OFDM ANI level – Red (9) to Green (0)

Hello Everyone, I used a Boost (wired to the Router) to create the Sonos Mesh (SonosNet) for (4) Play 1 devices all wireless. Looking at the Sonos Network Matrix, each Play 1 including the Boost showed OFDM ANI levels of 8-9 with each column box fire engine red. I removed the Boost (unpowered), unplugged each Play 1 and then powered them back up eliminating the Sonos Mesh. My Router showed that each Play 1 connected to the 5 ghz Band on my Network. Looking at the Sonos Network Matrix again, OFDM ANI levels dropped to zero and each column box green as grass. My question is, did I effectively take care of my noise level issue or is the Matrix unable to detect/record OFDM ANI levels when devices are connected to WiFi?

Thank you Buzz, but here in Canada we are very courteous and polite in Parliament 😎 no chaos concerns …. Ken, thanks for the link, I did read that article on mesh although I found the wording a little confusing but I got the gist. My cable company Modem has a built in Router which I had disabled immediately so Orbi is the only Router with fixed channels. I set IP reservations for every Sonos device (all 26 of them) and all other hard wired products (NAS, Xbox, etc). Only a handful of devices (phones, tablets) grab from the IP pool.

@bac-canada Except for the red levels in the Sonos network matrix do you have any problems with your set up?

The issues are (hopefully were on new setup) only with the (4) Play 1 devices upstairs because everything else is hardwired. The upstairs Play 1 units would drop out and worse in stereo mode. Interestingly, the old standby Play 5 (actually S15 originals) performed better and less prone to noise.

This is unquestionably a networking issue not a Sonos issue.  That does not mean that there is anything faulty in the network or in @bac-canada‘s configuration of it.  The cause of the interference in the 2.4GHz spectrum may remain a mystery, but it is clearly there.  In such circumstances it is not a surprise that a setup based on wired speakers and 5GHz WiFi performs better  than a system using 2.4GHz, including SonosNet, which is not best in every situation.

If the system is now performing well, isn’t that job done?
