Hey  @xunilhr,

I would first recommend trying to configure these devices using your IoT network, as there aren't as many advanced features on the IoT network, you can choose only the 2.4Ghz band, and you can lessen the security without worrying about your other devices. As an FYI, the invalid password error is thrown for multiple reasons,s, usually having something to do with the wireless security standard being used, for this reason, you should try using WPA/WPA2 on your IoT network settings.

When you moved networks, did you happen to choose the same network name and password as before? If so, you may need to reset these devices so that they are not trying to refresh their existing settings. 

I would also recommend disabling the Mesh Technology option from within the Deco app.

Sonos: What problems occur, is another error thrown? Decos are backward compatible, with the 2.4 GHz network being: IEEE 802.11b/g/n/ax, so they should work fine; however I have seen users purchase a bridge/hub from Sonos to help improve performance with new networks.

Hey @Amberglow,

There are a few things that you can try to help mitigate or ease the transitions beyond what I mentioned above; however, much of it is dependent on the device settings and capabilities.

First off, disable Private Addressing on your iPhone. This will allow your router to better manage and shift the connection of your phone. It is possible that this feature is being triggered either while roaming between nodes or when changing between 2.4 and 5GHz. This would also cause you to receive a completely new IP and a lapse in connection.

Next, I usually point towards the Beamforming and Mesh Technology options available in the Deco app for the device. These are the technologies from recent Wi-Fi iterations that are most likely to cause disconnects when the client device does not also support the feature.

For the devices that seem to lose their IP or have to reconnect often, I would recommend taking a look at setting an IP reservation for the device, as this can help remedy a few situations where devices may fight for an address.

Do you have an example of some of the Wi-Fi devices/cameras you are seeing disconnect? Without additional details, a very wide net would need to be cast in order to troubleshoot and identify the cause.
