Boost will not connect to new Asus RT AX-88U router

I recently replaced my home router with a Asus RT AX88U router. After setting up my router using the same wifi name and password, I started my Sonos app. All my speakers were recognized and connected. The only component that would not reconnect was the Sonos boost. I tried a factory reset and the boost went through its startup, led flashing white / orange, then changed to a slow flashing green. The boost will on connect and I am at a loss. Thanks in advance for any help.

With the One wired all the rest, except for the Move, should have moved over to SonosNet, and hence the router’s wired segment. Strange that they disappeared.

Is the Asus router the sole source of a WiFi signal, or do you also have mesh units or extenders?

There’s some things to perhaps try mentioned in this earlier thread…

So I just spent some time with Sonos Support and it appears my problem lies in the fact that the Asus router has a 2.4 and 5G network. The boost when connected has been running on the 5G network. The move is connected to the 2.4 network. In Canada, the move is only capable of running on the 2.4 network. I will be contacting Asus to see if I can force the boost to run on the 2.4 network which will then allow me to access all speakers. Otherwise, I have to switch networks on my controller to see the different speakers.

Sorry, but not a lot of this makes sense. The Boost doesn’t run on any kind of WiFi. It’s either wired to the network or connects wirelessly over SonosNet. You can’t ‘force the Boost to run on the 2.4 [WiFi] network’, because it doesn’t use WiFi.

If a controller on one of the WiFi bands can’t see the Boost the fault is in the router. Some don’t correctly forward discovery multicasts/broadcasts between network segments. Having dual bands is not a ‘problem’ at all per se. 

 

I also don’t understand the comment about the Move not working on 5GHz in Canada.

I don’t understand it either but will be contacting Asus to see if I can get further.

In Canada, the Sonos Move only operates on the 2.4 frequency. Restricted for whatever reason. 

To stream my music, I currently am using an Ipad or android cell phone. When I open the sonos app, and my Ipad is connected to the 2.4 network, all I can see for components is the Sonos Move. If I switch my Ipad to the 5G network, I can see the Sonos Boost, play bar, sub and sonos 1. For whatever reason, I cannot get all the components onto the same network. Sonos Support recommended that I contact Asus to see if additional parameters need to changed in my router so that all devices can be available on the 2.4 network. 

Hope that clairifies things slightly

You are taking about this Sonos device, aren’t you?

Yes sir.

And BTW, Asus support just told me that the problem is with Sonos. 

And Sonos says the problem is with Asus. 

I guess, I will keep on battling and see where it gets me.

So in reality all the Sonos devices are connected to my router. The problem I am having is that to utilize the Sonos Move I have to have my Ipad connected to my 2.4 network. To utilize all my other Sonos products, I have to have my Ipad connected to the 5G network. I cannot connect my Ipad to all devices at once.

Just to be clear: your Boost is cabled to your router and can only be seen by devices that are on the 2,4Ghz network?

There’s been more reports of routers not being able to fully connect between 5Ghz, 2,4Ghz and cabled parts of the same network. Recent incidents are BT in the UK and KPN in the Netherlands. Your problem sounds like is lies with Asus.
