need help installing and using powerline adaptor

i just bought the powerline av 200 nano adapter kit xacb2101, and i cant figure out what i havent done to get this to work, i have a wireless network but im getting a terrible signal so im turning to this after a buddy told me it was the solution to his terrible internet.
i have the adapters plugged in, on in the wall and plugged into the router and the other plugged into my wall and into the computer. it just came with the adapters and ethernet cables no cd for installation, which i had to download off the internet.
now im stuck on what to do to get this to work, have my passwords written down but i thought it was a plug in and go but im guessing im wrong. it shows im connected, shows communication, shows im less than 50 mbps since the led is red. so its not letting me connect as if im using a wired connection. Any help would be greatly appreciated.
