He has a very interesting -- and especially easy -- solution for a problem that I suspect a great many people deal with: home WiFi that's unable to send a strong enough signal through your home.
Todd was having the same problem himself (yes, even high-techies come up against glitches in the real world), and -- like most people in the aforementioned real world -- went to friends for advice. What he came across surprised even him. Setting up "mesh networking."
Not to worry!! In fact, I was reticent to give its name, because I'm sure that will terrify a lot of people. But if you read his article, you'll see how easy he says it actually is. And it sounds extremely easy -- just not "Easy for Someone Who Knows What He's Doing." It took him all of 10 minutes (actually less), and even if that's because he's someone who knows what he's doing, it still sounds extremely easy for normal human folk.
You can read his article here for the solution.
