OFDM ANI level 9 everywhere in the house

Have you tried disabling Airtime Fairness for both 2.4 and 5GHz bands on your router?

Yes, sorry - I should have mentioned that.  AirTime Fairness is completely disabled and Qos is turned off.

I should also mention, that I’m able to plug one of the Play 1’s in the office into an Ethernet cable.  From the network matrix, the connections using that Play 1 seem to be green, but the drop outs still occur and all of the speakers show red.

Up until a few months ago, everything seemed to work fine.  Sometimes the music will play for hours uninterrupted, and other times I’m lucky if it last five minutes.

Thanks again.  I appreciate it!

Have you tried changing the SonosNet Channel in the Sonos app under the Network settings?

Is there any difference if you keep the Play:1 wired but disconnect the Boost completely? Or keep the Play:1 wireless and just use the Boost?

You mentioned “during the day”, does the situation improve at other hours? How are your noise floors? Does your WiFi analyzer show channel width? You may have a neighbor who is using wide channels.

EoP (Ethernet over Powerline) is my absolute last choice for networking, but sometimes it is the magic bullet. While it is immune to WiFi trash, power line trash can be a problem. If you try EoP, don’t plug the units into high end surge suppressors and try to avoid sharing an outlet with a surge suppressor. Large appliances on the same circuit can be an issue. Your electrical panel is arranged in columns. Outlets in the same column work best. If you have multiple panels, EoP does not travel well between panels. The newest EoP units are superior to older units. It’s counterproductive to get a “deal” on an older unit.

I had changed my 2.4ghz channel on the router to 20mhz and set it to channel 1.  I set the SonosNet channel to 11 in the app.

It doesn’t seem to make any difference whether the boost is plugged in or the Play 1.  I only have until Friday to return the boost, so I wanted to make sure it wasn’t going to help me out.  I did plug the boost into ethernet in a different part of the house, and nothing seemed to even use it judging by the network matrix.

I did realize something a little bit ago.  Even if I just play music on only the Move (connected to 5ghz), it too stops after a few minutes.  Not even grouped with any other speakers.  Not sure what that might be an indication of.

Thanks again.

What is the source of your music?

Are the PING times to your network clients reasonable?

The ping times seems to be pretty good to all devices.  Usually around 1-3ms.  The music source is typically SiriusXM.

Good question about day versus evening.  I don’t tend to listen as much in the evening so I can’t really compare.  I’ll have to do some testing.

Currently I’m just using the free Wifi Analyzer app from the Windows store.  I was doing some research on some others, but haven’t figured out exactly how to read the data very well yet.  I’ll look into that some more this evening.

I should mention that I have AT&T Uverse cable and currently both the gateway and the ASUS systems are doing NAT, so I’m in a double NAT situation if that makes any difference.  None of that has changed anytime recently.

I appreciate your help on this!

Double NAT will inflame the hard core network types, but it’s not the end of the world -- unless you are attempting remote access, VPN, etc., then it gets a bit messy. But, you’d already be having issues. If possible, disable the Uverse’s WiFi because this is just clutter.

I use Android devices to host my WiFi analyzers. Apple phone/pads are not as useful because Apple does not make much data available to the API. I have no experience with Windows analyzers.

Your PING times are fine. Tons of dropped packets are not.

I’m sure that you are already aware of this, but just to make sure -- the Network Matrix is a static view, refresh the page for an update.

ZigBee devices can cause WiFi interference.

In an attempt to avoid being blindsided, have you recently tried other music sources?

Thanks Buzz.  The wifi is disabled on the ATT gateway since it’s not being used.  I think all of my smart home devices are Zwave, but I’ll double check and make sure some ZigBee stuff didn’t make it’s way in there.

A different music source is a good idea.  Let me give that a shot tomorrow to see what happens.

Am I correct for assuming that since the Move stops playing the music when it’s not grouped with other speakers, than maybe the 2.4ghz interference isn’t my issue?  The Move is definitely connecting to the 5ghz band and has a great connection to the mesh node.

Thank you!

Don’t assume that the interference is limited to one band.

Are you using the SONOS App to play music? If you are having dropouts to the not Grouped wired unit, I’d be suspicious about something fundamental in the network. Is the wired unit wired to the router or a wireless mesh node?

People have been reporting issues with other ASUS routers. Various “Solutions” have been reported. Full disclosure: I don’t have any direct experience with any recent ASUS routers. Some users report that turning OFF Airtime Fairness is the magic, others report that rolling back the software is the answer, and recently some have claimed that the latest ASUS firmware is magic -- but only if the router is factory reset after the update.

Of course, router updates are not likely to cure ANI level 9 issues,
