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
If you’re using Tuya devices and your network is dual band (same SSID for 2.4ghz and 5ghz), it’ll work just fine without needing to change frequencies. I have a couple of very old Tuya lamps that I connected just like that
