Let me tell you guys a little Internet trick if you are having a problem in a certain area of your house. Almost everyone has an old wireless router if you live in the technology of the times, and Internet is important. Just plug an ethernet cable into the router coming in, and plug it into another router somewhere else in your house, the chance are that you already have that router saved in some of your systems. Don't have to buy a booster that way. But your ethernet through Amazon and save about $50, as compared to Best Buy.
Use ethernet cable everywhere you can, and RF interference won't bother you.
