Model RBR750 Cannot connect a fan that requires a 2.4Ghz connection.

A couple things. 

1. its not the orbi that connects to the devices but the other way around. its the devices that connect to the orbi

2. Some older/poorly coded devices struggled with AX. You can try logging into the orbi and disabling AX on the 2.4ghz band and see if that'll help. (through the browser log in and click on wireless settings, uncheck enable 2.4ghz AX box)

3. before trying that though, try and get a phone/tablet connected to the 2.4ghz and try going through the setup on the fan. It shouldn't matter if you're connected to the 2.4ghz or the 5ghz but when app makers do a poor job coding, it does. So if you're phone/tablet isn't on 2.4ghz, some devices won't setup. Sometimes it can be a challenge to get the phone to be on the 2.4ghz. What I've seen done is to shut off the satellites, turn down the transmit power on the 5ghz (under advanced tab-->advanced--->wireless settings--->set the transmit powr for 5ghz down as low as it goes). Then try walking a ways away from the orbi and disconnect/reconnect your phone. This gives you a better chance of connecting to the 2.4ghz. If you do, then try setup. Once the device is setup, you should be able to turn power backup, turn satellites back on, and have it back at base settings. Once its setup, usually it just auto-reconnects.

That's it. When I set up my Orbi router it automatically connected to all my Google devices - speakers, doorbell, thermostat but not to my fan. All the Google devices had been connected as 2.4Ghz devices. They are now connected on a 5Ghz band. 

The fan requires a 2.4Ghz band and I cannot figure out how to connect it so that I can control it using a Google speaker. It worked fine when I was using the Netgear Nighthawk Model R6700.

So we can best help you, what is the exact make and model of your fan?  And how are you trying to connect it to your new Orbi:

1. Did you set the same wireless SSID and password on your Nighthawk so you expect everything to reconnect automatically?
2. Or, are you now using the fan's app or website to try and connect it manually?
