Different WiFi Frequencies, Same AppleID - How to split?

I am curious, is this because they are tied to the same AppleID?

Not that I can duplicate.

If you want the iPhone to connect at 2.4 GHz and the iPad to connect at 5 GHz, the only way to try to make this happen is assign a different Wi-Fi network name to each of the 2.4 GHz and 5 GHz signals.

Your Wi-Fi router may or may not offer this option.

Then, "aim" the iPhone at the 2.4 GHz network name and the iPad at the 5 GHz network name.

On the iPhone......

Tap Settings > Wi-Fi > Edit (in the upper right corner)

Is there a listing there for the 5 GHz SSID? If yes, you need to tap on the "blue i" to select that network and delete it.

In other words, the only listing there should be for the 2.4 GHz SSID
