ReadyNAS NV+ Seems really slow
I just bought a ReadyNAS NV+ 2x750 and am trying to transfer all of my data from a raid array to it so I can retire my old server. First I tried to use EMC to get all the files over to the NAS, but...
A. Lenovo X200s, Core 2 Duo L9400 1.86 GHz, 160GB 7200 rpm, 4 GB RAM, Intel LAN Mini b/g; Windows XP Pro 32 SP3
B. ReadyNAS NV+, 4.1.6
C. 802.11g router
D. Lenovo X201s, i7-640LM 2.13 GHz, 320GB 7200 rpm, 4 GB RAM, Intel 6200 wireless a/g/b/n; Windows 7 Pro 32
I just received laptop D as a replacement for laptop A. All is well, except for two problems that were NOT issues with the old computer (A):
1. VERY slow transfer of files from NAS B (mapped as network drive) to laptop D, especially over wireless, though it's not too speedy over a cable either. For example, opening up a 1 MB jpg took over 5 minutes on laptop D over wireless, but only 15 seconds over a cable. On laptop A, the process is no more than a couple of seconds either way. With laptop D, offline file sync is an apparently un-ending process (wireless or cable), whereas with A it is very rapid (either way).
2. Offline file setup with laptop D basically doesn't work. It is very slow, and gives thousands of errors (for jpg, pdf, xls, doc, etc) - all saying something like "this file is in use and could not be copied".

Solutions attempted
I have tried the following solutions:
*1 Mapping NAS B shares to a network drive using IP address rather than DNS.
No visible improvement.
*2 Command line: "netsh interface ipv4 show subinterfaces", to see MTU preparatory to resetting it to 1430 (or 1460 or 1492).
Command not found. True whether I run the command as administrator or regular. Some suggest this only works in Vista.
*3 Setting "oplocks" on for the relevant share in NAS Frontview |Network |Performance
No visible improvement.
*4 Running IOMeter as described in -5 above.
laptop A Read 1.72, Read 1.07 MB/s
laptop D Read .04, Write .84 MB/s
Vastly lower than the ReadyNAS results, so perhaps I'm doing something wrong. But D results still far lower than A.
Solutions not attempted
!1 I have not tried Radiator 4.1.7 beta, though some suggest this may help.
I'm not keen to risk essential data (even backed up) on a beta.
!2 Some solutions suggest installing and messing with Samba.
That is far beyond my technical expertise.
Help!
