Based on that and everything below, I'd suggest there is no packet loss..

So the network/LAN appears to be OK. The issue might then be the NAS not 
actually being able to supply the files - see Simons earlier reply, or 
some other issue, possibly with the virgin "super" hub thingy...

Unlikely to be the hub thingy, but you can eliminate that with a 2nd Gb 
Ethernet switch but given your situation that might be as tricky as 
connecting your Laptop directly to the NAS...
