Bug Description

Under 9.04, I could successfully use my Zoom and U.S. Robotics USB modems with the following installations:

First, Gnome-ppp (sudo apt-get install gnome-ppp)
Second, from Linuxant.com: dgcmoden 2.22 k2.6.28 generic ubuntu 386.deb.zip

After upgrade to Karmic Koala, I see the following in the terminal window:

john@john-laptop:~$ sudo gnome-ppp
[sudo] password for john:
WVCONF: /root/.wvdial.conf

I have a similar experience with my USRobotics USR5637 dialup USB modem, which worked perfectly under Jaunty. After upgrading to Karmic yesterday, gnome-ppp would fail to detect this modem. Once or twice when I rebooted, gnome-ppp would find the modem, but when I connected the system would drop the connection after some seconds or minutes, losing the modem again. This behavior seems very similar to what has been reported in Bug #449394 involving a Huawei E220 modem. Following experiences in that thread, I rebooted my machine into an older kernel (2.6.28-15 instead of 2.6.31-14) which allowed to connect using the modem again, though it still seems a little prone to dropping the connection after a while.

Changed in ubuntu:
status: New → Confirmed

usb modem manufacture seems not to matter. My U.S. Robotics 5637 fails as well as my Zoom 1061.
Also, both worked under Ubuntu 9.04, Gnome-ppp and the Linuxant dgc driver

And yes, I've rebooted post install of the USR modem. I've got a nice power light showing on it. I've got both usb-storage and usbserial drivers - e.g.

~$ modprobe -l usbserial
kernel/drivers/usb/serial/usbserial.ko
~$ modprobe -l usb-storage
kernel/drivers/usb/storage/usb-storage.ko

Even so, GNOME PPP just *CANNOT* find/detect the modem! Under Applications -> Systems Tools -> Device Manager, showing 'properties' (for the USB Modem's Serial Port) reveals that this hardware shows up as /dev/ttyACM0. Manually entering /dev/ttyACM0 (into GNOME PPP) and pressing the Detect button generates a complaint about 'No Modem found in your system'.

Trying to go direct to /dev/ttyACM0 via gtkterm generates a 'Device or Resource Busy error' ... and this looks like it might relate to this nasty problem: http://ubuntuforums.org/showthread.php?t=1325677 (and maybe this too http://ubuntuforums.org/showthread.php?t=1296460). Does this really have something to do with the removal of some hardware abstraction layer (HAL) in Ubuntu 9.10 (Karmic Koala)?

I'm astonished that using a (new but proper) USB modem (as opposed to a half-baked WinModem) would soak so much time/effort. Does anyone have a suggestion about next steps (and/or further diagnostics/debugging). I'm sort of getting down the bottom of my bag of easy tricks ... and I'd hate to start *REALLY* sinking time into something as tangential/trivial as a PPP dial up connection. Geesh. It is 2009 ...

As Steffen noted, I ran into same problem (visit the bug I filed and he pointed to).

Temporary work-around is to:

sudo apt-get remove modemmanager

But this makes NM incapable to detect and automatically set up "mobile wireless connections". I don't care because I can dial mobile connection using old good wvdial...

Back to using Ubuntu 9.04, again, with gnome-ppp and the linuxant usb modem driver.

It is successful, and I am online with the Zoom dial-up usb modem at 43,000 bps.

I'll stay with what works, until I read the solution to Ubuntu 9.10 has been found. It must be the
distro, since gnome and dgc work perfectly under the previous one:

     I've posted quite a number of tips that might help with this over at https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/482971. I've managed to get pppd going (and confirmed operation via ping via both DNS and direct IP addresses) ... but for me, I'm still watching my pppd fight with my ISP over what should be a static IP address. My set up only works with Ubuntu 9.10 via a dynamic (pppd negotiated) IP address (... and that won't do for me). To recap:

     1. modem-manager package must be completely removed (and system rebooted). Modem manager squats on devices that it fails to recognize on ADSL modems (e.g. regular USB Modems).
     2. Neither GNOME-PPP nor wvdial will work (but 'pon' and 'poff' and direct 'pppd' invocations *do* work). With gnome-ppp and/or wvdial, I get errors about 'Serial Link is not 8 bit clean' (see http://ppp.samba.org/ppp/FAQ.html).
     3. /usr/sbin/pppd is group 'dip' ... so be sure to make your user account a member of group 'dip'
     4. Make sure that neither gnome-ppp/wvdial nor network manager have put something like auto ppp0 into /etc/network/interfaces file. If so, comment that out (by hand).
     5. Make /etc/ppp/pap-secrets and /etc/ppp/chap-secrets at least readable by group 'dip'
     6. If using the excellent 'wvdialconf' command, grab the local .wvdial.conf file and hand integrated it into /etc/wvdial.conf. For the most part, one can just overwrite the /etc/wvdial.conf file that comes with Ubuntu 9.10 (by default).

Good luck, Steffen.

I can confirm that the workaround of removing the modemmanager package does the trick for me, allowing me to use my USRobotics USR5637 dialup USB modem with gnome-ppp without problems in Karmic. I did not have to "completely remove" the package in Synaptic, only doing a regular package removal. This workaround probably leaves my system unable to talk to wireless 3G modems, but that is not an issue I can test or need to face.

First, load the needed software (using a dsl connection):

sudo apt-get install gnome-ppp

go to linuxant.com and get a dialup modem driver:

click on drivers tab to get conexant chipsets, on next page, click left column DGC (modem) driver first installation and download, instructions. Pay close attention.

Now you have a graphic modem program and a driver.

Next, remove the "modemamanager"

sudo apt-get remove modemmanager

Finally, when you want to use your modem, get a terminal window and enter:

sudo apt-get gnome-ppp. Then enter your dialup, phone number, id and password and click "connect."

I hope this helps.

You are not supposed to install dgc, the karmic kernel should support dgc modems natively.

Also, you need to uninstall the modemmanager package in karmic for the modem to be detected properly.

Did you reboot after removing modemmanager and before trying gnome-ppp?

I thought I did, but it is possible that I did not. The previous code does
not go away, I guess,
until a "new" operating system is started.

I uploaded and installed ubuntu 9.10 again. I removed gnome-ppp:

sudo apt-get remove gnome-ppp

I removed modem manager

sudo apt-get remove modemmanager

I re-booted.

I installed gnome-ppp

I entered my isp id/password, and selected ACM0 as the modem device, and 57000 bps as the speed.

I re-booted.

I dialed up as the super-user for gnome-ppp.

It worked:

Great news that it's working!

I'm closing this bug as per your last comment.

By the way, you should run gnome-ppp as your user, not as root.

Changed in modemmanager (Ubuntu):
status: Confirmed → Fix Released

I will try using gnome-ppp at the user level rather than root. In the
past, user level has failed and only super user, root, would work.

I understand working at the root level gives others acces to my system since
I open it myself
with my login adn password.

Thank you for your help. I was a blind person walking in a forest bumping
into trees.

Gnome-ppp still requires removal of modem manager:

sudo apt-get remove modemmanager
Zoom dialup modem to the web:
