A:Answer Ha, ha...I'm answering my own question (in a way). Someone posted that the receiver and main bar CANNOT be programmed to a certain 2.4 Ghz channel, and I am confirming that is the case. (Bummer) I've found, since my unit came in, that there is random interference when a bunch of people are on the network. I know that, perhaps, it's not necessarily LG's issue, but stutter from my ISP's router. So far, though, the signaling has been super clean most of the time. Highly recommend turning-off auto on, and keeping the system undiscoverable after pairing all of your devices. Would not be fun to have a neighbor accidentally connect at 3 in the morning, and scaring the living 'ish out of you and your family! After having read reviews for some of the other LG options where this very thing was an issue, I decided on this particular model 'cause you are given control.
