Hi, I just replaced Unifi router with 3 units Deco X50 (as router mode). Existing I had 5 Tapo camera and 1 NVR (Tp-link).

Initially I setup main Wi-Fi but camera are not working fine (including like air cond Wifi control). This could due to Dual band. I found no way to split 2.4 GHz and 5 Ghz. I previously helped my family member house to setup Deco X20 that can broadcast 2.4 GHz and 5 GHz, no issue.

No go.

Then I create Guest network with broadcast 2.4 GHz only and connect camera. But issue with NVR on Ethernet cable is on Main network and it can't communicate with Guest network devices by Deco design. As I read, unless to change Deco as AP mode (which I need another router) then it allow for Local Access for Main and Guest network devices to communicate.

No go.

Then I found IoT settings. Setup only broadcast 2.4 GHz and cameras all connected with Strong signal. But the network keep disconnecting, lagging or camera just went offline. Had tried to change settings on Deco for camera such as disable Mesh, Preferred Deco, Preferred Wi-Fi band, on Deco Advanced settings, enable/disable Fast Roaming, Beamforming, but no improvement.

Before with Unifi router, even camera is on 1 or 2 signal strength, it still perform so much better than with Deco. It can view live footage with just minimum delay. With Deco, live footage if it load successful with luck, it will run for few seconds and stop, then skipped 10-20 seconds and continue like this.

Is this something can be fix or any other settings that I missed out? Really seeking for help.

Thank you
