ReadyNAS Duo giving very low access speeds on local PC

It's a broadband router rather than a switch and we both have the same broadband supplier and hence have the same switch (BT Homehub 5). I'd assumed it was running the latest version but it seems I neglected to update theirs when I last updated mine, we're now both running 4.1.14 (which made no difference). However, setting theirs to 100Mbps (full duplex) has now yielded a transfer rate of 3Mps (and rising, I assume because of Windows' averaging method) so I see that as a good result. Do you have any idea why running the NAS at 1Gbps and the PC at 100Mbps led to such a bad result? I'd have hoped the network could have coped with that... Thanks, Geoff

Most likely the router does not support ethernet flow control. Maybe try NasTester (http://www.808.dk/?code-csharp-nas-performance), it gives pretty good speed measurements (better than windows).

Anyway, there might be some tweaks to the Windows TCP stack you can make. You could also get an inexpensive switch that supports flow control (or better still get a gigabit nic card for the PC).
