Some further information:
I actually never use the laptop's modem.
I initially noticed that there is something wrong with ModemManager
because after the Fedora 37 Beta upgrade,
I started receiving great amounts of SELinux denials of the following form:
type=AVC msg=audit(1663963395.193:1911): avc: denied { execmem } for pid=14946 comm="ModemManager" scontext=system_u:system_r:modemmanager_t:s0 tcontext=system_u:system_r:modemmanager_t:s0 tclass=process permissive=1
I believe that denial is triggered by ModemManager service crashing.
I have not been able to reproduce it by manually running ModemManager.
Actually, it looks like just updating to the latest point release would fix the issue. The problem is mentioned as the very first item in 1.18.12 announcement: https://lists.freedesktop.org/archives/modemmanager-devel/2022-September/009419.html *** Bug 2133733 has been marked as a duplicate of this bug. *** Similar problem has been detected: At login with no user interaction reporter: libreport-2.17.4 backtrace_rating: 4 cgroup: 0::/system.slice/ModemManager.service cmdline: /usr/sbin/ModemManager crash_function: g_malloc0 executable: /usr/sbin/ModemManager journald_cursor: s=5c6a9255d2a24d7c8b5e34079497078c;i=612b;b=1bd7c7e3fd804a27bdcab08402e0bc0c;m=26d298c;t=5eb8bbffb124d;x=dd935d6cff7ff96c kernel: 5.19.15-301.fc37.x86_64 package: ModemManager-1.18.8-2.fc37 reason: ModemManager killed by SIGABRT rootdir: / runlevel: unknown type: CCpp uid: 0 Created attachment 1919832 [details]
File: backtrace
I second the suggestion from Comment #2: "updating to the latest point release would fix the issue" I have built the 1.8.12 from sources and it works (for me). ... addendum to Comment 6: on a PC, not using a laptop As a work-around, I downgraded Glib2 to the last known working version, which is available from Koji. rpm -i --nodeps --force glib2-2.73.1-2.fc37.x86_64.rpm My internet connection works now, but note that doing this is inadvisable because it can break many other parts of your system. Forget my previous comment, I clearly don't know what I'm talking about. ModemManager just happens to work sometimes. It's possible to initialize the modem by booting into another distribution that has a working ModemManager, and then reboot into Fedora. After that the connection seems to always work. Sleep mode messes it up.
