If your referring to 2.4Ghz and the 5Ghz wifi bands then you need to open your routers setting and disable the auto (band connection) feature.
On my netgear nighthawk its called 'smart connect' (in the WiFi settings section) or something along those lines (It lets the router decide which band to put your device in), Disabling this will essentially give you two wifi access points that will be joinable. The 2.4Ghz band and the 5 along with two access point names.
You will need to make sure you set passwords for both points. This will allow you to choose which wifi band you want to join.
There is also lots of evidence showing 5Ghz is capable of faster transfer speeds, Running a speed test whilst conncted to each one will show this (providing you have speeds well over 300MB/s available to test).
As a rule of thumb 2.4Ghz has slower max speeds but cover a greater distance in signal and 5Ghz works the opposite way round (more speed less distance).
Anyway sorry for the long winded reply. If I understood your post correctly.. The setting your looking for is within your router settings.
Done and done no difference and that's the least of my concerns caused by this insane update including my details being leaked onto the net to me by Sansung themselves via a push notification they had discovered less than 2 days after having to give then All my devices codes given then tottal access to fix mirror funny how I can instantly cast from thecsane phone the sameTV when I use utube casting via pressing a single button
And that's fibre test I I'm using the 38mMbytes per second which is the system your talking of and tt have told me is enough with plenty to spare it's their latest 4k router sentvthrough their latest 4k smartbox which allows ne to use both phone and TV to stream view and download or and a third system
She wast talking to you by the way shouldn't you be at Sansungs office by now busily designing yet another Android update that ruins your customer's lives !
