500Mbps Nano Powerline Adapter - these work well

[TotesTurtle]

On speed test I get 54Mb on my PC on a 1 metre CAT 5

and in my living room on the Homeplug I get 46Mb

so that's pretty blumin fast!!

Ewwwww

For it to be limiting your download speed means you're not getting anywhere near the 500mbps it's rated at, in fact Wireless N would be better, (although a bit more latency).
Personally I just stick with drilling holes for CAT 6 XD

In my experience, they are better than my wireless N router over the same distance.

Same here, and that is comparing a 3 antenna access point not some generic router that is trying to be everything.

As for drilling holes for Cat 6, I once drilled holes for Cat 5 and it was a pain in the butt. I supposed I could pull the carpet and floorboards up after moving the furniture out of the way and lay cable under the floor, or I can plug in a homeplug adapter and not lose several weekends to a job that in a few years I will need to do again to pull the cat 5e (6 isn't worth the aggro) and replace with fibre for 10GbE.

I think it very much depends on the house, but homeplug for me is the best option.

Depends on the signal quality I guess.
I have used them for other people, for example my cousin's wireless signal doesn't reach to his room so they are a godsend for those type of situations.
I had some 200Mbps ones and it turned out I only got around 45mbps over the LAN, which wasn't fast enough for my liking so they went back in the box.

Wireless N is no where near as fast.. checked that before plugging them in.

My Draytek is a great router but these homeplugs are way faster

When powerline adapters work they are great, but unfortunately I don't think my internal wiring is up to scratch as there were always too many random network drops (and it wasn't just confined to one brand/model - though the one in the OP wasn't one of those used), so I gave up and went the messy route of trailing an Ethernet cable directly to the router instead.
