Hello, I use Xiaomi Mini for repeater, is there any way to make it broadcast wifi to 2 bands running dual band (if only emitting 5ghz, the signal is very strong and can be used normally, but if i turn on 2.4ghz with the same SSID name as 5ghz, my phone can't connect, do you change the SSID 2.4ghz name to be difference, sometimes it's worked, sometimes it's not). Help me bros
