Considering leaving Sonos entirely?!

Does Sonos work okay with it then? 

@ratty I haven't had time to take the test yet, it will be done this week because I have a little more free time. But I like to find out what to do beforehand.

Well, to be honest I don’t really understand why there’s a dedicated AP for Sonos. Sonos ought to work on ‘HOUSE1’, i.e. the Orbi mesh. Moving on...

On the assumption that ‘HOUSE2’ is the only SSID stored in the Sonos system then returning to your question here I’d suggest you connect new Sonos devices to ‘HOUSE2’ and anything else to the Orbi’s ‘HOUSE1’. Both SSIDs will be on the same IP subnet.

Ok then if both ssid will be on the same ip subnet then there are not need to rename it to the same ssid and same password like explained earlier?

To be frank I don’t understand the rationale for installing a separate AP. What model is it? What channels is it using? How is it better than the Orbi? 

Its been 2 years now you non stop told me that i have network interference issue. Then isolate them to an entirely new network is not a good idea?

It was Sonos Support -- who actually have access to the diagnostic data -- who said you have a wireless interference issue. They in fact suggested wiring as many devices as possible.

I’ve certainly not recommended setting up a separate AP. If it’s in the same location as the Orbi primary node it’s likely to do more harm than good. 

Just to try to put the record straight here… That’s not what I was saying @Thewizard2000 - it seems like you’re now using double NAT in your case for your Sonos setup. I merely suggested that you follow the Staff advice in the link I gave you and to perhaps switch and run the Orbi system in ‘bridged AP’ mode, rather than ‘router’ mode, meaning that you do not use an Orbi ‘primary’ Hub as your main router, but use a 3rd party router instead, with its WiFi disabled and switch the Orbi to become the local subnets wireless access points - I suggested it would be ideal aswell to wire the Orbi AP’s back to the router, or an adjacent switch, if practicable. I did not mention setting up a second router and begin using double NAT, if that is indeed what you’re currently doing 🤔? - that would be entirely different to what I was suggesting earlier in the thread, if you perhaps look back at my posts.
