I think the RedHat bug (517442) may not be related to this bug at all.
This bug was not specific to the E620. In fact, it appeared to be a
general issue affecting users of any GSM modem.
Most people commented here or marked this bug affects me only to avoid
reporting duplicate bugs. For instance,
Okay, seems like you are right. But it is not correct that all modems
have troubles reconnecting. It works fine with most of my modems. I have
just experienced it with an Ericsson module. So please add debug logs of
this specific modem, or report new bug reports for other modems:
I open the Ubuntu task again, as the RedHat bug report referred to above
indicate that upstream supports the modem.

I use a script to reconnect my ONDA 3G modem, because the solution above
doesn't work for me. My script is executed by cron, every 5 minutes.

You don't have to reboot, killing modem-manager will be enough most of

Could the importance of this bug be set to high? Ubuntu is basically
unusable, when you have to reboot on every disconnect.

There's at least one issue with such a patch, which makes it
unacceptable as it is: using this, if a device is marked failed because
of an invalid PIN, you'd end up locking the device and requiring PUK
entry -- not all that good ;)
Let's keep figuring out how this can be dealt with in a better
It doesn't seem to be fixed in Oneiric either. I've looked into the
source code in oneiric, and it doesn't look like the patch has been
submitted.
I would very much like to test this and get it fixed somehow.

Does this patch work in Natty? I have the same problem with my Qualcomm
Gobi 2000 module. It disconnects and the device disappears for a little
while (30 seconds or so) and then reappears and I have to re-connect my
mobile broadband connection manually.

The problem is that when a device switches from any state besides the
final CONNECTED state to the FAILED state, networkmanager marks the
connection as invalid to avoid it from reconnecting over and over.
However, this behavior is not sane when the connection type is mobile
broadband, as the

Sorry, I should clarify the problem above. I can connect to my 3G ISP
using the E1762 modem but after a disconnect from the provider an
attempt at connecting again fails. Either power cycling the modem by
unplugging it or restarting modem-manager then allows network manager to
once again
I am also having this problem with Ubuntu 10.04 and a Huawei E1762
modem. My provider likes to terminate the PPP session for no reason
anywhere from 1 minute to 2 days after a connection eg:
Aug 31 08:25:30 myth pppd[2313]: LCP terminated by peer
Aug 31 08:25:30 myth pppd[2313]: Connect time
I have the same problem with two Huawei umts sticks and an internal umts
modem (Samsung). The modem connects for the first time, but won't a
second time most of the times. Killing modem-manager solves the problem.

USB Modem wont connect after modem hangup
Using Network Manager? What happens if you right-click on it and untick
the Enable Mobile Broadband box? For me, that allows reconnection
without unplugging - although not ideal of course. (I guess it kills
modem-manager, from what ehasenle said.)
The really annoying thing is that with Ubuntu
I have the same problem. This error appears after reconnecting a few
times. The error is more frequent if the connection fails once due to
GSM network problems. After the error appears the modem does not work
again until I kill the modem-manager.
