Connecting through huawei gsm-usb-modem not working (stops after Stage 4)

[Tobias Pflug]

On a laptop running Ubuntu Karmic (all updates installed as of today)
NetworkManager fails to establish an internet connection using a
Huawei 160 (reported by `lsusb` as E220/270) USB/HDSPA modem.
(The same works fine under Jaunty)

Steps to reproduce:

1. Plug in the huawei usb stick and follow the network manager setup steps
 selecting Germany / FONIC as provider and enter PIN number. Other
 settings remain as-is - login and password remain empty.

2. Select connect in the network-manager applett

3. After some time the usb-stick will indicate through constant blue
   LED that a connection has successfully been established however
   the network manager does not report establishment of a connection.
   The applet icon is still animating indicating a "connecting.." state.

Details:

Nothing changes after step 3 until I cancel the connection. Looking at the
output of /var/log/messages and /var/log/daemon.log it appears that
network manager only gets to Stage 4 but Stage 5 (Committing IPv4 Config)
never actually starts nor does the log display its scheduling.

If I specify some random username and password network manager will segfault.
No further details on this right now

I have 2 usb modems, a Zoom usb and U.S. Robotics usb modem. Under Ubuntu 9.04,
I must install gnome-ppp:

sudo apt-get install gnome-ppp

Then go to Linuxant.com for a driver:
(conexant chipsets).
2.6.28-15-generic (kernel version)

dgcmodem_1.11_k2.6.28_15_generic_ubuntu_i386.deb.zip (driver)

When installed, both modems connect to wvdial, get dial tone, connect and run.

Under Ubuntu 9.10, the software responds "modem not found"

Under 9.04, again, it works perfectly. I wonder why. Was there a kernel change that affects PPP?

Thanks.

I have made the following two scripts (from pages found on ubuntu.org) that get my Huawei E220 (and probably many others) on the net without problems:

In your home folder you make a file called:

Put the following in /etc/wvdial.conf
---------------------------------------------
[Dialer cell]
# This configuration should work for most cellular modems and
# USB or bluetooth connected mobile phones.

# Most services/devices dial with *99# . A few seem to require *99***1#
Phone = *99#

# These often suffice, but your ISP might require different details. They're
# often dummy details used for all users on the ISP, frequently the ISP's
# name, but some ISP's do require you to use a real username and password.
Username = foo
Password = foo
Stupid Mode = 1
Dial Command = ATDT

# Your modem device. Usually /dev/ttyUSB0 or /dev/ttyACM0
# Bluetooth devices use an rfcomm device (/dev/rfcomm0, etc) that must be set
# up first.
#
#Modem = /dev/rfcomm0
#Modem = /dev/ttyACM0
Modem = /dev/ttyUSB0

# Port speeds that're worth testing:
#Baud 921600
Baud = 460800
#Baud 115200
#Baud 57600

# If your SIM card has a PIN, comment this line, uncomment the next one, and
# change the PIN shown to your PIN. If your modem cannot read the pin-code,
# you may put the card in your cell phone and remove the pin request. Then
# ATZ will do. (Consider carefully if this is a good idea.)
#Init2 = ATZ+CPIN="0000"
Init2 = ATZ

Init3 = ATE0V1&D2&C1S0=0+IFC=2,2
ISDN = 0
Modem Type = Analog Modem

# If you know your ISP's APN, specify it instead of YOUR_ISP_APN below.
# If you don't, you may be able to find out on the 'net, or from tech
# support.
# There's also an APN table at https://wiki.ubuntu.com/NetworkManager/Hardware/3G .
# If you can't find it, you might be able to dial out without setting an APN
# (especially from a mobile phone). Just comment this line and uncomment
# the next one.
#Init5 = AT+CGDCONT=1,"IP"
Init5 = AT+CGDCONT=1,"IP","YOUR_ISP_APN";
-------------------------------------------

Now, as root put the following script in /usr/local/bin

If you name the script
huaw
you must make executable:
sudo chmod u+x /usr/loca/bin/huaw

The script huaw
------------------------------------------
#!/bin/bash
#You must configure the following variables:
#Check with ifconfig
#Wired device
WI='eth0'
#Wireless device (probably wlan0)
WL='eth1'
#Checkout you vendor and product on:
#https://wiki.ubuntu.com/NetworkManager/Hardware/3G
VE='0x12d1'
PR='0x1003'

#Kill old wvdia-connections
killall wvdial

#Then kill any wired or wireless connection so that
#they don't interfere with your route table
ifconfig $WI down
ifconfig $WL down

#Uninstall and re-install the driver in order to ensure
#that the device /dev/ttyUSB0 is active
rmmod --force usbserial
modprobe usbserial vendor=$VE product=$PR

#start the connection with wvdial
#the dialup script must be in ~/.wvdialrc under [cell]
wvdial cell &

#route packets to the gateway-ip that is under P-t-P
#in ifconfig
A=`ifconfig | grep -A 2 ppp0 | grep P-t-P`
A1=`expr index "$A" P`
B=${A:$A1}
A2=`expr index "$B" M`
A2=$(($A2-6))
C=${B:5:$A2}
echo "Gateway: $C"
route add default gw "$C"
---------------------------------------------------...

Hi Tobias,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/ . If the issue remains, please run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 413989

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

[This is an automated message. Apologies if it has reached you inappropriately; please just reply to this message indicating so.]

[Sebastian Nohn (sebastian-nohn)]

Works with 10.10.

[Po-Hsu Lin (cypressyew)]

Closing this bug with Won't fix as this kernel / release is no longer supported.
Please feel free to open a new bug report if you're still experiencing this on a newer release (Bionic 18.04.3 / Disco 19.04)
Thanks!
