I set up the Raspberry Pi with a connection to my router and it shows that it is connected with tooltip:

wlan0: Associated with <ssid>
wlan0: Configured 192.168.1.<N>/24
eth0: Link is down
docker0: Link is down

From my machine, pinging to raspberrypi.local returns nothing (10 minutes ago it returned the IP) and an SSH connection does nothing or throws an error.

I checked that both machines are connected to the internet.

$ ping raspberrypi.local
ping: cannot resolve raspberrypi.local: Unknown host
$ ssh -i ~/.ssh/rpi [email protected].<N>
ssh: connect to host 192.168.1.<N> port 22: Operation timed out 
$ ssh -i ~/.ssh/rpi [email protected].<N>
ssh: connect to host 192.168.1.<N> port 22: No route to host

The raspberry Pi showed a connection for longer than it was connected. When I tried again, it was no longer connected and could no longer connect to the router. The connection between the Pi and the router was across a courtyard and possibly heavy rainfall had disturbed the 5G connection, as this site mentions:

The weather condition that has the greatest effect on a Wi-Fi signal is rainfall, particularly for wireless setups using the 2.4-GHz radio frequency. Water droplets absorb this radio frequency and partially block the signal. Anecdotal evidence from communities with light-pole-based public Wi-Fi suggest that rainy days had an impact on signal strength. Even so, Wi-Fi signals are short range and usually deployed indoors. While rainfall can create interference -- in much the same way that it limits visibility for human eyes -- attenuation due to distance from the router is a much likelier culprit for low signal strength.

I restarted the Pi and it worked. I could have also moved it closer to the router or used an ethernet connection.
