Title: Slow transfer speeds
Post by: SpannerMagnet on April 28, 2012, 03:44:18 AM

Hey guys,

I got the ole' DNS-320 today and chucked a 1TB hdd inside. It's connected to my virgin media super-hub thingy-ma-bobber. I use a powerline/homeplug with most of the networked devices in my house.

I tried transferring a file using windows explorer and it's sending at 3 MB/second  :-\

This can't be right. Anyone know how to speed things up?

Thanks in advance! :D

Isn't the Virgin Super hub not so super?

Anyhow, are you using Cat 6 network cables? and what powerline adaptors are you using?

You are absolutely right my friend. Thr super hub is a modern, stylish big heap of s***e.

I've even tried setting it to 'modem only mode' and used my old netgear router instead but the speeds are still slow.

The powerlines are all 200mbps. I'm not sure what cables are being used though  :-\

Pop on ebay and pick up some CAT 6 cables, although too be honest even with CAT 5 you should see around 10 mb/sec.

The powerline/homeplugs are your problem, especially if there is a lot of noise on your mains wiring.  Under laboratory conditions the best one direction speed you could get is less than half the rated throughput.  Now transfer that to real world conditions and you can cut that by 50% to 70% and, in very noisy conditions, even more.  There are several other factors about power line adapters that have to be taken into consideration as well - efficiency and throughput is proportional to price is the main one, don't expect good speeds with cheap units.  Another is the quality and topography of the mains wiring.

Having shot down your network may I suggest that you try and construct your network with cable and where that is impossible, good wireless APs. 

A little ingenuity can usually hide the cables in most homes.  There is usually room for several cables just under edges of fitted carpets and there are several trunking systems that do duty as skirting boards.

You can also do a simple test using cables from the DNS-320 to your computer either via the Super hub or your netgear router and see what speeds you get with that setup.

Even if I plugged dns-320 and laptop directly into superhub. the max transfer speed achieved was around 10-12mb.  :(

Is the 10/12mb for uploading from your PC to the DNS-320? If so, what is your download (DNS-320 -> PC) throughput?

Those speeds sounds like you are using Cat 5 series cable.

Not necessarily. If those numbers are upload only, then 10-12 is tenable.
