Powerline/homeplug question

Hmmm, done a bit of reading on the 500Mbps adapters and a few people seem to think that if you divide the Mbps speed by 8 then you arrive at roughly the MB/s throughput (ie. 62.5MB for the 500Mbps ones)

Does this sound reasonable to the knowledgeable bods around these parts??

As long as the fibre speed isn't bottlenecked then I think I should be OK so the 1200Mbps plugs seem to be overkill!?!? (having said that, is there any benefit in going for homplugs with gigabit ethernet??)

Dividing by 8 does convert Megabits per second to Megabytes per second, but this isn't applicable in this case.

AV500 (500 Mbit/sec) adapters are likely to max out at around 70Mbit/sec (single stream), maybe a bit higher, maybe a lot less. Have a look at the information over at Small Net Builder http://www.smallnetbuilder.com/tools/charts/powerline/view for a better idea.

Thanks for the link - doesn't have all the adapters I'm looking for on it but at least it gives me an idea!

I think I might just bite the bullet and go for the 1200Mbps plugs - at least then I'm prepared for any speed increases in the future as well as getting better file transfer speeds in the meantime!

AV600 are worth a look; cheaper than AV1200 but still based on more modern chipsets than most AV500 adapters.

I did have a look at the 600Mbps adapters but I've seen the Netgear PL1200 Powerline Adapter Kit - Twin Pack for less than £50, which seems to be not much more than the 600's cost for theoretically double the speed??
 
Here's a question - I went for the 1200Mbps TP Link powerline kit in the end.

On my wireless laptop I get around 70Mbps (same room as the router)

On my PC 2 floors up, using my old 200Mbps Devolo homeplugs, I got around 28Mbps

With the new TP Link powerline adapters I'm getting around 64Mbps - so obviously a decent improvement but still not as high as on the laptop - could the homeplugs still be the "bottleneck"??

I've run the little TP Link utility and it's telling me the link is operating at anywhere between 140-171Mbps - does this sound about right for the 1200 speed adapters??
 
Although the new adapters are working better than the old ones they will be causing the reduction in speed you're seeing.

You could try unplugging other equipment to see if you can remove some interference from the connection. Mobile phone chargers are a prime example.

Just using different sockets in the same rooms can make a difference.
 
Powerline adapters are only as good as the electrical wiring set-up in your house and the separation along the electrical cabling between two adapters. I would suspect this is your limitation now.

That is correct (the maths to work out the Max transfer speed).

But because power line is a terrible solution, you'll never get anywhere near that. More like 15MB/s Max. Which is horribly slow if you're transferring data.
