This has been reported a number of times over the years, not specifically for TP Link Deco but WiFi in general.

 

In short the controller uses bluetooth to connect to the console, bluetooth uses the same frequency range as WiFi (2.4ghz) and that can cause issues, its rare but it does.   Without going into too much detail here, the WiFi signal has a mechanism to deal with this issue and it wont massively affect it to the point it wont work, but yes its there.

 

Add to the issue the fact that 2.4ghz is massively congested already, then its only going to get worse.

 

You could try running the network optimiser and see if a channel change helps, that might sort it!   Otherwise to be honest, thats why 5ghz is the standard now, moving devices to 5ghz will avoid this issue.

Thanks for the input. I also tred disabling the 2.4 band from my main deco but problem still persist. I will try placing my deco further and see if it helps.
