I am using a Synology DiskStation DS2413+ in a mixed OS environment. It is connected via 2 ethernet cables to our n router (Asus, will update with details). When I mount the NAS via smb to an OS X 10.10.x box, transfer speeds are as advertised (something on the order of 50 MB/s over wifi lan). When I have a Windows 7 box connected through the standard Windows networking via ethernet to the router, I also get fast transfers. CloudStation transfers are also fast on both of these machines.
On another Windows 7 machine, which has no problem with fast internet via its wireless n card through our lan, we are experiencing excruciatingly slow transfer speeds to the nas (2 MB/s peak). This machine is slow over both CloudStation and Windows networking but again is fast for everything else. What could be causing slow wireless transfers to Windows with the nas?
Any help is greatly appreciated; happy to provide complete technical details if necessary.
