Typically you have main and guest to isolate them You also have different networks for different bands because they use different radios (2.4GH and 5GH) with both having tradeoffs of range and speed. Some have triband as well so that you can isolate high performance devices because every device on a network increases latency slightly, and more so a radio only support one broadcast method at a time and will downgrade its self to the least common dominator for the devices connected to it.
You don’t need to have different SSIDs for 2.4 and 5 ghz. They can be the same and the device will handle the connections.
Oh what? Dope.
Yeah depending on your WI-FI device, it might even have tools to steer devices onto specific bands. But without that, the end user devices do a semi decent job. It’s basically so that if you’re connected to 5ghz with good signal, and walk to a different part of your house it can just switch over to 2.4ghz.
The big key is your hardware needs to support it. Back when “unified SSIDs” became a thing, some older 802.11n (WiFi 4) and ac (WiFi 5) devices could do it, but it was…. Weird.
If you have a newer router, especially WiFi 6 or 802.11ax it should be be to do the unified SSID.
