Is this a regression? (That is, did it work before?) I know WWAN modems run into a lot of difficulties with regulatory compliance and are often hard to get with open source drivers. I know Lenovo is still working on support for the models they ship with Fedora Workstation preinstalled.
In today's Prioritized Bugs meeting, we agreed to reject this as a prioritized bug as hardware enablement is generally not a qualifier for prioritized bug status and the effect is not widespread. https://meetbot.fedoraproject.org/fedora-meeting-1/2021-03-24/fedora_prioritized_bugs_and_issues.2021-03-24-15.05.log.html#l-55 Thank you for nominating it. We agree that this is a good thing to fix and encourage you to post about it in the Lenovo forums: https://forums.lenovo.com/t5/Fedora/bd-p/lx04_en
It looks like it's based on the Intel LTE Modem which doesn't have support yet in the upstream kernel. The initial underlying, not support specific modems, platform has finally been posted upstream. Given it uses the MBIM interface there's likely no work to be done by ModemManager, in theory when the support lands in the kermel it should just work. https://www.spinics.net/lists/linux-wireless/msg210149.html
Should work with 5.14.x but probably also needs ModemManager 1.18.x so it should be supported with Fedora 35. Please test.
Hi the last package available in FEdora 34 is [ealcaniz@ealcaniz ~]$ rpm -qa | grep ModemManager modem-manager-gui-mm-ModemManager-0.0.20-3.fc34.x86_64 ModemManager-glib-1.16.8-4.fc34.x86_64 ModemManager-1.16.8-4.fc34.x86_64 [ealcaniz@ealcaniz ~]$ When you said it Should work with 5.14.x ? what package? How I can test the package?

This message is a reminder that Fedora 33 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 33 on 2021-11-30. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 Fedora 'version' of '33'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 33 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, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Thanks, I am using Fedora 34 and the issue still happening. I think it is resolved in Fedora 35.
