Experiment in Terror

My Wi-Fi Fu is weak, decrepit even - but it's free (for now). I'm going to try somethign with Powerline Ethernet. I doubt a new DSL provider will improve things wirelessly as we're surrounded by a thicket of ten other secured, home wireless networks.
That's up from about only four just a few years ago. Now everybody's got to have one, and the air is cloying with humming bytes and buzzing bits.
