split frequencies unable to connect 2.4 for all smart kits

[papagray1706]

i have many smart items on the 2.4 ghz frequency , alas the newer hubs have combined frequencies of 2.4 and 5 ghz locked to gether unseperable the 5 being the stronger often blocks the 2.4 so i need to be able to have a 5ghz wifi and a 2.4 ghz seperate while i enroll them once enrolled they will communicate one returned to the combined i would like to know which sky broadband allows this i have fibre to the home i am quitting one company as they are unable (or unwilling) to write three lines of code to the firmware to enable the frequencies be split for enrolling purpose so does sky fibre have the ability to split the frequency so 2.4 is standalone ????

@papagray1706  Take it that your broadband is white in colour and not black, is this correct?
