I'am in kernel 5.8.3.

Today I updated from .2 to .3.
I had not used wireless from a long time (+1 year) in this notebook.
So when I successfully connected to the router,  and started browsing,
I had a complete freeze of my system. Not even ssh access.
Later  I had the same complete freeze when I closed the lid; when I
went back to the device it was completely frozen.
journalctl -b -1 --system does not throw anything significant, no
indication of a kernel panic.

Now I am back to wired connection and no problems so far. So I suspect
it's the wireless card.

Has anyone been experiencing this issue in the aforementioned kernel version?
