i realy missed the feature that let us choose the prefered wifi band / frequency on android 7.0 and dont know why they removed this from wifi advanced settings. Why? because sometimes when im outside and using a public wifi that have the same ssid beetwen 2.4 and 5ghz channel so i cant choose manually.
So heres how i did it manually using root explorer,
first go to system/vendor/etc/wifi/ and then open WCNSS_qcom_cfg.ini with text editor
scroll down untill you find this line:
#Preferred band (both or 2.4 only or 5 only)
BandCapability=0
change it to:
BandCapability=2
0 = auto, 1 = 2.4ghz only, 2 = 5ghz only.
this should be working on all device running oreo or pie. but do it with your own risk and always backup the original file first! :fingers-crossed:
