Network question when using older and newer components

Hi all, 

I currently have a sonos arc (non ultra) paired with a sub gen 3 and two era 300 as surround. I also have a beam gen 2 and two ones in other rooms but my question is this…

I want to turn off my 2.4g wifi signal and only use 5g and above on my router. My arc and sub gen 3 won't work on this band but the era 300 will.

I am wondering if the setup will work if I hardwire the arc to a router (which the sub can join along with other older speakers via sonosnet) and also have the era 300 (and beam) connect via 5g?

Will they still all work together and will the era 300s still work as rears to the arc, as the arc will he hardwired but the eras will be wifi 5g (I believe the eras will not use sonosnet as it is phased out on newer speakers)?

I hope it am making sense. Any help is appreciated. 

P.s the reason I want 2.4g off is some other devices prioritise it but I need them to be on 5g for stable cloud gaming and they don't have manual selection.

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.

https://support.sonos.com/en/article/supported-wifi-modes-and-security-standards-for-sonos-products

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.
