A couple of things to try.
First, a simple reboot of your router might be in order. It’s possible it’s in a state where it is blocking the assignment of the IP address to the Arc and PLAY:1.
Second, if that doesn’t work, try temporarily wiring an ethernet cable between the router and the Arc, and see if it completes setup that way. If so, try the same with the PLAY:1. Or maybe reverse the order, surely it is easier to put the PLAY:1 closer to the router to get it wired directly than it is to move the Arc, or string a longer ethernet cable. If it doesn’t work on the PLAY:1, it likely won’t work on the Arc.
If neither of those work, it might be nice to post what router you have, so that we can see if they are one of the troubled sets (BT and Asus come to mind), and if someone has particular knowledge to share, they can do so.
And before you return anything, you really may want to try calling Sonos Support directly to discuss it.
When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your Sonos system and network.
OK so after a LOT of messing around last night I got it working and have figured out the problem! I ended up factory resetting my Asus Router (mesh wifi) and splitting the WIFI bands. My original setup was sharing the bands and after splitting to seperate 2.4Ghz and 5Ghz channels, it now all works.
And the Arc sounds absolutely amazing, so I have gone from tearing my hair out to be over the moon!
Some things I have learnt through troubleshooting and googling:
- With Asus routers ensure Airtime Fairness is turned OFF
- Split your WIFI bands, so seperate 2.4Ghz and 5Ghz Channels, it seems that Sonos devices have problems connecting to a shared setup.
Thanks for your reply!
