Networking options

You need to have both devices plugged into the same power circuit.

I'm not an expert on this, but have worked with other devices signaling over the power lines. Chances are you can use more than one circuit...you just need to stay on the same phase unless you have a phase coupler to pass the signal between phases. I'd suspect your church building has three phase power (since you're in the U.S.A.), so there are three phases. I don't know how far the signal will propagate.

You might find that things like motors from HVAC systems make things work better or worse when they're on. For example, I've heard of cases that electric motors when running can bridge the phases and let the signal get to the other phases and when they shut off devices stop working. But I've also heard that the motors can be noisy and kill the signal even when it's on the same phase.

I just mention this in case it helps you get more out of your solution that seems to be working. If you're not familiar with three phase power and how it works, you might have an electrician in your ward/stake who can help you identify circuits on the same phase. It's worth a try and might give you more options on how you use your powerline ethernet adapters.

The reliability is somewhere around wireless. All it takes is one noisy device being plugged in and you're toast.

In older buildings it may not be possible at all. At our stake center I tried ethernet over power and learned that due to the way that the building was wired it was impossible to get the network connections to work - the electric connections in one part of the building were physically separated from those in the other parts.

They still rely on wireless, when doing events, one of the primary steps to success is to eliminate wireless to limit issues related to bandwidth being taken by numbers of members in attendance. I don't disagree that it can be useful in circumstances, but I'd never want to upload or download stake conference or any stake meeting for that matter on the device.

Powerline Ethernet adapters don't use wireless at all. I suppose an easy solution (easy if it works), would be to use powerline Ethernet adapters to physically connect the presentation computer to the Internet, then physically disconnect all the wireless transmitters from the firewall to eliminate the competition.

Currently we cannot shut down the 881W wireless locally. The signal range can be reduced by removing the antennae. But the signal cannot be eliminated.

The simplest thing you can do to stop the signal after you remove the antenna's is to get a small piece of metal screen (think screen door on your house) a 6" x 18" will do. shape it like a long U and place it over the antenna ports. No signal will get through.
