Hi,

I would like to add powerline adapters. Right now I get:


  • 70 mbps on ethernet,
    60 mbps on wifi N,
    4 mbps on wifi AC (which I would have thought would be better than N!!)

I want to run the connection over powerlines to the other side of my house, through a sub circuit breaker box, so I know my connection wont be amazing, but it should be enough to stream. If I get get > 15mbps I'll be happy.

My question: If I buy expensive 1 gig powerline adapters, will they stand more chance of getting better signal than cheap 300mbps adapters?

I know even 300 is more than I require, but will 1 gig do a better job of getting a higher bandwidth because their tech is better?

Thanks, James

In general, the higher the spec, the more throughput. And nothing comes even close to the spec. I'm running some older 300Mbps powerline adapters (which I got dirt cheap, some as little as $5 a piece) and I get about 45Mbps. And that's even mixing different vendors (which surprised even me). But even so, that can vary depending on which outlets I plug them into, the distance between them, the amount of line noise, etc. But 45Mbps is more than enough for streaming.

So here's the bottom line. If you can get something older like 300Mbps spec'd and dirt cheap, you stand a good chance of it meeting your needs. But if you want to play it safe, it doesn't hurt to go higher, perhaps 500Mbps spec'd. The improvement as you move to higher...

So it's not like you have to go crazy w/ 1GB and higher powerline adapters unless your bandwidth demands increase substantially beyond what you've already stated. Or perhaps you just find a really good deal.
