Parameters for the WiFi access point

I find this function useful as I am generally close to my mecool K1pro box.
I would like to be able to choose the band and channel it uses.
My ADSL router is far away and limited to 2.4 GHz so difficult to use.
On Android there seems to be the same function it would be nice if the parameters were the same.

In fact I was too optimistic I have not been able to use the access point at all on my K1pro
running coreelec.
