Would never happen -- to me... "water heating system" and "internet connection" have no business mixing in my book. Just like "automobile" and "telemetry" or "phone app" and "registration" or "face recognition" in "public".
Just because it -- "can", doesn't mean you -- "should".
I must.
On the wider dual-band single SSID, I see that as a bit dicey. Not from a laptop/phone standpoint, but from an IoT "thing" standpoint. My wifi- router (a Tplink -- do not recommend) does this and it's firmware/web- interface can monitor connections on both presenting the same SSID. When you start bringing in IoT devices, that has always been a big "FLASHING RED WARNING" light to me given the history of security issues with IoT devices (hardcoded credentials, etc..)
My two devices have no hardcoded credentials.
While most premium devices handle dual-band just fine (phones, laptops, etc..), the "patched together" IoT devices don't. That "don't" part is still a big "FLASHING RED WARNING" from a security standpoint on just what could piggy-back into my network through its protocol.
I don't see any security issue in them not doing 5 Ghz.
I guess the tech-adventurous and generations coming up behind have no issue with everything being able to transmit to the world, but as a child of the 60's call me just a bit skeptical of the tradeoffs being made.
(though if I'm ever faced with the issue [doubtful], I'll remember the advise :)
You can put them on the guest network. Properly done, they don't have access to anything at your home. If you are still paranoid, put them on a totally different router. -- Cheers / Saludos, Carlos E. R. (from 15.5 x86_64 at Telcontar)
