Query: Doesn't Work

This does in fact allow you to run ethernet over your home wiring. What they fail to tell you is:It doesn't work reliably with DHCP provided by their own linksys hub.It doesn't work through all the plugs in your house, even if your wiring is only a few years old.Once you get it working, it stops working after about six months when one of the little boxes becomes unable to see the other one, though the inverse isn't true.All in all, a shoddy product with shoddy software from a company I used to respect.(Later addendum: after sending the boxes back to linksys, I have two working ones again. Still, they shouldn't have broken in the first place, and still have all the other problems.)
