I'm having the same issue after they did a firmware update.

They should really look into this.

I have (2) nodes and yes each one has the same issue. It happens when I am directly in front of each node. It is frustrating.

I have tested my internet speed and am getting the speeds designated by my internet company, but my cellphone is only showing 1-2 bars... even when I am directly in front of one of the nodes. What can I do to fix this? I am constantly optimizing, but it does not resolve or improve the situation.

@RobynRAZ   I just replaced my Google Mesh Wi-Fi because the individual routers are failing with the Deco X20 three pack. I am vary disappointed with the coverage as three X20 provid poorer coverage compaired to the old Google pucks.  My wired destop PC speeds are the same, but there is a very noticeable drop with my cellphone and with smart switches/outlets due to the drop in signal.  I had r eally hoped the hype was reality but unless someone can come up with a magic fix trhey are going back to amazon.
