Model: Deco S4  
Hardware Version: V2
Firmware Version: 1.6.2

I have a mesh of S4 units (3 of them) and one M3W unit with the main (S4) unit configured as the router connected directly to the NTE.  I have 500Mb/s broadband from plusnet.  When connected wired to the main unit I get 500Mb/s (or very close).  On wifi connected to the main unit (from an iphone 11) I get roughly 350Mb/s but as soon as I connect to any other unit it drops to around 50Mb/s.  According to the app "Everything looks good".  Any idea why the wifi speeds are so slow on all the satelite units?  Also, when I look through the web UI at the cpu load it always shows 100%.  Not sure if this is related.

Hi, Thank you very much for your time and patience.

Did the issue start recently?

 

Are you able to connect the satellite S4 units via Ethernet cables to the Mesh system?

For pure WiFi Backhaul, due to the working pattern and protocol/regulation of Wi-Fi technology, the more wireless hops, the slower the speed would be. So it is hard for the satellite Deco to maintain a decent speed.

For more details, please refer to:Why is my satellite Deco unit not getting the same speed as the main Deco?

 

It is also suggested to unplug the Deco M3W first, then install the beta firmware here which could help customize the signal source of the satellite Deco S4.

Thanks again and best regards.
