A WHILE BACK, I linked to a review of Monster’s power line networking technology. I’ve followed that stuff for years, but it seems to have gotten better. On the strength of that good review, I ordered the starter kit and installed it over the weekend. “Installation” just consisted of plugging one unit into the wall near the router and connecting it with an Ethernet cable, then plugging a corresponding unit into a power outlet in her room and connecting it to her computer with another Ethernet cable. It worked perfectly immediately, solving an annoying problem with spotty wireless coverage in the Insta-Daughter’s room. If you’re worried about wireless security, you could give yourself a wired network with these things quite easily, though it’s a bit pricier than wireless.
