Roger, you hit the nail on the head. After reviewing a bunch of old logs, it seems that
I've been having intermittent connection drops for a while (i.e., while still on F34).
Previously, it seems it would just reconnect on 5 GHz - the change in F35 is that it now
toggles between 5 and 2.5 and when it does, it changes my IP address, so I definitely
notice.
What decides to switch frequencies - is that wpa_supplicant? NetworkManager?
