OFDM ANI level 9 everywhere in the house

I started having problems with audio randomly stopping during the day a couple months ago. I only recently learned about the Network Matrix so I have no idea what it looked like before this started.

I currently have two Play 1’s in each upstairs offce, a Play 5 gen 2 in the living room and an Move in the Kitchen. When I look at my Network Matrix, both Play 1's and the Play 5 are all showing OFDM ANI level 9. I have a few home automation devices that are stuck using 2.4ghz, so I figured it might be interference from those.

I’ve pretty much turned off every device in my house, moved the speakers everywhere I can think of and nothing seems to have made any difference. I replaced my mesh wifi system with an Asus AX6600 and bought a boost to try. Same thing. All of the speakers are red, as well as the boost.

I do live in an are with some wifi congestion, but I find it hard to believe that there would be that much interference from my neighbors that it causes the OFDM ANI Level 9 no matter where in my house I place speaker.

I’ve tried making the suggested changes to the 2.4ghz channel on my router. No difference there as well. I have tried using a wifi analyzer app, but networking and wireless are not my expertise.

Short of flipping breakers in the house, I’m kind of at a loss as what to try next. Any suggestions?

Thank you!

I did quite a bit of searching before posting so I read about the ASUS related issues. I’ve tried all of those changes and none of those made much of a difference.

I should mention as well, that the speakers were all in a WIFI configuration (No SonosNet) for quite a while without issue until the drop outs began a couple months ago. At that point I was on a first Gen Google Wifi setup that had been giving me other wireless issues as well. That’s when I decided to upgrade to the ASUS setup. I was getting the same ANI level 9 on the speakers when I was using the Google Wifi.

The hardwired Play 1 is plugged directly into the secondary node, but it’s connected to the main node via ethernet backhaul.

I really appreciate the help. I’ll keep digging. I’m still just hoping that interference source is something within my house since it happens anywhere I place the speakers. If it’s something from my neighbors, I’m not likely to get them to change anything. Maybe I can get them to move? :)

You may be familiar with the ancient BSR X-10 system. It is not at all secure and there can be accidental interference between neighbors. A magazine article reported the scheme used by a fellow who had a very elaborate system using dozens of dimmers to create sunrise and sunset lighting. A neighbor was duplicating some of the codes and disrupting the show. Our enterprising fellow set his computer to loop through the whole control space giving miscellaneous commands. Eventually the neighbor gave up attempting to use this “unreliable” system.

While walking your space using a phone/pad based WiFi scanner you may be able to get a sense of the interference origin.

I appreciate your issue because I can have mostly red cells in the left column of my matrix. There is a medical facility next door and various “high tech” nearby homes with unfortunate WiFi channel assignments. I’m still testing. Currently, my SONOS is WiFi.

I wanted to update you, buzz. I’ve been playing Apple Music the last two days and it’s been solid for 8+ hours each day. No drop outs at all.

I’ll probably continue to see if I can pinpoint the source of the interference. More for my own curiosity than anything else.

I’m a little disappointed that SiriusXM seems to be the issue as there are a few stations that I enjoy listening to. I did some brief research and there are others that have a similar problem. I’ll probably dig into that and see if I can come up with anything.

Thanks again for all the suggestions!
