Phone Wifi Switches ghz w/R7000

[timstack]

I'm using 2 separate names for 2.4ghz & 5ghz. When I leave the house my galaxy s8+ is using the 5ghz band but when I return it's using 2.4ghz band with my R7000. Can someone tell me why? Using. 88 version. Thanks

You've saved both names to  your phone.

2.4ghz broadcasts further than 5ghz. So its the first signal it picks up.

Can I make.my phone only use the 5ghz wifi? Or is there a setting in R7000?

Some android devices have the option to prefer 5ghz signals. Or you can just go in and forget the ssid for the 2.4ghz network.

It is usually your phone that decides which wifi source to use.
