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.
