Any Amateur Radio Operators (AKA "Hams") Here on The HughesNet Community Forums?

Hey, not a ham operator but I do have a problem with someone skilled in radio... I use my hughes.net like most people pretty much have the laptop and blueray player going constantly streaming a movies etc. New guy moves in and is paranoid about someone spying on him. From the questions posed by this man he thinks when he picks up our wifi (hughes.net) that it's cameras looking at him. Long story short we don't have any cameras connected to our wifi. All we can figure he thinks someones trying to trap him poaching. But I stay busy in my own little world and don't worry about anything else until my wifi starts getting interrupted continuously. It's works great for a few minutes then my dog gets in the window and barks in the direction of this new neighbors house and my wifi gets jammed etc. He had mentioned that he uses an illegally overpowered amplifier and linear and bilinear ? I have no idea what that stuff means and I guess I will need to learn but my question to you or anyone who might want to help is : Is there a particular filter I can have put on my dish to prevent his interruptions? I mean he asked us once if we had wireless cameras linked back to our house and I told him truthfully NO. So I need to adjust my own enterainment system to keep him out. I am not going to try and prove myself to a rogue radio madman. This is my first experience with this sort of thing. Any help would we be greatly appreciated. I called hughes.net tech support and they said they have no filters and no nothing about it.
