just as an experiment I ran a Windows 10 Virtual machine from within my main Win7 machine. Using Helios Lan Test I got a consistent 24MB/s both ways to the NAS. The virtual machine was working hard on another task at the time so I didn't expect to get high transfer rates. However the significant points are:
Read/Write are the same.
Much higher than the 6-9 MB/s write/30+ Read I'm getting from the Windows 7 machine that is running it.
It rules out NIC problems or LAN connectivity problems on my main Win7 machine.
I tried using SMB Plus to change the SMB version on the NAS (yes, I did reset the client each time) but it made no change.
I tried running lan test from a Mac (connecting first via SMB and then via AFP). I got 20MB/s Write, 29 Read.
It would point to being a specific issue between Windows 7 and 6.4.0+
As another experiment, I booted up a virtual machine copy of XP. Got 24Mb/s both ways from a virtual machine running on Win7. That same Win7 machine reports 5.5 write, 29 read.
So at the moment the ONLY OS that has a problem with writing to the NAS after 6.4 is Windows 7.
Mac OS, XP, Win8, Win10 regardless of hardware and even running as virtual machines all have no problems.

Interesting.
Yes. I think it points to something specific on the Win7 system (since my Win7 system doesn't see that slowdown with my RN102). Do you have internet security software or AntiVirus running on the PC?
Though 25 Mb/s is still slow (post factory reset I am seeing ~75 MB/s).
I used a Windows 10 machine to host a shared directory on the same local network. Not a high-end machine, not optimized in anyway as a server, basic windows share.
Results are:
Win7 host machine: Write 33MB/s, Read 32MB/s
XP VM on host machine: Write 30MB/s, Read 29MB/s
Win10 VM on host machine: Write 28MB/s, Read 29MB/s
From apple machine > shared directory: 22MB/s, 22MB/s read

Interesting. So performance is approximately the same for all protocols (and actually lower than I'd expect for all cases). This is with gigabit? What model is the Win-10 machine?
It does say that the issue with on the win7 system is specific to the NAS.

The machine I used to host the shared folder is 8 years old. not the fasted in shape or form. I'm not interested in the overall speed but how symterical the read/writes are. i.e., in this case they are pretty much the same read/write.
Whereas Win7 to NAS is not. 6-9 write, 30-40 read.
so again, not worried about the overall speed. The point being that it's not showing the same issue as the win7>NAS.
I agree that the win7 performance is the main issue. At this point I'm starting to lose track of what we've already tried...
-It might be useful to install the SMB-Plus app, and configure the NAS to use SMBv1, and see if that changes anything. XP uses SMBv1, Win7 uses SMBv2, and Win10 uses SMBv3.
-Does the win7 PC only have ethernet? If it has WiFi also, perhaps try turning off the radio and retesting.
-Are there any VPNs installed on the win7 system (readycloud, openvpn, work vpn...)

ha! I know what you mean! I'm loosing the track/plot too!
I have smbplus installed. I've tried smv v2,2.1 and 3.0. will try v1 now for a laugh
win pc only has ethernet.
no vpn's installed.
same asymterical performance from a different win7 machine.
I even ran a win7 vm from an Mac! saw the same performance problem! (performance on the mac itself was ok of course).
Average write about 5-6MB/s. Average read is 30-35.
Driving me mad. Can't see any solution. Trying a new NAS (synology) this week to rule out the RN104.
Again, Windows 8/10 + Mac machines work perfectly (even virtual machines on running Win10 on the Win7 machine). This has only occured since 6.2.5 > 6.4.2
At my wits end now. I write large files (photographs and video) and 5MB/s is impractical.
I've tried googling and implemented fixed for all known issues relating to slow transfers on win7. Nothing works. Things include:
Connecting the second network adaptor on the 104 and it's the same performance issue through that connection.
Completely disabling ipv6 on router, NIC and RN104 NIC's.
Resetting the TCP stack (in case of TCP timing issues)
Disabling firewalls and antivirus
Changing the switch
Scanning for malware (not sure how that would affect write speeds but I did the scan anyway)
Changing the SMB version on the RN104 to force it to v2.1 (win 7 level) but I tried all other levels too (1.0, 2.0, 3.0) and that didn't change anything much.
Now, I do have a spare RN104 (unboxed), so if I can find three spare disks to create a RAID5 array then I might try that (hopefully not on 6.4.2, try to make sure it's on 6.2.5 or lower).
Other than that I'll see how the synology fairs up and take it from there.
