Huawei E270 HSPA Get's detected but connection fails

[Bas Grolleman]

Description: Ubuntu intrepid (development branch)
Release: 8.10

Ok, after updating to the latest packages my HDSPA card stopped working, it's still detected but when I try to connect it attempts to do this for less then a second and gives up. It was working fine before the update, except for some DNS issues once in a while.

I did remove the configuration in network manager and added a new one. (Seems that the latest update should fix my DNS issue, since it can be provided now)

Card is a Huawei Mobile Connect from KPN Mobile, Netherlands.

I did a reinstall today from the Ubuntu Intrepid Beta and UMTS works fine, it however breaks again after updating the system to current using apt-get.

Could anybody help out and atleast give me some pointers on how I should debug the issue. Sending basic commands lilke ATZ work, but others like ATDT didn't have an effect.

[Bas Grolleman (bgrolleman)]

Ok, after spending a few hours greping and searching and comparing with the Vodafone connect software, I got it to work.

#!/bin/bash
echo "ATZ^M" > /dev/ttyUSB0
echo "CPIN=0000^M" > /dev/ttyUSB0

Seems something goes wrong with sending the pin number, I'm at the office now but I will try and see if I can reproduce this on the way home.

[Bas Grolleman (bgrolleman)]

Ok, after a new check it seems I need to send

ATZ
AT+CPIN=0000

After I do that the modem works fine with networkmanager. I already tried filling in my PIN in the configuration dialog, but this doesn't seem to have any effect.

please become root like:

sudo su

and run:

/etc/init.d/NetworkManager stop
NM_SERIAL_DEBUG=1 NetworkManager --no-daemon 2>&1 | tee /tmp/nm-serial.txt

and attach /tmp/nm-serial.txt

[Bas Grolleman (bgrolleman)]

I tried connecting multiple times, hope this is enough info

plesae file you mm-serial against NetworkManager in bugzilla.gnome.org and give us your bug id.

I had the same problem with the Huawei E870 (KPN internetkaart 820) A simpel sollution can be: remove the pin code from the SIM card. I did this by placeing the SIM card in a cellphone and in the settings menu, disabele the pin code.

so we need a backport of revision 4222 ... lets try that:

viewvc:
http://svn-archive.gnome.org/viewvc/NetworkManager/trunk/src/nm-gsm-device.c?r1=4222&r2=4221&pathrev=4222

patch:
http://svn-archive.gnome.org/viewvc/NetworkManager/trunk/src/nm-gsm-device.c?view=patch&r1=4222&r2=4221&pathrev=4222

 Attempt to compensate for modems that don't enable full AT parsing before
 the PIN has been entered.

 * src/nm-gsm-device.c
  - (init_modem): accept different init strings
  - (init_done): try different init strings on failure
  - (check_pin_done): on PIN success, do full modem init

This should be fixed in Jaunty now. Thanks for reporting.
