Network question when using older and newer components

Not sure I fully understand, I may need some caffeine first, but here’s some data which may help…your surround speakers and Subs, which are ‘bonded’ to your soundbars actually connect to your soundbar, and not the router directly. They do receive IP addresses from the router, but connect to it through the soundbar itself. So if your soundbar is wired to the router directly with an Ethernet cable, don’t turn off its ‘radio’ as it is using it to communicate with the bonded devices.

I don’t think, in your scenario, there’s any reason why 5Ghz won’t work, but you haven’t been as clear about the status of the Beam and two Ones…are they set up as surrounds? If the Beam is wired as well, and the radio left on, it should continue to work.  I think, and it’s a fairly easy test, that the whole thing will work without issue, as long as you wire the Arc. 

Thank you for the quick reply, 

The only thing I am looking at wiring is the arc.

The beam and the ones are are in different rooms and not bonded.

I was thinking the arc would create sonosnet when wired which the ones would also use as they are components that used this,

I believe the eras and beam gen 2 will not use sonosnet.

So, will the eras continue to work as normal due to being bonded to the arc?

Will the beam need to us wifi still rather than sonosnet?

And will they all still work together? 

2.4g will be turned off on the wifi but the radios will not be turned off on the speakers.

Sorry if I am being silly or not explaining well. Ot comes from what I have read about the older arc and ones vs the newer beam and eras with regards to wifi capabilities.

I may just give it all a go and see if it works 🙂

The Arc can’t create what we call SonosNet. It only creates a 5Ghz signal for ‘bonded’ devices to connect to. so your Ones would need to connect (and should) to the router’s 5Ghz signal. As your Beam should. Since it isn’t using its 5Ghz antenna to connect to any bonded devices, that leaves it clear to connect to the router’s 5Ghz signal. And everything should still work as they always have, together, in the Sonos controller. Just be sure never to turn off the radio/wifi in your soundbars, even if they are wired. They need that capability to communicate with ‘bonded’ devices. 

As I say, this should be a fairly easy test to try. 

Not quite correct.

The Arc does create SonosNet when wired. You are possibly thinking of Arc Ultra which does not.

The Beam gen2 is only able to connect to the router over 2.4GHz or via SonosNet, so will connect through the wired Arc, as will the Ones assuming there is sufficient coverage of SonosNet to do so.

Why turn off 2.4?  It does penetrate walls better than 5.  Music streaming does not require 5.

That fits with what I have read exept i thought the beam gen 2 would not be sonosnet but would be 5Ghz, unlike the gen 1. I assume the sub gen 3 will use the Arc sonosnet.

Will the era 300s still work with the arc as they too won't do sonosnet. They are currently bonded to it though?

I can't afford to update to Arc ultra and sub gen 4 yet

The Era 300s and your Sub are bonded to the Arc. They won’t be using sonosnet.

I have some non sonos devices that can do 2.4 and 5 but always choose 2.4 and have no manual selection option. I need them to choose 5 as this workes better when using them to game over cloud, to force this i have  turned off 2.4 but this causes the arc etc not to work as it can't do 5. So looking at hardworking to use sonosnet but my never speakers won't do this. Just trying to fund out if they will all still work together  before messing with cables etc

This support page confirms the Beam gen2 can only connect over 2.4GHz.

The Sub gen3 will also connect via the wired Arc.

Does the Sonos app already know the 5GHz WiFi credentials? If not, I would attempt to add the network in the Sonos app first before wiring the Arc. The Era 300s will connect over the Arc’s 5GHz radio when they are bonded as surrounds to it. 

Thanks for the help I will give it a go 😁

Yeah.  Sometimes “Band Steering” ain’t so smart.  I have the same thing with my ISP.  So far, though, after a day or so the network figures things out OK.

You want to turn off your router's 2.4 gHz signal and replace it with a much less capable 2.4 gHz Sonosnet signal?

Wouldn't it make more sense, and work better, to set your router to deny a 2.4 gHz connection to the problem devices?

​@Stanley_4 

You can do this for individual devices?

EDIT:  Looked up how to do it with my ISP Gateway.  Have too change the SSID for 5.

You just block the MAC Address in the router’s settings for the particular band. I’ve blocked majority of my Sonos devices from accessing the  2.4GHz band.

ISP hardware is known for lack of features and bugs in the ones offered.

The fix is to get some good quality hardware, put the ISP device in bridge/transparent mode and connect the new router to it.

Splitting SSIDs has been mentioned as a problem here, I'd avoid doing that.

All the advice is appreciated. I wasn't thinking of changing any settings in the router besides turning off the 2.4ghz.

I was then going to hardwire the arc in the hopes that all my devices would use sonosnet with the arc no longer needing wifi. And hopefully the era 300s will still work as surrounds done to being bonded as they count actually use sonisnet.

Would just have been more useful if sonos had of continued with sonosnet on new speakers.

All my other devices would then use 5ghz wifi as this is the only one available.

There are two Sonosnets.

The obsolete 2.4 gHz one, very old standards and much worse than any modern Wi-Fi router.

The 5 gHz one used to connect subs and surrounds, haven't seen the specs on it.

Abandoning your 2.4 gHz home Wi-Fi for the 2.4 gHz Sonosnet just isn't a good idea for Sonos devices.

If you do activate the 2.4 gHz Sonosnet you may find other Sonosnet capable devices using it and not your Wi-Fi.  

Fixing the problem client device issue is a better option.

I'm interested in your thinking on the 5 gHz band being better for gaming.

-  Are you using a wide enough bandwidth on 5 gHz to carry more data than 2.4 gHz can?

-  What difference in latency are you seeing between the two bands?

-  Are your 5 gHz channels clean enough you are actually seeing better performance there?

I was thinking the sonosnet would be using 5ghz not 2.4 ghz. 

The gaming aspect i am talking about is in relation to cloud gaming such as geforce now and xcloud, so the whole game is streamed from a client pc over the Internet.

5ghz is recommended for stability and indeed on 2.4ghz the games stutter but on 5 they do not. I am using the inbuilt apps on my tv but if 2.4 is active the tv's choose that, it is presumably stronger but less stable and the tv steers to the stronger, but cloud gaming is terrible unless connected to 5ghz.

There are still many users using Sonos in a wired setup with SonosNet active.

Wire the Arc, see how your Sonos system performs as well as your other devices you are looking to keep on 5GHz.

If you have issues, then you can look to resolve them or consider another solution to your situation.

If nothing else, simply add a 5 gHz access point and connect your games to it.
