Slow NAS (Synology) Transfer Rate

Router: Linksys RV042 (Firmware Version:
NAS: Synology DS207+ (Firmware DSM 2.1-0839)

Having owned a few Synology NAS, this particular transfer rate is extremely slow. When I try to open even a 100kb word document, it pauses for 30 seconds before opening, when I open a 2mb photoshop file, it takes over minutes. There're only around 5-7 users connected at any point with very low usage.

Can anyone advise how can I trace the performance issue of the NAS?  Is it possible that having VPN turned on (IP becomes 10.116.171.X) on the Router affects the network performance?

I found out the reason is that Linksys RV042's Ports needs to be on Auto Negotiation mode and not 100M Full Duplex.

are all NAS devices sitting on the same internal subnet behind the router?

when you talk about accessing the NAS, is it internal access or that through VPN?

All sitting on the same internal subnet.
Accessed on local LAN.
The PCs and NAS are connected to the same Router  (Linksys RV042).
When I transfer a 100mb file,
PC to PC transfer at around 4mb/sec.
PC to NAS (or NAS to PC) transfer at around 700kb/sec.

PC to the specific NAS? or any NAS?
I would start to check if the NAS filesystem is healthy.
Improper shutdown might damage the filesystem.
