@JMJFDUDE,

Normally behaviors like this are a result of one of a few features that you can disable in the Deco App: Mesh Technology, Fast Roaming, and Beamforming.

In this situation, I normally recommend setting an IP Reservation for the devices in the Deco App, along with with potentially configuring a connection preference for stationary devices. If the devices are connecting once per day, it could be possible that the devices are simply failing to get a new IP address at refresh.

Lastly, if the devices are older, you may consider adding them to your IoT network, where you can set either a lower security method that may be more compatible with your network card, or set the network to only use the 2.4Ghz network.
