Hi, hopefully you can help me out here.
I was able to connect my Arc, 2 Era 300s and the sub 3 in my network having 2.4ghz with WPA/WPA2 authentication as it is the bare minimum requirement.
First step was connect my sub to a room, which is with my Arc. after connecting, it says that the Product is not connected. which is weird.
I tried to setup the surround with my 2 Era speakers and Arc, still ended up with the same error message on both Era speakers.
I have also added their IP & MAC adresses as dedicated devices under the DHCP list and still got the same error messages and result of not having all of them turned on.. except for the Arc itself.
Basically I did the LAN cable thing and yes it worked but I cannot affort to have my cable running across the floor as it was only a test.
I rang up the support which they said its a DHCP issue, which I never had before after their upgrade of my sonos products recently.
