Changing Samsung connect home WiFi channel?

I had recently experiment very low transfer rates and inestability on my samsung connect home mesh network, which is my smartthings hub too. It seems a problem With WiFi channel that has a default and only possible setting of channel 5 for 2.4Ghz WiFi.

This problem makes me to reconsider to buy another mesh network solution and to disable WiFi on my connect home routers, but it seems too simple to just change the channel, as with every other router could.

Is this a hardware imposibility? Or just a forgoten feature? Can I change the channel through an advanced hidden setting? Or there could be an option on

Thank you
