Query: Great, when it works

The instructions for this product explain that if you haven't established a network connection between the wall outlet units after plugging both of them in, "try pulling [one of them] out of the outlet and plugging it right back in." This is good advice, because you'll be crawling under your desk to do this 2-5 times every time your computer wakes up from sleep or reboots to reestablish your "always on" broadband connection. I'm sure some people might be lucky enough to have success with this device, but that's of little consolation to me. $100 or thereabouts is too much to spend on a product that "sort of" works. I'm sending it back.
