Router band toggle

I hope this is where I'm suppose to put this.

I want a widget/script (prefer gui with 3 way toggle) 2.4 GHz / 5 GHz

one or the other on or both.

This is not for the computer it's for the router (i'm just too lazy to go in and switch between them all the time).

Applicable sense, headphones run on 2.4 signal and are within range to be interfered with by components connected to gateway. Main computer is hardwired and will nix 2.4 when the headset is in use and bring it back when done (via tool). Secondary computer cannot re-connect if switched off network unless wired / 2.4 is reactivated (probably another work around but didn't think about that till now.) Furthermore possible setting it up to where script is ran once mumble or similar is launched but I'd rather just have a simple taskbar or desktop widget. Thank you
