Good guess! Numpty alert! :)The basic system is my desktop PC with Gigabit onboard - drivers all OK. That goes into my Virginmedia 'Super' hub which claims - according to the activity lights - to be connected at Gbit speed. That then links to my Synology NAS which has Gigabit onboard. All cabling is CAT5. Ergo all things being correct it should be going faster than an absolute maximum on occasion of 40mb/sec. It's WAY simpler than any network you're dealing with I'm sure :)
What makes me suspect the cabling is that I've never got Gigabit speed over it, even with a previous router that had Gigabit and my previous NAS which did as well. What I *have* noticed is that since swapping out the old NAS the speeds have leapt, so that was at least part of the problem. However the only thing I haven't changed yet is the cabling.
BTW I do know about Gigabit v Gigabyte.. had the unhappy job for 6.5 years explaining to ISP customers that 'No you won't get 56 kilobytes a second on your modem.. you'll be lucky to get 4..' then explaining the 8 bits + stop bit + check bit part meaning 'Divide by 10, chop off a bit for resistance/latency and you'll get close'. I'm hoping for a bit more than 40% of the absolute maximum running downhill in a hurricane of 100Mb/sec though :)

Oh yeah, Julian did! Am going to continue assuming he meant gbit :)On 2 April 2013 12:53, tom <tompotts@xxxxxxxxxxxxxxxxxxxxxx <mailto:tompotts@xxxxxxxxxxxxxxxxxxxxxx>> wrote:But you wrote Mbit!

And also at the interfaces at either end. Are they set right? If one end is a pc, is it using the right drivers, are they configured correctly? Is the other end gbit capable? Is there a 10/100 switch or hub forgotten in the middle that isn't? Also, check link speeds rather than throughput. "not giving Mbit speeds" could mean you're assuming 1 gigabyte of data per second rather than the typical 1/10th of that, with a following wind and no other traffic on the network, AND that the kit either end is capable. (Hint, many user grade switches can do a 1mbit link, but can't sustain megabit data flow - they just don't have the processing power) Cat6 is a sod to work with, but will help with interference issues to a degree if done properly. Don't just assume it's the same as cat5e to work with, though. I'm almost certain that in a home environment, you're better off re-using the existing cat5, or running new cat5e away from mains/noisy areas. IME, most cat6 use cases are more cost effectively done with cat5e, which costs buttons.

I have cancelled my eBay orders for the Xeon stuff, it was crazy & cool but not practical. Now i'm torn between owning a Synology, Building a cheep Sempron type PC or a budget AMD F1 based PC for backup and file storage filled with Linux goodness. =) Daniel I bought it to replace a cheap and cheerful NAS from Maplin. However, now I need to upgrade the flippin' cabling as well.. CAT5 is not giving Mbit speeds.. needs upgrading to CAT6. Julian ??? my battered old cat5 manages 100Mb over 25m 'easily' Tom te tom te tom-- The Mailing List for the Devon & Cornwall LUGhttp://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq-- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
