What would cause ALL my WifI points to have a weak connection?

[drrmjones]

I have one Nest WiFi Pro router and four Nest WiFi Pro points.

For weeks, the mesh test has reported three of the points with a "great" connection and one with a "good" connection.

However, starting a couple of days ago, the mesh test consistently reported that ALL FOUR points had a "weak" connection. I ran this test several times over the past couple of days.

So this morning as an experiment, I used the Google Home app to restart one of the points. Then I did a mesh test again and, sure enough, the restarted point reports a "great" connection again, but the other three still showed as "weak". 

So I individually restarted each of the other three points and did another mesh test  I am now back to normal, with three "great" connections and one "good" connection.

So I have apparently solved the problem for now, and we'll see if it happens again. But my question is this: What on earth would cause this to happen?

Isn't it suspicious that ALL the points turned "weak" at the same time, and that the problem was fixed by restarting them? This smells like a software bug to me. What is going on? What would cause this to happen?

@Kurelgyer at this point I'm considering switching myself. Which brand did you switch to, if I may ask?

Hello everyone,

Just one quick final check in here since activity has slowed down. We'll be locking the thread in the next 24 hours, but if you still need help, I would be happy to keep it open. If there's more we can do, just let me know.

Please dont lock this thread!!!   I have had this issue several times now and dont believe it has been permanently resolved.  We need this thread kept open so we have continuity and get this issue which is a major problem for us resolved.

I've actually been hit with a similar performance drop recently where connections that have been great in the past have suddenly become intermittent and are weak. @Kurelgyer how are the Deco's doing thus far? I'm thinking about cutting my losses, recycling my Nest Wifi Pro's, and going to tplink.

Hi all, i have starting having the same issue since last google home app sw version on IOS done last week. It only work well for a few hours after a factory reset on the wifi router. This is very annoying and i hope Google can cover this asap.
