Hi ICIT2LO,
I believe you are still confusing wifi extenders with power line adapters. Wifi extenders (just one) are usually placed half way between your router and the room where you want to use your computer. What they do is extend the signal of your router. It may be possible to use 2 wifi extenders but I never heard of it.
Think of a power line adapter as a network cable running from your router to the room with your computer. It's like you ran a physical network cable but they use the power lines in your house. You should do a YouTube search on Power Line adapters and their installation.
If you used a power line adapter, you could just use a network cable from the adapter in the computer room to your laptop. If you still want to use wifi, like chitownbob said, I think you need a access point. I've never used a access point so I'm not sure how they work but again I would do a YouTube search.
