Just found another bug-report that is related https://bugzilla.redhat.com/show_bug.cgi?id=530764 The issue with modem ZTE MF626, also noted in my trouble-shooting, is also found in the following bug report https://bugzilla.redhat.com/show_bug.cgi?id=533716 I appear to be affected by the same bug. My cellular connection drops out and I am unable to reconnect without a reboot. I used minicom to change from 3G to 2G, but I still could not reconnect. Just as the OP stated, the "the NM icon "blinks" once". I am using a Sierra Wireless 881 PC card. This is on the AT&T network. So what I'll need is some modem-manager debug logs as described here: http://live.gnome.org/NetworkManager/Debugging under the "Debugging NetworkManager 0.8.x 3G connections" section. Basically leave modem-manager running with --debug and try to trigger the dropout, then try to reconnect with NetworkManager from the menu and let me see the modem-manager logs. Created attachment 374934 [details]
modem-manager-debug-output.txt
as requested, and following steps:
Debugging NetworkManager 0.8.x 3G connections
NetworkManager 0.8 and later use ModemManager for 3G device control. To get logs from modem-manager, we use the "--debug" option.
*
Stop NetworkManager
* killall -TERM modem-manager
* modem-manager --debug
*
in another terminal, run NetworkManager like so:
NM_PPP_DEBUG=1 /usr/sbin/NetworkManager --no-daemon
* reproduce the problem
*
send the modem-manager and NetworkManager logs to the developers

Thanks for the logs, both of you. They are consistent so this points to a general modem-manager/NetworkManager issue and is not hardware dependent. I will try to reproduce the issue and debug, thanks! *** Bug 530764 has been marked as a duplicate of this bug. *** The same issues I've had with a Huawei E220 and Huawei E270 3G modems. I've already discussed with "robledo" on FedoraForum.org , and it looks like we have the same issue. I know what's going on and have fixed it in upstream ModemManager already. A few more fixes are required but will show up as a ModemManager update soon. Created attachment 376222 [details]
NetworkManager --no-daemon with DEBUGs
Dan: Unfortunately I use openSUSE 11.2 which contains old NetworkManager (0.7.x). So it may of course contains more bugs and less meaningful debug logs. However I see very similar issue (stage1_prepare_done()) with my Huawei E800.
Are you able to check if this is the same issue or other (and I should update & create new report)?

You might try NM 0.7.2 which has a specific fix for one issue that could cause your problem. The issues described in this bug however are specific to NetworkManager 0.8 snapshots and ModemManager and wouldn't apply to NM 0.7.x. OK, instead of poking with/in old NetworkManager I'll just focus on 0.8. I've downloaded Fedora 12 and tried to connect using LiveCD and my E800. I got some problem with connecting (didn't even try to debug that yet) and second try failed on warn stage1_prepare_done. Could you check once again my logs, please? Is that the same issue this bug is about? Created attachment 376293 [details]

It's already been fixed in the 'states' branch of modem-manager upstream, and I need to do some more testing of that code before I roll out a modem-manager update this week.

I just didn't know if I hit the same bug. OK, but it sounds now I do :) https://admin.fedoraproject.org/updates/NetworkManager-0.7.997-1.fc12,ModemManager-0.2.997-1.fc12 Try at least ModemManager from that update. If for some reason you still have problems reconnecting after a disconnection, I'll need the 'modem-manager --debug' logs. That ModemManager update definitely fixes the "port already connected" problem, but there could be unrelated issues that cause a reconnection failure (for example, some modems seem to want the init string sent twice after a disconnect, and that's only done for ZTE devices at this time). Then we'll diagnose and possibly open a different bug if it's a different problem. NetworkManager-0.7.997-1.fc12,ModemManager-0.2.997-1.fc12 has been submitted as an update for Fedora 12. http://admin.fedoraproject.org/updates/NetworkManager-0.7.997-1.fc12,ModemManager-0.2.997-1.fc12 Just ran Software Update. Problem appears to be solved on my system. :=) Thanks for the work on resolving this issue!

Based on the following thread, I believe Valentin is encountering a different bug than this bug report is about. http://forums.fedoraforum.org/showthread.php?t=234332 Then, as Dan said, another bug should be created with the logs I've provided. Yeah, if you can create another bug. The issue you're having appears to be ModemManager not correctly handling probing when a PIN is required in some cases. I'm having some trouble accessing the "add new bug" page. Please feel free to create another one with the logs I've provided, this issue is starting to be very annoying.....I have to use 'windowz' to do all the internet related stuff. Thank you! ModemManager-0.7.997-1.fc12 seems to work much better now (tested with Nokia E72 & N900). I can connect, disconnect & reconnect from nm-applet at will now.
I'm not sure if this is related to this bug, but it is *HIGHLY* advisable to follow these steps during disconnecting the device:
* "Disconnect" the broadband connection in nm-applet
* disconnect the USB cable
Otherwise NM or MM keeps a lock on /dev/ttyACMx so that it does not disappear when the USB connection is severed. This is kind of strange, because NM says that it is cleaning up the device but there are some dbus error messages:

NetworkManager-0.7.997-2.git20091214.fc12,ModemManager-0.2.997-2.git20091214.fc12 has been submitted as an update for Fedora 12. http://admin.fedoraproject.org/updates/NetworkManager-0.7.997-2.git20091214.fc12,ModemManager-0.2.997-2.git20091214.fc12 Thank you. These kind of actions worked on older versions of NM (connect/disconnect at will), but now the issue is that the 3G modem is not seen as a modem. The 'usbmodeswitch' did not work either. I'm some how stuck and I'm not willing to use Fedora 12 as virtual machine (in a windowz host) just becuase of this error. I hope the 0.7.997-2 versions for NM and MM will fix what I've reported/have.

ModemManager-0.2.997-4.git20091218.fc12, NetworkManager-0.7.997-2.git20091214.fc12 has been pushed to the Fedora 12 stable repository. If problems still persist, please make note of it in this bug report. Nope, it still doe not work. The issue persist (as mentioned in the attached logs + the above comment). I am having the same problem with network manager 0.7.996 and ZTE MF626 3G USB modem . Iwill try to update and see what happens . after update the problem still there but not always .it appears 1 of 3 times 2 other issues happened after the update: usb modem powers off after a while happens ocassionaly (2 times in 2 days ) , and gnome crash while connecting ( happened only once ) I tried network manager in another distro , it only worked if usb modem is connected while . thanks, this is not the case in fedora . I tried using Knetworkmanager but i couldn't connect even after writing dial no and APN . I also updated both NetworkManager and ModemManager to the latest stable available verion in the repository, but still the problem persists. Regards, Shadab (In reply to comment #55) > I also updated both NetworkManager and ModemManager to the latest stable > available verion in the repository, but still the problem persists. Can you please run this command and post the results : rpm -q NetworkManager ModemManager Also, following the directions here: http://live.gnome.org/NetworkManager/Debugging specifically the section about "Debugging NetworkManager 0.8.x 3G connections" and getting modem-manager debug output. Valentin Cobelea; your logs indicate that your device is roaming at the time you make the connection; the roaming provider may not allow your IMEI or have a roaming agreement with your actual provider, in which case the PPP session will fail or the dial will fail, which it looks like it did. nakieb@gmail: I'd like to get some modem-manager debug logs from your device to see what's going on. I also have a ZTE MF626 which works OK for me, so I assume it's just some random bug that we can fix.

nakieb: There is a specific problem here that's unrelated this this bug though, so I've opened bug 578280 for it. |
Created attachment 373742 [details] log of var/log/messages file Description of problem: when manually disconnecting mobile connection with Network Manager, manual reconnections are not possible. However, if the usb-modem is unplugged, and re-plugged, a mobile connection is possible once more. Version-Release number of selected component (if applicable): 0.7.996 How reproducible: very much - in various machines Steps to Reproduce: 1.connect with NM to a mobile connection 2.manually disconnect 3.attempt to reconnect Actual results: nothing (the NM icon "blinks" once) Expected results: reconnection of mobile connection Additional info: in order to facilitate diagnosing the problem, I have inserted comments to the "message" log output as to what I was doing at the Fedora level and with the usb-modems (pluggin, unpluging, etc.). nothing has been deleted. I am posting this here, if anyone can see something. I will also be submitting this to the bug reporting at both the doc attached has output log after carrying out the following steps 1) deactivate the wifi 2) connect Huawei USB-modem 3) connect successfully to mobile 3G network 4) manually disconnect 5) unsuccessful attempt to re-connect to mobile network using NetworkManager 6) 2nd unsuccessful attempt to re-connect to mobile network using NetworkManager 7) unplug Huawei e220 usb-modem 8) plug-in ZTE MF626 usb-modem 9) eject automatic mount of usb-mass-storage, in order to recognize ZTE usb-modem 10) connect successfully to mobile 3G network 11) manually disconnect 12) unsuccessful attempt to re-connect to mobile network using NetworkManager 13) reactivate successfully wifi with NetworkManager 14) unplug ZTE MF626 usb-modem The version of my current NetworkManager is 0.7.996 (is this actually 0.7.1.996 ?? from Oct.2009??)
