message "waiting for authorization"). can check the the authentication (in NM ,PPP settings)
can post the results of

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

can suggest installing Sakis3g

http://www.sakis3g.org/

see what happens

There's a lot happening in syslog when the networking manager tries to connect, about 100 lines worth.

Apr 30 18:23:17 kubuntu NetworkManager[890]: <warn> GSM connection failed: (32) Unknown registration status response

Hi

going to try and connect this device via the terminal, but first require some info about the modem

allow time for the system to settle (let modem manager finish it's probing)

open up a terminal and enter the follow code

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

open up the second terminal and enter the following commands , the results should appear in the first terminal

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

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

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

echo -e "AT+COPS=0,2\r" > /dev/ttyUSB0

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

post the results from the first terminal

[Lars Noodén]

post the results from the first terminal

I added echo -e "ATI\r" > /dev/ttyUSB0

OK
AT+CREG?
ERROR
AT+CGDCONT?
ERROR
AT+COPS=0,2
ERROR

Manufacturer: huawei
Model: E173

It's been a long time since I worked with modems.

[alexfish]

Does the modem have a pin code

check the sim pin stat

echo -e "AT+CPIN?\r" > /dev/ttyUSB1
