Log output of NetworkManager service when connection fails
This message is a reminder that Fedora Linux 36 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora Linux 36 on 2023-05-16. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a 'version' of '36'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, change the 'version' to a later Fedora Linux version. Note that the version field may be hidden. Click the "Show advanced fields" button if you do not see it. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora Linux 36 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora Linux, you are encouraged to change the 'version' to a later version prior to this bug being closed. Fedora Linux 36 entered end-of-life (EOL) status on 2023-05-16. Fedora Linux 36 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora Linux please feel free to reopen this bug against that version. Note that the version field may be hidden. Click the "Show advanced fields" button if you do not see the version field. If you are unable to reopen this bug, please file a new report against an active release. Thank you for reporting this bug and we are sorry it could not be fixed. For the record: Yesterday, I upgraded to Fedora 38 (skipped 37), and with NetworkManager 1.42.6-1.fc38, the problem isn't there any more. Establishing an internet connection with the same WWAN device, SIM card and carrier, no works as expected. |
Created attachment 1907814 [details] Output of mmcli -m 1 Description of problem: Since upgrading to Fedora 36 (from 34), NetworkManager isn’t able to establish a mobile broadband connection (LTE, 4G)) via my WWAN card (Sierra MC7710). It used to work fine on Fedora 34 with the same hardware, same carrier, same SIM card. Version-Release number of selected component (if applicable): 1.38.4-1 How reproducible: Always, when using the setup described above. Steps to Reproduce: 1. Make sure that a working SIM-card is inserted into your WWAN card. 2. Set up a gsm connection using `nm-connection-editor`. 3. Make sure that the WWAN card is enabled (e.g. using rfkill), and powered up. 4. Use `nmcli con up` or the NetworManager GUI to activate the gsm connection. Actual results: No connection to the internet over LTE (4G). Expected results: I expect NetworkManager to successfully establish a connection to the internet over LTE (4G). Additional info: I attach some output from ModemManager (mmcli) and the journalctl log output when trying to establish a connection using NetworkManager (after setting the log-level to DEBUG using the command `sudo nmcli general logging level DEBUG domain ALL`). I also tried to put the SIM-card in a mobile phone to confirm that the phone would be able to establish an internet connection - that worked fine. Also, the SIM-card is not protected (no PIN is set).
