I’ve got some smart home devices that need to be setup by another device on the same WiFi network, but it has to be 2.4ghz network. My modern android phone insists on connecting to the 5ghz network and so can’t complete the setup.

Currently, I use an old android tablet that only connects to 2.4ghz to get round this, but it’s clunky. Previously I’ve changed the WiFi network to produce seperate ssids for the two bands, but I’d rather not have to switch these settings around everytime I need to modify something.

What I want is a system setting in android or an app that forces my phone to turn off its wireless N capabilities and only use the 2.4ghz band. My searching and reading stackoverflow posts suggest this just isn’t possible, but surely that’s not true?! It seems like a simple enough option to have!

Tldr : how to force my phone to connect on 2.4hgz WiFi rather than 5ghz

    The Ghz shouldn’t make a difference, so long as it’s on the same network. The spectrum used is the physical medium, a device on the WiFi and wired networks of the same network can talk to each other. Different AP may (should) be on separate channels within the given spectrum to avoid signal overlap, but still work the same.

    Why would you have to specify what frequency it’s on? The only thing the phone would need to replicate to the device is the network ID and key.
