I really don't think adding the Duet did it but I've seen stranger stuff. Wired is the best way to go....I see no advantage to wireless unless you have no choice because of construction, because all they do is drop out at the most unconvenient times..think great Christmas party, you got a nice buzz and it drops out and your thrown into wireless hell while everyone stands around telling you what uncle hal did when the old radio they had gave out---LOL....and the happening looking woman you've been chatting up all night gets hit on by Tad while your away and he's winning!!!
I run mine wired and still get dropouts sometimes when power goes off and on real quick-not saying that will happen to you.
Good luck and if it happens again..throw it at the wall!!! KIDDING!!!
