appairage impossible du sub4

Translation:

I bought an Arc Ultra set and the Sub 4, but I can't get the two to pair! What should I do? Has anyone else had this problem, and if so, how was it resolved?Thanks in advance for your replies.

Can you tell us about your network/router?

Do you have good signal where the Arc Ultra and Sub are situated?

How far is the Sub from the Ultra?

Have you performed the steps found here:

Is wifi turned on on the Arc Ultra?

In general, the Arc Ultra connects to your WiFi, the Sub 4 will ‘bond’ to the Arc Ultra using a ‘hidden’ 5Ghz channel, and receiving a proxied IP address from your router. As suggested above, this does mean you should normally be leaving the WiFi / radio turned on on both the Arc Ultra and the Sub 4, even if you have the Arc Ultra (or both) wired with an Ethernet cable. 

However, if you’re still experiencing challenges, I’d recommend that you call Sonos Support to discuss it.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

Translation to French:

En général, l'Arc Ultra se connecte à votre WiFi, le Sub 4 se "lie" à l'Arc Ultra en utilisant un canal 5Ghz "caché" et recevra une adresse IP proxy de votre routeur. Comme suggéré ci-dessus, cela signifie que vous devriez normalement laisser le WiFi / la radio allumé à la fois sur l'Arc Ultra et le Sub 4, même si vous avez l'Arc Ultra (ou les deux) câblé avec un câble Ethernet.

Cependant, si vous rencontrez toujours des difficultés, je vous recommande d'appeler le support Sonos pour en discuter.

Lorsque vous parlez directement au personnel d'assistance, il dispose d'outils qui leur permettront de vous donner des conseils spécifiques à votre réseau et à votre système Sonos.
