Shortly after setting up this router the 2.4 band went out, then came on and then disappeared forever. Reset router, looked at all settings, nothing. I have many devices that don't work with 5G, so I need 2.4G. Then I saw that other commenters had the same problem and sent it back. It looks like they really need to sort this out. Also, the phone app didn't sync properly with the router when it came to parental controls, rendering it unusable unless it was on a desktop.
