I have a pair of Deco PX50's providing my home WiFi from a 250mbs Virgin Media connection.

The satellite PX50 is in my sons bedroom and is using powerline backhaul ( strong ) with WiFi backup.

The whole setup works pretty well with very good coverage and speeds.  We have a variety of mainly Apple devices ( oldest is original Homepod ) and Tapo cameras ( approx a year old ).

After the Deco app update today however I noticed an exclamation mark (!) against the satellite.  It may have been there before and I hadn't noticed it though.

Pressing the exclamation (!) produces and strange explanation and recommendation.

This is is after I had a similar message earlier regarding the 160MHz channel width ( which seems enabled by default ) not being supported by some devices and which I changed to 80MHz at the suggestion of the prompt.  It's now set to 80 as I have only 3 devices that supports 160 ( M4 MacBook Airs ) plus I've read that 160MHz is as blessed as it is cursed for coverage and interference.

Can anyone tell me whats going on?  Is it an app bug? What on earth is 0 channel width?  Should I just leave it set to 80MHz, which seems fine, and forget about it.

Any help appreciated.
