Networking :: Ethernet Cable Alternatives ASUS PCE-N13

So I finally got rid of the network cable across my hallway, yes it was faster, however It was ugly and I just didn't like it being there or having to cover it etc.

My attic makes a simple drop very difficult. I would need to cut into my plaster walls and hire a drywaller who knows how to work with plater to fix them, then re-paint my walls etc.

I always thought wireless N would be too slow to stream larger H264 files mkvs etc. So I bought a new ASUS Wirelss AC router, and AC network card.

I also bought some toplink 500mbps power outlet transmitters to test in the bedroom. This PC also has a ASUS PCE-N13 300MPS wirless card (150MPS upload), that was missing antennas. I borrowed some wireless g antennas fro some old routers to to test it out. For the Tp-Link Power Line adapters I tried 3 plugs that are all on the same braker, and in fact are wired off the same run.

Both living room and bedroom are pretty close to the office, with 2 walls (but also 2 door ways that line up through a JackNJill bathroom (so no walls?) directly into the bedroom. The living room has to go through one wall and around the hallway corner.

So the ASUS AC network card picks up the router at 833Mbps in my living room.
The ASUS PCE-N13 picks up at 150/133 Mbps in the bedroom.
The Toplink 500Mbps powerline adapter is shows as 100Mbps.

When plugging in the powerline adapters the Gig router it as a 100Mbps line too (Yellow light). Shouldn't this register as a Gbps line? How can they claim 500Mbps is they are only using a 100Mbps controller?!?!

So it seems like wireless N is working much better for me than the powerline adapters? I really like the hard line style of the adapters, but it concerns me that they are only detected as 100Mbps devices. How can they be detected as 100Mbps but claim up to 500Mbps? Should I send these back and try different powerline adapters? Or maybe I should just get another wireless Asus wireless AC card.
