Best Buy had a good price on some powerline Ethernet adapters so I finally got a few. I'm hoping to use them with two of our Tivos that are currently using wireless USB adapters. They are S2 Tivos so they only support WEP encryption, so once I move them to a wired network I can up the security of my wireless setup. Anyone have any good or bad experience with powerline Ethernet? These are the adapters I bought: Actiontec - MegaPlug Powerline Ethernet Adapter (2-Pack) - HLE08500-01 Online reviews seem pretty positive.
