Hi I am considering getting am adapter. I live in an apartment where runnin wires is not an option. I recently got verison FIOS  one. So i can finally have a cable box in the master bedroom. But for some reason the connection is awful.So I think that this power line adapter is the solution to my problem. I have the gigabit connection. So for those that have then do you think it work? Is it fast enough and reliable enough to drive a tv cable box?
