Hi, looking for some help.

One of my slave Deco X20 keeps losing connection (flashing red). I believe this is because it keeps trying to connect to the main deco which is quite far away and through some walls. Signal source suggests it connects to the main. There is another slave Deco in the middle, clearly with a decent line of sight (especially after I moved it after developing this issue). It is obvious it needs to daisy chain but it won't. I think it has done previously.

Any help on forcing it to daisy chain rather than keep losing signal?

Many thanks for any help.
