I have just received my Sub to complete my surround system. Every time I tried to pair it with Arc I was getting a failed connection message. After quite a few attempts at pairing the sub, and a factory reset later, I discovered that the sub would only pair with the Arc when I switched the Arc from wired to wireless connection. Now my system is working great and all speakers are connected. But when I switch Arc back to it’s wired Ethernet connection, I loose the sub speaker again. As anyone else encountered a similar issue? I also have a pair of surround one SLs which I had no problem pairing with Arc.
