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.

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

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

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?

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.
