Deco has temporarily switched your Wi-FI channel width to 80 MHz due to detected radar signals.
Few times in a week I have been experiencing this problem on my XE75 Pro , See below screen shot.
The XE75 pro has the 160 MHz feature which allows high bandwith speeds but downgrades when it detects radar signals. When the deco switches back to 80 MHz its pretty much disconnects all 2.4 Ghz devices, Sky Q , Ring Doorbell and chimes and most of the smart lights etc. They may come back but can be 15-20 minutes later.
On some occasions the Loft Satelite node which generally has strong wireless backhaul and very good speeds goes offline does not reconnect to the Main deco and needs to be power cycled. ( yellow or red light ) .
The XE75 will not go back to the 160 MHz wifi setting unless you manually do so in the app even though the message says " Temporarily" . I believe this DFS strike is false or not accurate as i am not near any airports or a weather station/ radar based in the UK England .
If i cannot use the 160htz my bandwith speeds are generally much slower.
Why do my 2.4 Ghz devices seem to disconnect and struggle to reconnect when this happens and does the system eventually go back to 160 Mhz or does it not work.

@IntrovertSins you might want to check that you are getting 160Mhz.
The ASUS does have an option to select 160Mhz and another to allow DFS channels.
But if you enable using DFS channels and radar is detected or if it's disabled and there aren't 8 contiguous channels it will silently drop to 80Mhz.
That's becuase, like the TP Link device, it must comply with wireless regulator requirements in the given region.
There may be a bug with the TP Link devices detecting radar signals, I don't know ...

This is the dumbest least useful terrible feature. I have problems on most Zoom calls now and it's always this incredibly stupid feature I can't turn off.
Makes the Deco system utterly annoying for day to day work. If you live in an urban environment, there is radar everywhere.

And wow, I am now on with tp-link support and the (supposedly) live agent is asking me to send him a video of my using their app to switch 80 to 160 mhz

@OriginalLimey Because they don't believe you that it does this?

How is it more than a year and this issue isn't fixed?
It happens ALL THE TIME.
If I could return this garbage, I would... in fact, I may push the reseller to take it back.
By the way... has anybody else noticed that the speed test is BS? It's a test between the modem and the router only. My internet was degraded to 500mbps and the Deco was still showing 2.25Gbps up and down.
