So frustrating.  All wi fi analyser apps i have downloaded are confirming that the wifi channels that my Deco is using are the weakest (channels 48 for 2.4 ghz and channel 9 for 5ghz). This has never changed despite rebooting a couple of times.

When i add a guest wifi fi it chooses the same (poor) channels.  My wifi is dropping in and out regularly.

It seems farcical.  Please help.  Are  my devices (3 decos) faulty?
