https://bugzilla.suse.com/show_bug.cgi?id=1217495 Bug ID: 1217495 Summary: WiFi fails to re-connect on return from suspend, occasionally. Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.5 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Network Assignee: screening-team-bugs@suse.de Reporter: carlos.e.r@opensuse.org QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- Created attachment 870981 --> https://bugzilla.suse.com/attachment.cgi?id=870981&action=edit journal showing the event Some times, when thawing my laptop, it fails to connect to the WiFi. Looking at the log, this might look a router issue, but the thing is, it has happened to me on two routers, one in Ottawa, another in Madrid. And hibernating the machine makes the WiFi connect again (power cycles the chipset). Thus I believe the problem is in the laptop/linux side, not the router. Laptop is less that a year old, a Lenovo L14 Gen3 AMD. I will attach journal showing one such incident. Some lines removed for privacy.
