Connecting Arc Ultra to existing Sonosnet

Thank you very much for such a quick reply. So do I need to think of the Arc plus surrounds as being totally separate from everything else? If I had the Arc plugged into ethernet and also the rear One, then neither of them could provide Sonosnet.

If I go with your suggestion, presumably I will only find out if it works well enough over time depending on the stability of my surround sound. So in the meantime I need to find a way to service the rest of my Sonos speakers.

I don’t; know anything about the Boost so will investigate. I presume I just plug that into the router and that controls the network for my other Sonos speakers as my One does now.

I presume there is a technical reason why it works this way, but it’s frustrating that modern technology is never quite as easy it it sounds like it is going to be.

Sorry I should have done this before replying, but I had a look at the Boost.

Oddly enough I couldn’t find it in the Sonos shop, so not sure if it has been discontinued. But I found the user guide and it says this “: Portable Sonos products cannot connect to the dedicated wireless network created by Boost.”

I have two Roams, so it sounds like they wouldn’t work. So in that case, my only option is presumably to plug another One into the router right next to the one I am intending to use as a rear speaker?

Note the original Arc and the Arc Ultra behave differently when wired, so correct naming of devices is important here.  The original Arc will create SonosNet for other devices, the Arc Ultra will not.

The Arc Ultra and surrounds should just be considered as another room, with a different connection method to your router.

The portables, Era speakers and Arc Ultra do not utilise SonosNet. They only connect to the router’s WiFi, although you can wire the Arc Ultra directly, or use Sonos combo adapters for the Eras. Routers and mesh network have developed greatly since the introduction of SonosNet. Many users now have a fully wireless setup.

The Boost has been discontinued, that’s why I said a 2nd hand Boost as you can pick them up cheaply on eBay or equivalent.

The Roam’s aren’t using SonosNet created by your wired One.

See the following page for product compatibility with SonosNet.

Ah thank you for clearing all that up. I had always presumed that all Sonos speakers connected the same way. I had no idea that the Roam was working differently.

It’s also a surprise to learn that the old Arc may have served me better.

Anyway you have given me some good suggestions, thank you so much, I will rearrange my speakers so I have a different one plugged into the router then will try the Arc wireless and see how that goes.

If that works then I will go with the Boost - it sounds like a decent option particularly as it gives me an extra ethernet port.

Anyway, thanks so much for clearing things up for me.

I believe the Boost has a low speed Ethernet port so be aware of that when connecting to it.

I think all Sonos products have a 10/100 Ethernet port, although that may have changed on later products. The speed /bandwidth necessary for music just isn’t that great, and I suspect at the time of design/manufacturing, there was a significant cost difference. 

As I say, it might be different on newer product. As time moves on, I suspect finding older, slower ports are more expensive than the current gig speed electronics, sold at commodity prices, 

I think the fast older generation Ethernet ports drew more power, maybe a shorter maximum cable length too.

Still good enough for a lot of stuff, I have a good number still in use here. Since they have no issues negotiating a connection to a newer Ethernet switch there is no reason to replace them.

You just don't want to hang a data-hog like a NAS or HD TV off the slow link.

Good quality, metal cases and solid connectors, 5 and 8 port dumb switches are in the $20 US range.

I wouldn’t want to route data through a Sonos product. Connect everything back to a switch or router. 

Useful to know about the speed, I will bear that in mind when I choose what to use it for. I have my Philips Hue bridge connected to a random One in the house and it works pretty well so think it would be perfect for something like that.

As maybe a longer term option, would something like the Amazon eero work well with Sonos? So put everything Sonos related to wifi and then just have a couple of the boosters where needed.

If you add Sonos Boost units you are going to be running Sonosnet, not what you really want theses days in most situations. You’d have to buy them used too as they are no longer sold by Sonos.

If you are talking about adding mesh nodes for the eero then you’d be staying on your WiFi.

I just have my ISP router at the moment and the last time I tried to run my Sonos from that it was a bit of a disaster. Sonosnet is working pretty well for me these days. The thought of buying something like the Eero appeals if it will give me better wifi speed and coverage overall but I read a bit more about it and although it does sound good it also sounds like it might be quite complicated to set up, given I’m no networking expert.

Anyway I relocated another One to my sitting room and now have the Arc setup with two Ones as surrounds, all wirelessly. The trailers for Napolean sounded great, so we will see how that goes. I’m a little unclear as to why the Arc would need an ethernet connection for normal TV viewing - in that the sound source is not from the internet and it is connecting to the surrounds wirelessly anyway. Possibly if I am going to be using it in conjunction with my other Sonos speakers. I presume there is a complicated technical reason why this setup is preferred.

I ordered a Boost from ebay for £25, so that will give me options.

Anyway, thanks again for all the input. You have all been really helpful.

PITA but you really need to say Arc Ultra or just Ultra, Arc alone can get folks thinking you are talking about the original Arc and it is different enough to get you some very confusing answers.

The Ultra shouldn't need Ethernet, Wi-Fi should be good enough if you have an adequate signal.

The Boost may help you with any Sonosnet compatible device's connectivity. The internal Network Matrix web page will show you if it is being used or ignored.
