Powerline Question

So I am looking at the TRENDnet 500 Mbps Powerline AV Ethernet Adapter Kit TPL-401E2K

My living room is on the 1st floor of a 2 story and the wireless from the upstairs office is not high enough for appropriate speeds for streaming. So instead of going through some crazy ethernet wiring options , this new Powerline seems like it might be an easy solution.

My questions are
1) Could the adapter plugged into the living room wall be then set into a switch of some sort in order to use multiple devices? (TV/PS3 specifically). What would I need to do that.
2) What would be the easiest way to test the speed of that plug (App?)
3) Anyone test these or seen a review against the Netgear models?

Thanks in advance!

1) Yes, you can normally patch a switch to these powerline adapters to support multiple wired devices.

2) NetCPS, Iperf, Qcheck, etc.

I don't know what kind of performance you'll get, but it won't be anywhere near 500mpbs, that's for sure. Even the more common 200mbps powerline adapters are lucky to get 10-12mbps in the real world, sometimes far less. Heck, sometimes they don't work AT ALL due to issues w/ the wiring in your particular situation. I would certainly *hope* these 500mbps powerline adapters were faster, but if I had to guess, I suspect you’d see real world figures in the 20-25mbps range under ideal conditions.
