alt Hacker News> and for whatever reason 2.4ghz only devices cant find the SSID unless you if there is a name conflict on the 5ghz frequency
Huh? Is this true? It doesn’t make intuitive sense to me—if the device doesn’t have a 5ghz radio I would expect it to be physically impossible for the 5ghz network to interfere.

It's called Band Steering and it messes up older devices. Its truely an L direction that the wifi industry has gone, its a reaction to overcrowding of the 2.4Ghz spectrum by automatically moving capable devices to the 5Ghz SSID
so happens that its not backwards compatible very well to 2.4Ghz only devices. Not because of the frequency itself but because of the band steering implementation from the router

I've had this issue too on older devices, until I made the SSIDs different by suffixing 2ghz and 5ghz to each one. I think I've had it happen both on an older Android and older MacBook but it was a while ago, could be misremembering.
