Music Library Not Doing Its One Job

Trying to play music from Library.

Song will play about five seconds - through some, not all, of the selected speakers. Then it will skip to the next and do the same. Sometimes for four songs, sometimes for five.

Then it will stop and return one of two messages:

Unable to find file (and provide an address that is absolutely findable on all other networked devices)
WiFi connection “unstable”

I spent about a grand last October upgrading every part of my network to avoid this problem, and it has returned.

I am playing the files through a Synology NAS DiskStation, that is wired into my router.

I have a Play 3 wired into my router, and in the same room - with direct line of sight, less than twelve feet away - another Play 3 and a Connect. I have four Play 1’s scattered throughout my one bedroom, 1300 square foot apartment. WiFi “instability” is not a correct diagnosis.

Yes I have changed channels of both router and Sonos. Router is on 4, Sonos on 11. Both are mega-green-starred channels on my WiFi analyzer. (1 is not as good).

Music Library is updated. Firmware on router and NAS is updated.

I have typed this while sitting on hold with support, and it is still a 15 minute hold time and I am late for another call.

@Wits’ end.

Any suggestions, other than setting on hold for a tech?

No mention of reserved IP addresses, and this sounds awfully like a duplicate IP address conflict. We tend to group that under wifi interference , although strictly speaking, it’s merely a network issue, and not specific to Wi-Fi networks.

But, since users don’t have access to that diagnostic, you may want to call in.

Each Play unit has an assigned IP.

At least it did.

Checking now…

Yeah, looking at my router, each Sonos device has:

Static address
Unique address
Shows it’s connected via LAN (and not 5G or 2G, like the TV, printer, this PC, etc...)

Even if that was the case, why would that impact only the Music Library and not any of the other services?

(Which, I did not mention in the OP, seem to be OK. TuneIn is 100% OK, the Connect has been (knock wood) stable, and the Sirius has been stable for the past few days.)

Does the NAS drive also have a reserved IP address? If the drive was being forced off and reconnecting, that would certainly cause this behavior too. What did Sonos Support say when they looked at your diagnostic?

I couldn’t wait on hold with Support long enough.

Not sure about whether or not the drive is static (not home now). Will check this evening.

f the drive was being forced off and reconnecting, that would certainly cause this behavior too.

Implying that the NAS is cycling in and out of network while the Sonos is trying to play those files? That seems… odd, doesn’t it?

I never have trouble connecting to it via Windows Explorer, which I know is different, but remains stable.

What’s the channel width on the router? If it’s 40MHz it could be interfering badly with Sonos.

Airgetlam

That’s exactly the behavior I’d expect to see with a duplicate IP address conflict with the NAS. But without you taking the time to check with Sonos, we are stuck making guesses.

Windows explorer also wouldn’t be going through SMB like Sonos does, but connecting in a completely different manner…although that might be a better explanation as to why it isn’t in fact a duplicate IP address concern.

It would actually, which is why Windows 10/11 boxes stopped talking to SMB1 shares when Microsoft disabled SMB1 by default.

Not certain I understand the question. What am I checking?

The bandwidth of the 2.4GHz channel. It it’s not stated in MHz it might be of the form “up to X Mbps”.

I once had an intermittent issue with my NAS. It was an old unit and I just assumed that it was EOL, but the issue was not fully consistent with “defective NAS”. I’m too smart to be harpooned by a duplicate IP address, right? Finally, I swallowed by pride and checked for duplicate IP addresses … darn …!! A few weeks prior I had replaced the router and reconfigured my DHCP range slightly. Of course, I reserved everything … except … a forgotten, small, seldom used palm sized gadget hidden in a cabinet. This device used a fixed IP address that was now inside the DHCP range -- using the NAS’s IP address.
