Just got a Move 2 and a Roam.

I have 2.4ghz and 5ghz  networks but both these portable units have connected to the 2.4ghz and I can't see any option to select the 5ghz. 

There is not UPDATE NETWORK button in the settings on the app. 

I have a Playbar, Sub, 4x S1's and a Beam. The Playbar and the Beam are ethernet connected.

All work well I just want to move the Roam and Move 2 to the 5ghz and can't understand what I am missing?

(Got a Boost in a drawer that I've never used so would I be better off setting that up and connecting the portables to that?)

Thanks

Mark
