AirPrint is mDNS discovery. Check whether the printer still publishes _ipp._tcp, and whether your phone is even on the same subnet as it.
AirPlay is Bonjour discovery. Two checks from an iPhone separate an Apple TV that has stopped advertising from a phone on the wrong network.
A Roku publishes _roku-rsp and answers SSDP. Checking both from an iPhone separates a device that has left the network from a phone on the wrong one.
Ping the console while it drops, measure the same WiFi from a phone, and find out whether the console is leaving or the whole connection is.
Ping the console while it drops, measure the same WiFi from a phone, and find out whether the Switch is leaving or the connection is.

Firmware, adapter power settings, Fast Startup and the right MAC address, then the packet from an iPhone and a ping to prove it worked.
The Hue Bridge is Ethernet-only, so it lives on whatever subnet its router port belongs to. Two checks from an iPhone find it or rule it out.
Bonjour, a LAN scan and a ping tell you whether the printer left the WiFi, moved address, or just stopped advertising itself.
Bonjour tells you whether the Sonos is still announcing itself; a latency and loss graph tells you whether the WiFi under it is stable.
Separate a camera that left your WiFi from an internet outage that took every camera with it, using a LAN scan, a ping and a record over time.

Casting is mDNS discovery. Two checks from an iPhone tell you whether the device stopped announcing itself or your phone is on a different network.
A plug that drops is usually signal or a moving address. Find which, and keep a record of when it actually happens.
A DNS-only outage passes every connectivity test and fails every name lookup. Here is how to see that from an iPhone, and how to be told next time.
A monitor inside the thing being monitored is not a monitor. Watch Home Assistant from outside, with one URL free.
One speed test proves nothing. A record across the day is what shows peak-hour congestion and what an ISP will act on.
Brief drops need a per-second record, not a speed test. Here is how to catch them and keep the timestamps.
