I am worried that there is not really a benefit of doing that, just more noise and energy consumption.
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.
