What is strnage is that there was no iwlwifi driver change in this
interval. Only iwlegacy (don't know if this one was used instead).

Note, my laptop uses iwlwifi as well. I've met random issues with it
a year ago when I started to use wifi, such as wifi randomly freezing
during audio meetings, and automatically fixing itself after 1 minute.
I also found that a down-up cycle on the interface would fix it. It
happened less than once a day so it was not easy to diagnose, and given
how crappy all wifi chips are, I naturally attributed this to the
hardware. But since I upgraded to 5.4 months ago, I don't remember having
met that issue anymore, so it was likely related to the driver. All I can
say is that 4.19.68 was exhibiting this issue. I can't say for older ones
because I didn't use wifi before.

Just my two cents,
Willy
