@David-TP 

Thanks for the feedback. I have tried that as well.

the setup is

Internet <----> Fibre ONT <----> Deco S7 #1 in Router mode <----> Deco S2 #2

<----> = ethernet cable backhaul

No additional wifi routers in the picture.

At this point I have tried so many options that I have kind of lost track, so I have reset the wifi config on the phone completely and started from scratch.

So I have:

- Phone updated to latest android version

- Phone connected to standard wifi SSID on Deco (2.4GHz and 5GHz)

- Guest network not configured on phone

- Static IP on phone

- Phone wifi using phone MAC, not random MAC

- Phone DNS configured to Google DNS (8.8.8.8 / 8.8.4.4)

- Beamforming disabled

- Fast Roaming disabled

- Mesh wifi ENabled for phone on Deco

- Phone set to High Priority on Deco

- Reserved IP for phone on Deco - same as static IP in wifi config

I have tested that the phone switches over between Deco's when moving around without dropping internet connection.

I also confirmed that the phone switches from 5GHz to 2.4GHz on the main Deco when I move to the edge of the range - also without dropping internet connection.

I'll keep monitoring over the next few days and update.

If you have any other suggestions / questions in the meantime, please let me know

Thanks

Jacques

  Any advice?

At this point it looks like the S7's will have to go back.
