Hi guys,

I have a new NAS and I'm transferring data from the old NAS to the new one on my LAN. Both devices are connected to the network using homeplugs.

I'm using Fastcopy to transfer data and a small laptop I have in my loft transfers at around 1.55mb/s...my main PC that is connected straight into my router is transferring at around 0.25mb/s...the other PC I have in my office transfers at a similar speed.

Are there any diagnostic tools I can run to see why the big difference? The Devolo homeplug shows it's connected at a 70mbit/s where as the other PC I tried is plugged into a router that is showing 150mbit/s.

Any ideas?
 
1.55MB/s (12.4Mbps) is very poor, 0.25MB/s (2Mbps) is virtually stopped. You're talking ADSL speeds rather than LAN speeds.

The kit you're talking about sounds to the fairly portable. Can't you get everything close enough together (at least temporarily) so you can use cables? If you don't it'll take forever to move any significant amount of data.

Taking the homeplugs out of the equation will help to identify the root cause.
 
Yeah I understand they're horrific speeds, it was more a long term fix rather than this transfer job I'm currently doing.

I do live in a very old house so I can imagine the electricity has most of the bearing on the issue, the homeplugs are 100mb jobbies.
 
If they're 200 AV adapters, and they're performing that badly, you'd probably be better off with wireless.

If you can temporarily hardwire the equipment you'll be able to prove that the homeplugs are the problem, or not.

How fast are the NASs supposed to be? There have been some very underpowered devices sold over the years.
 
I'll wire the two NAS into the router and see if that's better.

Cheers

Indeed the NAS's plugged into the router are transferring are a lot quicker. I only got the homeplugs origionally as streaming videos over wireless used to be a laggy mess, having the homeplugs stopped this.
 
Those are exceptionally slow speeds for homeplugs, I get 4.5MBps (36Mbps) from the internet, limited by my FTTC speeds, never mind over LAN. Typical Homeplug 200 LAN throughput is anywhere from 5-10MBps

Could you just get a big Ethernet cable for the one off transfer? Or physically move one of the boxes to be on the same switch as the other?

Oh, and you're not using an external IP/domain when mapping the NAS for the transfers are you? I made that mistake once, using the domain name (mapped via Dynamic DNS to my broadband IP) instead of the hostname, meaning that the traffic was going through my network to the router, out to the internet, back into my connection and through my LAN again to another machine on the same switch....
