Since mine don’t drop 30 seconds into any song, or, frankly, at any time, I’m going to assume you may have a local network issue, which Sonos requires in order to maintain a connection to play. Have you called Sonos Support directly to discuss it? What did they say?

Unfortunately, I have several Sonos products….  I’ve contacted them many times.  I once, just once, talked with a gentleman that spoke English and was able to problem solve my ARC.  It is such a shame!  Incredible speakers!  They just don’t work.  

​@Airgetlam As your setup seems to be fine, may I ask

a) Are you running a mesh network or just a single no-frills access point with good coverage? 

b) Do you have wifi6(or 7) enabled, or have you restricted the network to just wifi5? 

I have a single wifi5 access point with excellent signal strength and latency (+static ip’s for all Sonos devices), and eventually I’ll have to upgrade to the new app+firmware.  Currently trying to figure out if my very simple old school network would shield me from the potential problems some users are dealing with

Here are some network guidelines from Sonos:

Can you describe your network?

Do you have any of the unsupported devices in your network?

I have used Sonos since the ZonePlayer days and the only time I had a connection issue is when I attempted to use a set of powerline adapters. Once I removed them my system worked as it should.

In answer to the questions from ​@fforssell 

1. a no frills single point router supplied by T-Mobile.
2. No, as far as I’m aware, this router is only capable for WiFi 4, although as far as I’m aware, ‘greater’ versions of WiFi are fully compatible with WiFi 4 devices like Sonos. 

I’m delighted they were able to solve your concerns with your Arc. 

And I’d certainly encourage you to update to the latest firmware and controller, Sonos has made significant strides in recent months in adding back in features, although none of the ones I used were removed, which is mostly playing my playlists from an NAS, and using iHeart radio, with occasional lapses of other streaming services. It’s super hard for anyone, Sonos or not, to provide assistance for ‘outdated’ systems, since access to them, and consequently knowledge about them, is fairly rare. 
 

​@Rhurley437777 , every single time I’ve called in to Sonos (several), I’ve ended up speaking with an individual who was able to assist me. Having worked with and called my fair share of ‘assist lines’, I’m certainly aware that sometimes, my knowledge is greater than the person I’m speaking with. I’ve never been shy about hanging up, and trying to call in again, to get someone else…but I’ve never needed to do that with Sonos. I’d certainly encourage you to try again, they have access to lots of data, as well as tools, that we in the public don’t. 

However, there are lots of folks in the public who have great knowledge that they’re willing to share. Answering questions such as ​@Pools-3015 have asked would go a ways in building a mental image of your network and Sonos system, and perhaps get to the issue you’re currently experiencing. Unfortunately, right now, the most we know is basically ‘I’m unhappy’.

Is your wifi locked to a single channel, or does it “Auto” hop between channels? Locking it to one of channels 1, 6 or 11 is best. If you’re using SonosNet put it on one of the other of those three channels. Historically, it has also helped if you set an allocated ip address to your Sonos devices too; doing so will do no harm. 

​@Airgetlam Thx for your input!  Totally aware of the backwards compatibility, but my first Wifi 6 capable router didn’t play nicely with Sonos until disabling Wifi 6, for some odd and unexplained reason. Ever since I’ve kept things that way, as WiFi 6 isn’t essential for my domestic use

That certainly suggests an issue in the router’s firmware, and not in Sonos itself…

Absolutely a router issue, this site is full of Asus/Sonos debugging threads - not too happy a relationship, it seems
