Bug ID: 411220
Summary: No wired connection available after suspension
Product: plasma-nm
Version: 5.16.4
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: jgrul...@redhat.com
Reporter: rubs...@gmail.com
Target Milestone: ---
SUMMARY
After the recent updates, whenever my laptop wakes up from suspension, wired
connection (via Ethernet adapter) is not restored and completely vanishes from
the connections list in Network Manager (as if the wire has been physically
disconnected).
So far, I haven't found any way to restore it, which is insanely annoying.
- Reconnecting the wire doesn't work;
- Restarting "NetworkManager" and/or "networking" services doesn't help, but
introduce more bugs (wireless connection stop working due to missing secrets);
- Replacing "plasmashell" doesn't affect it;
- Judging by "ifconfig" output, the Ethernet interface is UP and completely
functional after suspension.
STEPS TO REPRODUCE
1. Suspend to RAM.
2. Wake it up.
OBSERVED RESULT
Wired connection no longer works and is not visible in Network Manager.
EXPECTED RESULT
Wired connection to work normally.
