i am using a router which broadcast both 2.4ghz and 5ghz band using single SSID. how do i force my phone to only allow to connect to the 5Ghz wifi network. i cannot turn off the 2.4ghz band as there are other devices in my house that only support 2.4ghz or do i want to split the bands into 2 SSID.
This is what i did .
(It might give you an very easy option /idea .)
My current setup is a Nokia fibre router that has 2.4 ghz and 5 ghz bands
I bought a reasonable priced wifi mesh 'TP DECO M4 "then
connected it to my fibre router ( ethernet cable )
The TP wifi mesh comes with an Android app fo configure it (settings )
All i did was swicth off the 2.4 ghz band in app, for my TP decom 4 model .
So if i wand to use only 5ghz i connect to my TP DecoM4 ( which is connected to my Nokia fibre router)
My othe devices( that only use 2.4 ghz bands ) i connect dirrectly to my Nokia fibre router, that has 2.4ghz band active ...and also the 5ghz ,
So fo me its a matter of to switch 2.4 ghz on and off in the Android TPlink app .
Hope this give you an very straightforward option ?
