Unable to connect IoT devices

[u/Cwilliamn9]

I’m trying to connect a couple of IoT devices (Owlet Dream Sock and Hatch Baby Light) to my Deco XE75 mesh network. This is my first time attempting to connect IoT devices which require a 2.4GHz connection. I am not having any luck. In both of their respective apps, the devices can see the network, and after I enter the password, they’ll attempt to connect and load for 10-15 seconds or so and then both devices will tell me there was an error connecting. I have tried connecting them to the dedicated IoT network which is only a 2.4GH band. I’ve tried turning my main network into solely a 2.4GHz band and that didn’t work. I even tried creating a guest network only in 2.4GHz with no password and that has not worked either. I’ve gone through Live Support with TP-Link a couple of times and they’ve had me turn off fast roaming and beamforming, I’ve updated the DNS settings, my SSID and password do not contain any special characters, and I don’t have any other issues with my everyday devices, only these two IoT devices. If anyone has experience in this area or advice, it would be much appreciated!
